Obtain the good ginseng seeds of breach to 10 the end of month.

A kind of level land ginseng planting's method comprises the selection of (1) soil, (2) land improvement, and (3) are mounted the throne and are taken sunshade, and (4) ginseng seeds is selected and germination treatment, and grow seedlings (5), and (6) select seedling, and (7) plant transplantation of seedlings; (8) genseng field management; Wherein:

(1) soil is selected:

A. in the area between north latitude 34 degree-48 degree; Select the northwards broad or northeastward in the place ahead, inclination or level land need only the good sandy loam of draining, all can more than the dark 30CM of soil layer;

Grass family such as B. genseng has unique abnormal reaction disease to soil, and the crop rotation soil should need rotation cycle more than 10 years, and to plant a banker be corn to stubble before will selecting when selecting dry land ground, the wheat class or legume crop are for well;

(2) the land improvement time is to carry out in 1 or 2 year:

During selecting behind the soil from the May to September, if press the 6-8 kilogram by the every square meter of preceding stubble plantation banker soil every square meter 4-6 kilogram or new land reclamation, the leaf of green grass and/or blue or green wealthy tree is plowed after the upper berth, ground is even, minimum turning over more than 15 times, degree of depth 30cm-40cm all turns over soil, ploughs at interval more than 2-4 days at every turn, When the Rain Comes will etc. ground done and turned over again, can not plough when wetting.

Repeatedly plough be for the ultraviolet ray that utilizes sunshine uniformly to the soil sterilization, green grass and/or blue or green wealthy leaf are sterilized to the soil, main effect is done in improvement;

(4) ginseng seeds selection and germination treatment are operated by said process, and (5) raising ginseng seedlings is operated by said process; Other process ginseng planting's technology is routinely operated (list of references 1. " panax ginseng in jiljn planting technology "; " ginseng cultivation technique " of list of references 2. Jilin Science Presses, the 1st edition (on December 1st, 2007)).

The advantage of level land plantation genseng:

1) economy of our country develops rapidly at present, and the national life level improves day by day, and is increasing to the health food demand.The selection ginseng planting soil of conventional ginseng planting patterns is that deforestation is fallen trees; national forest protection does not allow to haggle to have cut down forest; so the area of plantation genseng reduces day by day; plantation genseng in level land can remedy ginseng planting's area to be reduced, and also the genseng that was considered as the king of hundred grass in several thousand for China in people mind has been found out new planting environment.

2) plantation genseng in level land is fit to the large tracts of land development, easy standardized management, and traditional plantation genseng is because be the forest land plantation, and is too big to operation and transportation production materials needed aspect difficulty.Level land plantation genseng has changed these unfavorable factors, has improved operating condition greatly.

3) be 6 years the vegetative period of genseng, plant 20,000 yuans of every mu of infusion of financial resourcess, after 6 years every mu can gather in the crops 500-1000KG followed in present 6 years Jilin Area genseng ground procurement price be per kilogram 200-260 yuan plant genseng after 6 years common people can take on every mu of ground 100,000-260,000 RMB.

4) genseng mainly is grown between north latitude 34 degree-48 degree, and Donggang City is seated north latitude 40 degree has only sky to get thick soil, weather conditions.The west of Donggang City, the north to the most of plantation genseng that is fit in fertile sweat field.The ginseng planting can provide the new economic crops of plantation high added value for local common people, improves the peasant economy income.We try hard to be area, Donggang City are become new genseng production primary area in governmental leading official's support and under helping.

Embodiment

(1) soil is selected (2) land improvement (3) to mount the throne to take sunshade (4) ginseng seeds to select and germination treatment, (5) grow seedlings (6) select seedling (7) and plant transplantation of seedlings; (8) genseng field management;

One, the soil is selected: the area between north latitude 34 degree-48 degree;

1) the northwards broad or northeastward in the place ahead tilts or the level land needs only the good sandy loam of draining, all can more than the dark 30CM of soil layer;

2) genseng has unique abnormal reaction disease to soil, take the crop rotation soil and should need rotation cycle (not planting the soil of genseng in namely 10 years) more than 10 years, stubble plantation banker is corn before will selecting when selecting dry land ground, grass family such as wheat class or legume crop are for well, and the banker of planting other crops not quite is fit to the plantation genseng.

Two, the land improvement time is to carry out in 1 or 2 year:

During selecting behind the soil from the May to September, if press the 6-8 kilogram by the every square meter of preceding stubble plantation banker soil every square meter 4-6 kilogram or new land reclamation (reclamation of wasteland soil), the leaf of green grass and/or blue or green wealthy tree is plowed after the upper berth, ground is even, minimum turning over more than 15 times, degree of depth 30cm-40cm all turns over soil, ploughs at interval more than 3 days at every turn, When the Rain Comes will etc. ground done and turned over again, can not plough when wetting.

Repeatedly plough be for the ultraviolet ray that utilizes sunshine uniformly to the soil sterilization, green grass and/or blue or green wealthy leaf are sterilized to the soil, main effect is done in improvement;

Three, mount the throne and take sunshade (ginseng planting's technology is mounted the throne and taken sunshade operation routinely)

1) genseng happiness scattered light or skew ray, the high light direct projection has a strong impact on its growth, so set up sunshade one day 9 thirty to 15 a strongest direct projection light block, be skew ray and the good good utilisation of the scattered light on daytime sooner or later, so do the genseng bed direction, set up sunshade angle extremely important, the direction of ginseng bed is southeastern direction, and some difference of various places approximately becomes 25-30 degree angle to be the direction of ginseng bed with east;

2) the height 50-55CM of ginseng bed, wide 100CM apart from 100CM, stays the drain ditch between bed between bed; Take the high column of sunshade material requested 200CM, cross bar, puggaree or reed curtain, plastic foil, iron wire.

3) shelving.Side at each ginseng bed is taken column along ginseng bed direction, and column is followed closely into ground 40-50cm.Establish cross bar between the column of adjacent ginseng bed, cross bar two is ridden on the column, tie with iron wire.Before eaves (the north side column is preceding eaves) highly for 120cm, back eaves (the southern side column be the back eaves) highly is 75cm, preceding eaves delegation and after eaves one row distance be 200cm, guaranteeing that the front and back eaves is striden between a column becomes straight line.Be 200cm with delegation's column spacing.Cover on the frame with puggaree, tie with iron wire, use the sunshade net shading of shading rate 65% above.

Four, ginseng seeds is selected and germination treatment

1) genseng began to bloom in general 3 years, selected 4 years stranger's ginsengs in order to choose elite seed, and late May blooms and gathers after the maturation for 7 the end of month.Are the most healthy and the strongest periods of genseng 4 end of the year.

2) gather good genseng seed and remove pericarp and pulp as early as possible, use the clear water wash clean, the big grain that the full color and luster of screening fruit grain is fresh carries out germination treatment.

3) mesh bag that the genseng seed do not leak of at the beginning of 8 months the genseng seed of wash clean being packed into, charge weight is 30% of mesh bag volume, and sack is sealed, and adopts the granite stones of the wash clean of packing in the same mesh bag, and loading amount is 30% of mesh bag volume, and sack is sealed.

4) place the good bulk container of bottom discharge in the shady and cool ventilation benefit, the thick granite stones mesh bag of container bottom shop 15cm, tiling one deck genseng seed (5cm is thick) in the mesh bag of packing into above, spread one deck granite stones mesh bag (5cm is thick) above, fill container with this sequence alternate, topmost one deck is the granite stones mesh bag, topmost mesh bag build water permeable;

5) water every day in August once permeablely sooner or later, water once permeable every night in September, and 2-4 days October, early or water evening once permeablely all overturnings were once the order up and down of the ginseng seed mesh bag in the container in container for every interval 20 days;

During each overturning, to take out the seed mesh bag first day evening, being placed on the ventilation benefit allows it absorb natural wind, before sunrise in morning in second day, put in the container again, topmost the ginseng seeds bag is placed on container on one deck granite stones bag of beneath placement when taking out, ginseng seed mesh bag order reversing back from top to bottom is by using granite stones mesh bag intervening sequences to place from bottom to up in container during with taking-up, and this order is put into nethermost ginseng seeds bag and builds the granite stones mesh bag topmost.

6) obtain the good ginseng seeds of breach to 10 the end of month.In order to consider that residue of pesticide do not use agricultural chemicals, this ginseng seeds breach processing method can make ginseng seeds breach rate reach more than 80%.

Five, raising ginseng seedlings

1) cultivates good good people's seedling, it is the key that cultivates good high-quality genseng, in order to cultivate the best people's seedling, (aseptic earth is crossed the 20-40 mesh sieve and is got final product for the medicine soil that whole soil utilizations in nursery are prepared meticulously and selected aseptic fine earth, get down fine earth of sieve), not have river sand (the grains of sand of pollution, (1-3MM), with mass ratio 3: 8: 1: ratio is puddled and is evenly made.

2) prepare the medication soil soil of growing seedlings;

Mid-June, collection did not have 5 tons of contaminated mongolian oak leafs, 0.25 ton of rice chaff (being the rice chaff of paddy rice), 3.5 tons of cow dungs, 0.4 ton of charcoal charcoal ash;

First shop one deck (10cm is thick) leaf spreads one deck rice chaff and covers in leaf and get final product, and repaves one deck leaf (10cm is thick), spreads one deck rice chaff and covers leaf.Spread 1 meter high repeatedly, build with plastic foil, raise plastic foil overturning leaf after 3-4 days and cover plastic foil again, dry after 3 months leaves rot well fully repeatedly.

It is dark to dig 70CM, wide 1.5 meters, and length is by individual demand, and the bottom is completed with plastic foil and put into cow dung, builds the every 3-4 of plastic foil days overturning above once, and 3-4 dries after allowing it rot fully in individual month repeatedly.

Shine good leaf and cow dung, cow dung charcoal ash and mix the use of evenly growing seedlings.(1 mu of ground (namely 667 square metres) usage amount).

3) seed disinfection

The good ginseng seeds of breach is mixed all back airings to ginseng seeds with low-risk agricultural chemicals when suitable happy (), sows.1 kilogram of seed uses 5 milliliters of 2.5% suspending agents when suitable happy.

4) use the native soil of the medicine for preparing by high 0.25-0.3M, wide 1.00M carries out the ginseng bed of growing seedlings apart from 1.00M for every, and 2000 times of (volume) dilutions the when seedbed is suitable happy with 2.5% spill nursery bed disinfection.

5) build by 1.5-2CM thickness with sandy soil after utilizing sower to finish ginseng seeds, build the ginseng bed with film, build bed surface with straw straw is pressed.November sowing time, every square metre of seeding quantity 30g;

6) pass the winter to mid-April in the coming year, seed is sent out the tooth rate and is reached at 35% o'clock and build awning, film is taken out press straw and protected moisture, and the nursery drying is in time watered, and obtains seedling.

Six, select seedling

The genseng seedling will be selected the garden wing, and epidermis has not a particle of spot, broken skin a bit, and brood cell's complete form, color and luster is fresh, and slender have two legs, length 9-12Cm, per kilogram 400-500 is optimality criterion.

Seven, plant transplantation of seedlings

1) at the beginning of 34 months the end of month is ginseng transplanting's preferably period, the ground that improvement is good revolves that not have lump to press bed surface 1.00M wide, the genseng bed surface is apart from 1.00M, bed surface height 0.5-0.55M, standard carry out behind the ginseng bed by the bed surface width ditch, by become the miter angle degree to plant genseng with level, guarantee that ginseng bud is eastwards;

2) transplant every time ditch of density (being the wide length of bed surface 1.00M) and plant 6-9, every time distance is 10-20CM.The blinding degree of depth is seedling top 2-3CM, notices when planting ginseng that ginseng can not be crooked.

3) transplant back ginseng bed mulching straw in time, in order to prevent arid and stiff because of topsoil, people's seedling can't be unearthed.

Eight, genseng field management (ginseng planting's technology is carried out bookkeeping between ginseng nugrsery routinely)

1. weed with a hoe: on April, the middle ten days, when brood cell's cracking is upwards grown, throw off covering immediately, rake pine table soil, the flat furrow face of an animal-drawn seed plough.Will carry out between breeding time weeding with a hoe for 5～6 times, the 1st inferior to before emerging, and loosening furrow face table soil is abolished and hardened, to improve soil temperature, favourable emerging; The 2nd time at Qi Miaohou; The 3rd time before blooming; The 4th is in the first fruit phase; The 5th is carried out in the ripe front and back of fruit.To 6 years living seedlings, before will gathering in the crops, also must increase by 1～2 time and weed with a hoe, in order to improving output.Weed with a hoe at every turn, be sure not to hinder root and brood cell, otherwise influence output and quality.

2. defloration flower bud: in order to reduce meaningless nutrient consumption, when flower a kind of sedge is extracted out, in time extract whole buds, make nutrient centralizedly supply sage root growth, can improve genseng output and quality (except the plant of reserving seed for planting).

3. ridging: be positioned at the plant of the preceding eaves of furrow, because heliotropism causes cauline leaf to the furrow outgrowth, easily exposed to the sun and rain, and easily cause disease, therefore, plant should be pushed back in the cool canopy, must earth up at rhizosphere, and compacting.

4. topdress: behind the first tenday period of a month in the May neat seedlings, absorb the many positions of root in conjunction with weeding with a hoe in genseng and ditch widely 5 centimetres, absorb root degree of being to expose, be sure not to run into reed head and main root.Then, with liquid fertilizer (the lion horse that German Kang Piao company produces is green, and by specification uses) (or with 2% superphosphate solution, or 0.3% potassium dihydrogen phosphate, or 0.3% urea liquid fertilizer, or two kinds or three kinds be used alternatingly) pour into equably in the ditch, back to be infiltrated earthing is built solution.Especially to transplanting the seedling after 4 years, can promote root system development, robust growth is for volume increase lays the first stone.

The farmland plants ginseng ground, should impose to mix fertilely, executes 5 kilograms of the pig manures of becoming thoroughly decomposed, 0.25 kilogram of soya-bean cake, 0.5 kilogram of chicken manure, 5 kilograms of 0.1 kilogram of superphosphate and burnt dust-ashes for general every square metre.At the beginning of 5 months, carry out ditch spread in conjunction with weeding with a hoe.According to Jilin special product research institute test, in bud stage, flowering stage, fruiting period and before the beginning of autumn, in genseng foliage-spray 2% superphosphate liquid fertilizer (being top dressing), can make ginseng root volume increase 63%.

5. soil moisture management: the genseng happiness is moistening, not drought-resistant.Different age, the different developmental phases of joining, all inequality to the requirement of moisture.Therefore, must regulate soil moisture.In genseng breeding time, soil moisture content should be about 50%.The farmland plants ginseng can take man-made irrigation, or in the about 10 centimetres broad-leaved tree fallen leaves of ginseng bed furrow face cladding thickness, the time in 5 months, the last ten-days period, after seedling all sprouts, carry out in conjunction with loosening the soil, topdressing.

6. winter protection is survived the winter: genseng cold resistance is strong, causes " slow sun freezes " but be afraid of to freeze early spring one change most.Therefore, annual before freezing the Beginning of Winter around, in time go up anti-dry frozen ground, thick about about 10 centimetres, thaw when joining following 5 centimetres of root in next spring soil, remove anti-dry frozen ground.Also can around ginseng ground, set up anti-wind and snow barrier.

Level land of the present invention ginseng planting's success rate height, and product quality and economic effect are very good.
