Description
Technical field
The present invention relates to a kind of breeding method of annual multi-branched Dwarf rootstocks apple seedling.
Background technology
European countries (Holland, France, Italy) Dwarf rootstocks apple nursery stock is bred, and adopts knip (cutting back) technology, mostly cultivates the multi-branched Dwarf rootstocks apple seedling of life in 2 years.1st year, after Dwarf rootstocks seedling is adopted back, spring is in vitro grafting (whip graft) apple variety in indoor, presses seeding row spacing 0.9 × 0.33 meter after healing March ~ April, transplanted and cultivated to nursery, land for growing field crops, can grow to 1.2-1.5 rice then, but not go out garden.Second Year early spring, retain clip blastogenesis long, shaping in garden, the year end went out garden in apart from 0.7-0.8 rice cutting back, ground (Knip).The indoor in vitro grafting in the 1st year of this technology adopts grafting technology, technical difficulty is large, needs larger place, and connecing rear healing needs certain facility, add grafting to take a lot of work, the Dwarf rootstocks seedling field planting after Grafted Variety is also lower by more than 10% than the direct planting survival rates of Dwarf rootstocks seedling in nursery survival rate.Add seedling height when kind growth fraction then directly plants stock and want large, easily lodge, so be the slotting vertical rod of each young plant immediately after field planting, take a lot of work." wiping out spire method " weak effect in branch technology, can only determine industry 3-5 the branch in early stage after doing in the 2nd of seedling growth year, would not produce desirable branch later; Concrete formula and the details of operation of " spraying general Lip river Malin (Promalin) method " are all secrecy technologies abroad, and we are unknown.The domestic a small amount of Dwarf rootstocks apple seedling produced at Shaanxi plain boiled water, although be also the annual Dwarf rootstocks apple seedling going out garden for 2 years, is all go alone seedling, and without branch, result is late.
At present, crab apple produce in newly-built garden substantially select that plant then can the short anvil high-quality seedlings of result, get final product Buddhist nun garden seedling (Knip boom, Dutch knip is the meaning of cutting back, boom is the meaning of sapling, knip boom refers to the sapling through cutting back shaping in garden, and being translated as temporarily can Buddhist nun garden seedling).The raising technology of this nursery stock is that Holland is pioneering, and its mating system is, April in spring by the Dwarf rootstocks apple seedling field planting of grafting in vitro in indoor in nursery, retain a scion variety bud germination and growth, about current growth to 1.5 meter, but do not go out garden.Second Year retains clip blastogenesis long in apart from 0.7-0.8 rice cutting back, ground (Knip) early spring, and adopt short branch technology, shaping in garden, goes out garden multi-branched seedlings the year end.
Dwarf rootstocks seedling is bred by horizontal press strip method.The Dwarf rootstocks seedling of breeding was gathered in the crops, is preserved before autumn and winter or rudiment in spring.Spring indoor branch-grafting apple variety, healing (about needing January) after in nursery field planting, seeding row spacing 0.9 × 0.33 meter.Be that each young plant inserts a vertical rod, by the young sprout gradation bondage of grafting pumping then in vertical rod, to guarantee sapling vertical growth immediately after field planting.The First Year cultivated in garden, young sprout can grow to 1.2-1.5 rice, but can't go out garden.In the Second Year spring, cut in 70-80 centimeters by this seedling and cut (Knip), concrete height can be determined according to the requirement of user, and this cutting back place diameter should reach 1 centimetre.Keep the first bud vertical growth after germinateing, remove other rudiment at any time at whole Growing season, make 70-80 centimetre of cutting back sentence lower maintenance smooth.Can all come from upright young sprout then by the Buddhist nun garden all side shoots of seedling, first side shoot distance ground 0.9-1.0 rice, when namely clip bud young sprout grows to 20 centimetres, pumping first second branch.One-level seedling will ensure to have the side shoot of 7 length more than 30 centimetres at least, usually at about 10.Substantially need not prune in the 2-3 of such nursery stock after the field planting of orchard, nearly all side shoot all can be used for result.In garden, the key of shaping how on raw young sprout then, inspires second branch, to form enough side shoots.Three kinds of methods are had to inspire second branch at present:
(1) spire method is wiped out: when 15-20 centimetre is grown in clip first blastogenesis, pinch or wipe out the first half of the spire that young sprout top is launched not yet completely, specific practice is that left hand thumb and forefinger pinch young sprout top, make female nail cover a little more than young sprout growing point, expose the first half of top spire, pinch by hand thumb first simultaneously or wipe out this part spire with little scissors, ensureing not injure young sprout growing point.Like this can past release young sprout top to the suppression of lateral bud, make lateral bud sprout into second branch very soon.Method is weekly like this, if young sprout growth is very fast, also can 3-5 days once, connect and be 4-6 time.
(2) spraying general Lip river Malin (Promalin): general Lip river Malin, containing the GA4+7 of the 50% and 6-BA of 50%, can promote the sprouting of young sprout lateral bud.Spraying when general young sprout grows to 15-20 centimetre, only spray once, often with wipe out spire and be combined.General Lip river Malin's working concentration is 2.5-5%, adds a little spreader-sticker.With manual sprayer young sprout top of respraying, top wet even have lower of drop till.
(3) spraying 6-BA: a spraying 6-BA also can promote sprouting of lateral bud.When clip bud pumping young sprout grows to 15-20 centimetre, start spraying, concentration is every 100 liters and contains 30-60 gram of 6-BA active ingredient, adds a little spreader-sticker.Spreader-sticker wants appropriate, do not add or very little then liquid can not be attached on the spire of band hair, spire of likely burning too much.Once in a week, spray 4-6 time is connected.In fact be also only spray 1-2 time and with wipe out spire and combine and can obtain better effect.
Newly slightly will note spreading angle at any time at Growing season to the secondary inspired, to control the growth rugosity of side shoot, promotion part becomes colored then.Final formation within 3 years, take root be, Dwarf rootstocks apple nursery stock that 2 years raw trunks, 1 Nian Sheng center dry doubling raw 6-12 secondary side shoot.
Existing external short branch technology, needs to grope detailed working specification, and these aspect Holland, France, Italian nursery stock company technique are maintained secrecy.
China is apple production state maximum in the world and country of consumption, the Apple Culture gross area 3090.3 ten thousand mu in 2012, gross yield 3849.1 ten thousand tons (China Statistical Yearbook in 2013), accounts for 42.54% and 48.44% of world's apple gross area and gross yield respectively.The advantage of scale of China's Apple Industry is fairly obvious, but yield per unit area, fruit total quality also have larger gap with orchard economic benefit compared with world's apple advanced production country, and cause this gap major reason to be China's Apple Culture system and technology mode backwardness.China's apple developed on a large scale period in the eighties in last century and the beginning of the nineties, main popularization be tall anvil planting culture pattern, the orchard of current China 90% is set up according to this cultivation mode, only have the orchard of 10% to adopt dwarfing interstock to build garden, and Dwarf rootstocks orchard is less than 0.1%.Although this kind of cultivation mode contributes to the Apple Industry fast development of promotion China, but because orchard worker grasps and unreachable position tall anvil planting culture technology, in addition the defect of this pattern self, causes that most of orchard is airtight, illumination is bad, result is late, yields poorly, fruit quality is poor.
Short anvil intensive culture is developing direction and the trend of world's apple production.The cultivation of apple dwarf interstock is the principal mode of China's apple dwarf cultivation at present, has played important effect aborning.Compared with dwarfing interstock apple seedling, Dwarf rootstocks apple seedling is bred in whole process and is not used true seed to sow, and seedling growth individual difference is little, neat and consistent, and Jian Yuan garden looks are neat, and early, output is high, quality better for result.Apple production developed country of the world (as the U.S., France, Italy) extensively adopts apple dwarf from the cultivation of root anvil, the orchard establishing of application Dwarf rootstocks apple seedling, and short anvil apple accounts for the apple gross area more than 90%, and export volume accounts for always produces more than 30%.
Apple in Shaanxi province area under cultivation and the gross yield whole nation first.Apple orchard area 997.83 ten thousand mu in 2013, apple gross yield 942.82 ten thousand tons (2013 Shaanxi Province fruit industry statistical communique of development), accounts for 30% of national total area, 25% of gross yield.Although be the large province of apple, be not that apple production is economized by force, with the plantation level in Shandong and per unit area yield gap larger; Gap is larger compared with apple production developed country of the world.Main cause is that Shaanxi Apple area is large, and the intensive efficient orchard area of short anvil is little, and science and technology demonstration and promotion rate are unable to catch up with apple area and are gathered way.In order to improve the international competitiveness of apple in Shaanxi province, promote Apple Industry upgrading, in recent years, Baoji, Shaanxi province city Qianyang County general first introduces European multi-branched Dwarf rootstocks apple seedling and builds garden, sets up Dwarf rootstocks propagation by layering garden, obtains good effect.
