Abstract

The invention discloses a method for quickly raising sapodilla seedlings by cutting. The method includes that field parcels with fertile soil are selected to be used as nursery fields, fertilizers mainly comprise farmyard manure, and 1000 kilograms of the farmyard manure, 50 kilograms of three-nutrient compound fertilizers, 50 kilograms of phosphate fertilizers and 100 kilograms of plant ash (or 10 kilograms of potassium sulfate) are applied to each mu of the nursery fields; the seedlings are raised in daylight greenhouses for winters, small arched sheds are fastened in the greenhouses, the temperature ranges from 24 DEG C to 28 DEG C under the control, ventilation is required when the temperature exceeds 30 DEG C, and the small arched sheds are used and mats additionally cover the seedlings for heat preservation when the temperature is lower than 0 DEG C; management operation such as soil loosening for nursery beds, watering, top application and disease and pest control needs to be effectively carried out. The method has the advantages that after the sapodilla seedlings are raised by the method, a cut strip seedling rate reaches 95% at least, and the seedlings are healthy and can leave the nursery fields after 20 to 25 days; the yield per mu can reach 2000 kilograms to 3000 kilograms after the seedlings are planted.

Description

A kind of rapid cuttage seedling-cultivating method of Fruit of Panax ginseng

Technical field

The invention belongs to the vegetable growing technical field, relate in particular to a kind of rapid cuttage seedling-cultivating method of Fruit of Panax ginseng.

Background technology

Fruit of Panax ginseng belongs to the Solanaceae nightshade, is a kind of natural highly nourishing health care fruit that is rich in various trace elements of introducing from South America.This fruit delicate fragrance succulence, both can eat raw, also can be used as that vegetables are decocted stir-frys, fry, the cold and dressed with sauce soup of doing, and also can be processed into can and beverage etc., and market prospects are had an optimistic view of.The major defect that at present the Fruit of Panax ginseng cuttage and seedling culture exists is that the nursery stock root of hair is slow, goes out the garden cycle long, the seedling cost increase.

Summary of the invention

The present invention is directed to the nursery stock root of hair existed in Fruit of Panax ginseng cuttage and seedling culture process slow, go out the garden cycle long, the problems such as seedling cost increase, provide the long root of a kind of nursery stock fast, the cuttage and seedling culture method that the seedling time is short.

Performing step of the present invention is like this:

1. nursery lot is selected: select physical features higher, irrigation and drainage are convenient, leeward facing south, the field of fertile soil.

2. the selection of cuttage stem branch: select the fresh and tender stem branch of high yield strain, disease-free, N/D, in order to the Sheng Xingenfa sprouting.The length of transplanting a cutting is advisable with 10-15 centimetre.Cutting after cutting off, insert in soil in time, otherwise should be placed on shady place or cover with wet cloth, in case dehydration.

3. the selection of fertilizer: (1) Fruit of Panax ginseng should not be to fertilize, the applications of farmyard manure of trying one's best.General mu is executed 1000 kilograms of high-quality farmyard manures, 50 kilograms of Nitrogen, Phosphorus and Potassium, 50 kilograms, phosphate fertilizer, 100 kilograms of ash (or potassium sulphate 10 kilograms).(2) when fertilising, farmyard manure should deep placement, and phosphate fertilizer can cover on farmyard manure, and mu executes 100 milliliters of phoxims, carries out soil treatment, with the control soil insect.

4. bedding wholely: first by soil deep ploughing, harrow brokenly, flatten whole carefully, accomplish without clod, lower to Wo Fa, defincienct in the upper and excessive in the lower, in order to cultivating strong sprout.Long general 8～10 meters of furrow, wide 1.5 meters, 20 centimetres of furrow ditch depths.

5. cottage propagation and seedbed management: (1) Fruit of Panax ginseng is bred with sun light green house winter, during to the Frost's Descent in autumn, the upright healthy and strong branch of choosing, be cut into 10～15 centimetres, insert in the furrow face, bury 3～4 centimetres, distance between rows and hills is 5 centimetres of 7 cm x, water immediately after inserting, do not want lack of water in 7～10 days, in order to alive.(2) carry out seedbed management after living, intertill and clean tillage, topdress, water, and prevention and elimination of disease and pests etc.Getting hold of greenhouse temperature and operational procedure, is the Fruit of Panax ginseng successful key of growing seedlings.Otherwise, will lead to the failure.The Fruit of Panax ginseng preference temperature is 24～28 ℃, and surpassing 30 ℃ will ventilate; When temperature drops to 0 ℃, detain small arched shed and add a cover straw screen or mat with insulation in booth.(4) fine day was taken off film at 9 o'clock in the morning, is taken off straw screen or mat, at 3 o'clock in afternoon overlay film, cover straw screen or mat, be conducive to carry out photosynthesis, increase fruit seedling chlorophyll.(5) can take the circumstances into consideration to loosen the soil, water, topdress, the pipe work of a series of field such as the anti-worm of curing the disease.(6) after spring has set in, temperature rises gradually, takes off film daytime, takes off straw screen or mat, and evening, overlay film, do not cover straw screen or mat.When the canopy temperature rises to more than 5 ℃, small arched shed is thrown off (favourable hardening) entirely.(7) for cultivating strong sprout, answer spray plant growth regulator, short weak seedling turns strong sprout, and Huang Ye becomes greenery, controls prosperous seedling to turn strong sprout, in order to transplanting land for growing field crops early spring.

6. the extermination of disease and insect pest: Fruit of Panax ginseng damage by disease and insect in winter has aphid, two spotted spider mite, little leaf, leaf-curl, leaf curl.Anti-eliminating aphis mainly sprays with pyrethrin pesticide, as beta-cypermethrin, and decis, Belmark, forbid with Rogor class pesticide control (the Rogor class has destructive poisoning to Fruit of Panax ginseng).The control two spotted spider mite, available 34% superpower 3000～5000 times of liquid of mite emulsion for cleaning of sweeping, 2000 times of liquid of Dicofol emulsion.Prevent and treat little leaf, leaf-curl, available zinc fertilizer, 200 times of liquid foliage-sprays of high-efficiency boron-magnesium fertilizer 2～3 times.Leaf curl sprays 1～2 time and gets final product with plant greenery king, bio-bacterial manure, green rich 95.

Adopt this method to cultivate the Fruit of Panax ginseng seedling, skewer bar planting percent reaches more than 95%, the nursery stock stalwartness, and 20---within 25 days, can go out garden.After seedling growth, 2000～3000 kilograms, per mu yield fresh fruit.

Claims

1. the rapid cuttage seedling-cultivating method of a Fruit of Panax ginseng is characterized in that: adopt the winter sun light green house to grow seedlings, control 24～28 ℃ of greenhouse temperatures, surpassing 30 ℃ will ventilate, and during lower than 0 ℃, adds the button small arched shed and add a cover the straw screen or mat insulation in canopy.
