Abstract

The invention discloses a greenhouse seedling method for Astragalus membranaceus. The technical scheme includes the following steps: selection and preparation of a seedbed land, seed selection and seed treatment, sowing and growth management, transplanting and management, harvesting and processing management. The beneficial effect of the method are that: through a greenhouse nutrient soil bowl seedling manner, the problem that seedling cannot be performed due to a sharp diurnal temperature difference in a northwest region while the Astragalus membranaceus is planted can be solved; the growth period can be prolonged, the survival rate of the seedlings of the Astragalus membranaceus can be greatly improved, and the survival rate reaches 99%; and the Astragalus membranaceus can be planted in large area without seedling recovering, and the economic benefits can be increased.

Description

A kind of Radix Astragali seedling in greenhouse method

Technical field

The present invention relates to and belong to field of plant cultivation, be specifically related to a kind of Radix Astragali seedling in greenhouse method.

Background technology

The Radix Astragali is pulse family perennial herb, originates in the ground such as northeast, North China.It is used as medicine with root, has the function of invigorating QI to consolidate the body surface resistance, inducing diuresis to remove edema poison holding, granulation promoting.There are Radix Astagali and Radix Astragali, are certified products.The Radix Astragali is phreatophyte, and main root is long 20-80 centimetre.The nice and cool weather of happiness, drought-enduring cold-resistant, To Be Protected from Heat is afraid of flood, wild dries hillside fields on the sunny side in grassland, and germination does not like high temperature, and 14-15 DEG C is germination thermophilic.Germination and seedling stage need adequate water, otherwise do not emerge or arid and dead.Late May at Radix Astagali florescence, really late June phase to mid-July；Late June at Radix Astragali florescence, really August phase to mid-September.The unsuitable overdrying of full-bloom stage soil, in order to avoid fruit drop, seedling is thin and delicate, is afraid of high light, slightly covers, it is easy to survive, and adult plants and trophophase like arid and sufficient sunlight.

Chinese medicine plant is an approach of getting rich of peasant, and along with the development of China's medicines and health protection cause, increasing people will put into Chinese medicine and produce.In order to obtain the high yield of Chinese crude drug, high-quality and high benefit, owing to planting the Radix Astragali in northwest, due to cold weather, the Radix Astragali can not be met plant the environmental requirement of nursery, it is necessary to transport Radix Astragali Seedling from other places, cost is high, survival rate is low, benefit of planting is low, and can not large area plant because the time of planting is short, need to delay the problems such as Seedling, has had a strong impact on the development of the industry of planting.

Summary of the invention

It is an object of the invention to provide a kind of Radix Astragali seedling in greenhouse method, solve the Northwest plant because day and night temperature is big the Radix Astragali can not the problem of nursery, in order to improve survival rate, extend and plant the time, it is not necessary to slow Seedling, large area is planted, and increases economic benefit.

For achieving the above object, the technical solution used in the present invention specifically below:

1, seedbed ground selection and arrangement

Ground, seedbed: selecting soil property rich in humus, physical features is smooth and the convenient plot of irrigation and drainage；Require to seedbed last year or then the beginning of spring time build booth；The site preparation and fertilization on ground, seedbed: rake pine table soil before sowing, makes multiple furrow and waits to broadcast, use sufficient ammonium phosphate 30-40kg, potash fertilizer 20-30kg, fertilizer l-2t to every 1 mu of seedbed, form putting nourishing earth in stoup with rural area soil mixing and stirring after raking；

2, seed selection and seed treatment

Seed selection: adopt 3 years raw normal matures, without going mouldy without disease pest, preserving good seed；

Seeds preprocess: sow the previous day, the seed chosen adopts flowing clear water soak 48-72 hour, take out air-dry after, freezing at the temperature of subzero 15 DEG C to subzero 10 DEG C, 24-36 hour, carbendazim or the root 'qifuling ' powdered agent 5g of rear every lkg seed employing 50% dressed seed；

3, sowing and growth management

Select sowing time late April-early June, each dress nutrient soil pot is sowed the 1-3 grain seed after seed dressing, the degree of depth that every seed is broadcast by pressure is 0.3-0.8cm, then covers black thin film to its heat and moisture preserving；When Radix Astragali Seedling grows true leaf, by the control temperature of shed that leaks informaton 16-32 DEG C of scope；Dormancy autumn and winter is fallen between seedling stage, carries out booth temperature control；

4, transplant and manage

In the beginning of spring in next year, remove overcover, according to the management by methods of First Year, the Radix Astragali Seedling of germination is transplanted.Furrow width l00-120cm, the deep 5-8cm of furrow and furrow spacing 12-18cm.When Radix Astragali height of seedling is about 4cm and grows 4-5 sheet true leaf, every mu of mixture adopting 40% phoxim 40ml and 45kg water sprays killing insect pest by Sprayable, every preventing and treating in 7 days once, sprays 2-4 time continuously；

5, gather and management processing

Within after planting the 2nd year, blossom and have seeds.When the sagging yellow maturity of fruit pod, seed becomes sepia and can gather.Seed maturity differs, should with ripe with adopting.As gathered late, fruit pod cracking, seed shattering.Fruit pod dries threshing after gathering, and removes impurity storage standby.Radix Astragali after planting 2-3 gathers, and Radix Astagali 3-4 gathers, and autumn, overground part Huang was gathered in the crops after withering, and first cuts off plant on the ground, is then dug out by root, deep-cut, it is prevented that dig break taproot and damage crust.Can digging from one, ground, dig out section, carry out overturning.After root digs out, remove earth, take advantage of rhizome under fresh-cut (reed head), fibrous root, shine under sunlight to half capable person Gen Li and be directly bundled into handle, then shine or dry Radix Astragali.Finished product puts aeration-drying place storage.General mu receives dried food and nuts 150-250 kilogram.

The beneficial effects of the present invention is the seedling raising manners adopting booth nutrient soil pot, solve the Northwest plant the Radix Astragali because day and night temperature is big can not the problem of nursery, not only extend trophophase, substantially increase the survival rate of Radix Astragali Seedling, and without slow Seedling, large area can plant, add economic benefit.

Detailed description of the invention

The invention will be further described in conjunction with the embodiments.

Example 1, a kind of Radix Astragali seedling in greenhouse method adopt technical scheme specifically below:
