Description

A kind of diseases and pests controlling method of green soy bean

Technical field

The present invention relates to proportion of crop planting field, particularly a kind of diseases and pests controlling method of green soy bean.

Background technology

Green soy bean nutritive element content enriches, and being called as green soy bean at the fruit maturation initial stage, is the seed of Papilionaceae plant soybean, annual herb crops, high 30 ~ 90 centimetres, sturdy, the square rhombus of stem; The yellow elongated bristle of close life in pod rectangle, pancake, long 5 ~ 6 centimetres, sagging, pod; 2 ~ 4, seed, fresh time flat ellipticity oval, long 0.8 ~ 1.5 centimetre, light green, dry time yellow, yellow green or atropurpureus.Spring, green soy bean and Fresh edible soybean, also claimed green soy bean, green soy bean, white green soy bean, referred to the blue or green pod soybean variety gathered in the crops between seed drum expiry to first ripe phase, beanpod peak green, verdant lovely.It is exactly the soya bean that we are familiar with after green soy bean is aging.

But, green soy bean diseases and pests controlling is the significant problem of puzzlement wide farmers always, the sick worm of green soy bean generally has rust, downy mildew, aphid, two spotted spider mite, lima bean pod borer and large Grapholita spp etc., and the current Main Means for green soy bean diseases and pests controlling is exactly large-area spraying insecticide, to such an extent as to green soy bean exists residue of pesticide really, the requirement of present people for pollution-free food can not be met.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of diseases and pests controlling method of green soy bean, the use of agricultural chemicals is stopped in green soy bean growth cycle, meet the requirement of present people for pollution-free food, reduce the generation even eliminating sick worm in green soy bean growth cycle, improve the quality of green soy bean ripening fruits.

For achieving the above object, the diseases and pests controlling method of a kind of green soy bean that the present invention proposes, it comprises the steps:

One, in the seed treatment stage: select 2% sodium hydroxide solution to soak seed 30 minutes, pull rear clear water out to clean, then soak seed 60 minutes in seed insecticide, presoaking and germinating again, seed insecticide is the solution of coptis extract, extractive of perilla, triperygium wilfordii extractive and water composition, and coptis extract, extractive of perilla, part by weight between triperygium wilfordii extractive and water are 1:2:1:10;

Two, in the whole ground stage: before whole ground, treat sowing soil and carry out cover type water logging 24 hours, then carry out wholely, the soil after completing as being exposed to the sun under burning sun 12 hours wholely;

Three, sowing stage: to the sterilization of canopy chamber surface and nursery soil sterilization before sowing, the sterilization of canopy chamber surface selects ozone and 20% Mobucin fumicants to carry out compound fumigation; 20% athomin aqueous emulsion drip irrigation is selected in nursery soil sterilization, also medicine seedlings and soil can be adopted, mould clever wetting powder 8 grams is disliked for every square metre with 50% carbendazim or 30%, mix with appropriate fine earth and spread fertilizer over the fields, adopt the medicine soil 1/3 prepared of getting of conventional Cold frame to be sprinkling upon on bed surface or in seed furrow, more remaining 2/3 medicine soil is sprinkling upon on the seed that finished, effect is better, but keep bed surface table soil moistening, prevent poisoning; After having sowed, silver grey film is covered to seedbed;

Four, seedling stage: seaweeds, plant immune protein, during 3cm-10cm, are diluted 1000 times, spray seedling plants by seedling height, seedling plants height, when 12cm, a strain feverfew is planted in every square area in seedbed;

Five, yield positive results the stage: in whole green soy bean growth cycle, protection is conducive to the Vegetation condition of natural enemy existence, from plant height 12cm, can put frog in a suitable place to breed in right amount to seedbed, every mu of seedbed release is not less than 100;

Six, the critical developmental stage: by Flos Daturae extract, RADIX ACONITI KUSNEZIFFII extract, Radix Gentianae extract, coptis extract, extractive of perilla, triperygium wilfordii extractive, chrysanthemum cinesariaefolium extract obtaining liq insecticide by weight proportion, wherein each material proportion is respectively: 2:1:1:2:3:2:5, by after the solution dilution 1200 times of joining, green soy bean plant is sprayed, always from green soy bean plant from 10cm high be sprayed to green soy bean gather before 1 week, spray frequency be every 7 days spray once.

The diseases and pests controlling method of a kind of green soy bean proposed by the invention, stops the use of agricultural chemicals in green soy bean growth cycle, meet the requirement of present people for pollution-free food, reduces the generation even eliminating sick worm in green soy bean growth cycle, improves the quality of green soy bean ripening fruits.

Embodiment

A diseases and pests controlling method for green soy bean, it comprises the steps:
