Abstract

The invention provides a cultivating method for organic Chinese chives. The cultivating method comprises the following steps of: cultivation land soil pre-treatment of removing live soil on a surface layer, deeply plowing the land, adding a soil degrading agent, mixing castor-oil plant straw crushed aggregates in the soil, and covering a shed for sterilization before transplantation; fertilizer selection of adopting organic raw materials such as livestock, livestock manure, crop straws, and fermenting the organic raw materials into a microbial organic fertilizer; water irrigation of adopting underground water of a deep well 60 meters below the ground or natural spring water; pest control of adopting any one or any two of the following methods, including, hooding a fly net above a planting section of the organic Chinese chives, extracting liquid from the castor leaves, drying the castor leaves in the sun, grinding the castor leaves into powder and doping with soil for application, adding water 5 times castor pomace into the castor pomace, stirring and extracting for 12 hours, filtering and removing the pomace, spraying the obtained extracted liquid on the leaves of the Chinese chives at dusk of a sunny day, using the medical liquid of 20-40 kg per each mu, and arranging a castor-oil plant planting isolation zone around the organic Chinese chives planting field. The cultivating method for the organic Chinese chives can meet with growth need of the Chinese chives, achieves high yield of the Chinese chives, prevents plant diseases and insect pests efficiently, keeps ecological balance of the soil, and is conductive to environmental protection.

Description

A kind of breeding method of organic Chinese chives

 

Technical field:

The present invention is a kind of breeding method of organic Chinese chives, belongs to vegetable growing.

 

Background technology:

Leek is that people are than preferable vegetables, edible part is mainly blade, leek is warm in nature, and taste is pungent, has kidney tonifying and plays sun effect, contain the special composition such as volatile essential oil and sulphide, give out a kind of pungent fragrance taste of uniqueness, contribute to dredge and adjust irritability, improve a poor appetite, strengthening digestive function, is a kind of vegetables wide, amount is larger that eat.。Tradition plantation be take land for growing field crops leek as main, is generally subject to the harm of fragrant-flowered garlic maggot, root-knot nematode in production process, causes the underproduction, poor quality, therefore vegetable grower uses agricultural chemicals to prevent and treat, and uses in a large number agricultural chemicals, even uses high residue highly toxic pesticide, cause residue of pesticide rich long-pending in soil, be detrimental to health.Carry out in recent years pollution-free leek production technology, forbid high residue highly toxic pesticide, use high-efficiency low-toxicity less-persistent pesticide, standardized planting technology, but often detect residue of pesticide and do not reach pollution-free leek standard-required, because the leek production cycle is gathered in the crops one batch of only 20-30 days season in vigorous growth, once need to use agricultural chemicals adding often to cut, sometimes dispenser is delayed, and causes the pollution-free leek standard that do not reach.Want to produce green agricultural product and must change traditional planting technology.The farmyard manure that tradition is used can not meet the needs of leek growth to nitrogenous fertilizer, therefore yields poorly, and easily causes many damage by disease and insect, causes the excessive of fertilizer and pesticide to be used.In addition, the employing of inorganic instant nitrogenousfertilizer, not only can bring soil compaction, spoiled soil ecological level and smooth, pollute the drawbacks such as natural environment, and have a strong impact on the quality of leek product, excessive inevitable generation medicament residue, the infringement leek quality used of agricultural chemicals.Make to adopt leek breeding method of the prior art, the leek of production is difficult to reach the technical standard of organic products.The edible crowd's of harm health.

 

Summary of the invention:

The object of invention is to avoid above-mentioned weak point of the prior art, and provides a kind of fertilizer efficiency nutrient component comprehensive, can meet leek growth demand, and leek output is high; Effectively pre-preventing disease and pest occurs, and keeps soil ecology balance, favorable environment protection; The leek producing meets the breeding method of the organic Chinese chives of organic products specification requirement.

The breeding method of organic Chinese chives of the present invention, comprises the steps:

A. milpa soil pretreatment: remove the top layer soil of living, soil deeptillage, adds Soil degradation agents; In soil, sneak into castor-oil plant crushed straw aggregate; Button canopy sterilizing before transplanting;

B. fertilizer is selected: adopt the organic matter materials such as domestic animal, poultry manure, agricultural crop straw, be fermented into microorganism organic fertilizer;

C. irrigation water: adopt 60 meters of following deep-well underground water or springwaters;

D. the extermination of disease and insect pest: a kind of or its any two or more combinations in adopting with the following method: cover fly net above organic Chinese chives plantation location; Castor bean leaf aqueous extract; Castor bean leaf is dried and mixes soil after levigation and use; Castor pomace is added to 5 times, water, under stirring, extract filter and remove residue 12 hours; Gained extract selects fine day during dusk, to spray leek blade face, and every mu with 20 ~ 40 kilograms of liquids;

E. in organic Chinese chives plantation field, be provided with cultivating castor-oil plant isolation zone around.

 

embodiment:

The breeding method of organic Chinese chives of the present invention, comprises the following methods of cultivation and management process:

A. milpa soil pretreatment

1. remove top layer and live native 11 centimetres

2. soil deeptillage is 31 centimetres

3. add Soil degradation agents appropriate (the fertility bacterium that Beijing Yi Kele Eco Science Technology Co., Ltd produces), 5-6 kg/acre

4. in soil, sneak into castor bean crushed straw aggregate

5. before transplanting, button canopy carries out high-temperature sterilization for 20 days;

B. fertilizer is selected

Employing is with domestic animal, poultry manure, agricultural crop straw, and agricultural byproducts processing waste residue, brewery industry waste residue and sugar industry waste residue are organic matter material, add microbial bacterial agent, the microorganism organic fertilizer of the organic Chinese chives special use that heap fermentation forms.

The microorganism organic fertilizer of described organic Chinese chives special use comprises the following raw material components in weight fraction: organic matter material 900, fused calcium magnesium phosphate 50, microbial bacterial agent 1, brown sugar 2; The agent of described microorganism Jun is the commercially available complex micro organism fungicide that contains saccharomycete, lactic acid bacteria, actinomycetes and high temperature bacillus.

C. irrigation water

Adopt 60 meters of following deep-well underground water;

D. have no side effect. the extermination of disease and insect pest

Combination in adopting with the following method:

1. above organic Chinese chives plantation location, be covered with fly net, reticular density 30 orders, every 0.8 mu builds a fly net;

2. castor-oil plant cotyledon aqueous extract

Its extracting method is: castor bean leaf is ground to pulping, add 3 times, water, soak and extract 12 hours, filter and remove residue; Extract sprays leek blade face; The castor bean dregs of fat can also be added to 5 times, water, rub and soak 12 hours, select fine day to spray during dusk while using, every mu with 20 kilograms of liquids;

3. castor bean leaf is dried and mix soil after levigation and use;

4. the castor bean dregs of fat are added to 5 times, water, under stirring, extract filter and remove residue 12 hours; Gained extract selects fine day during dusk, to spray leek blade face, and every mu with 20 kilograms of liquids;

E. in organic Chinese chives plantation field, be provided with castor bean plantation isolation zone around.Described isolation strip sector width is 5 meters.
