Description
Technical field
The present invention relates to pesticide production technology field, it particularly relates to which a kind of utilize " print chinaberry fruit " production noresidue agriculture
The preparation method of medicine.
Background technology
Existing pesticide species are more, there is agricultural chemicals chemically and vegetal agricultural chemicals, though agricultural chemicals chemically has preferably
Insecticidal properties, but some compositions in agricultural chemicals are difficult to decompose, and can remain on plant, and the part for being difficult to decompose generally contains
There is the toxin unfavorable to human body, such as most of phosphorous agricultural chemicals can be all remained on plant, when these agricultural chemicals are used for into vegetable
During dish fruit, the health of human body can be damaged.Vegetal agricultural chemicals relative toxicity is smaller, but most of vegetalitas agriculture
Medicine insecticidal effect is not good enough, and botanical pesticide raw material is not easy to obtain, and real non-harmful botanical pesticide is also few.
It is Meliaceae Melia arbor to print chinaberry, and print chinaberry is the preferable pesticide plant generally acknowledged in the world at present.Nimbin is a kind of
Highly oxidized citrin, with many similar functional groups.AZ-A was once isolated from neem seed to the activation of AZ-G7 kinds
Compound, wherein A are main insecticidal constituents.Print chinaberry originates in India and Burma, plants extensively in tropical and subtropical region,
Southern Asia, Africa and more than 70 countries of South America have been distributed, the wild fairly large distribution of print chinaberry fruit in Anshun Prefecture.
Nowadays print chinaberry product such as nimbin have in terms of crops deinsectization is widely applied very much.Azadirachtin preparation is applied to soil
Earth, it can be absorbed by crop roots such as cotton, rice, corn, wheat, broad beans, be transported to cauline leaf, resisted so that whole plant has
Worm property.Chinaberry product is printed in addition to insecticide is made, also multiple use, contain in its seed and kill nematode, sterilization and antiviral activity
Composition.Nimbin content highest generally in chinaberry fruit is printed, but in nimbin extraction process, because the presence of nim oil is to extraction
Nimbin brings bigger difficulty, if first nim oil is squeezed out to come, high temperature can decompose nimbin, if first print chinaberry fruit
Crush, then due to the presence of nim oil, the easy conglomeration of crushing process, hinder the progress crushed.
The content of the invention
In view of this, it is an object of the invention to provide it is a kind of using print chinaberry fruit production nonpersistent pesticide preparation method, with
Solve in nimbin extraction process, because the presence of nim oil brings bigger difficulty to extraction nimbin, if first print chinaberry
Oil pressure, which is squeezed out, to be come, then high temperature can decompose nimbin, if first that print chinaberry fruit powder is broken, due to the presence of nim oil, crushing process
Easy conglomeration, hinder the progress crushed.
The present invention solves above-mentioned technical problem by the following technical programs：
A kind of preparation method using chinaberry fruit production nonpersistent pesticide is printed, comprise the following steps：
(1) pre-process：First will print chinaberry dried fruit it is dry to its moisture be 3~7%, then will print chinaberry fruit powder it is broken, chinaberry powder must be printed；
(2) extract：Print chinaberry powder is put into the digester equipped with water, after 3~5h of extraction at a temperature of 80~100 DEG C,
Filter residue is filtered out, obtains extract；
(3) concentrate：Extract is condensed into paste, produces agricultural chemicals.
The drying is that print chinaberry fruit is placed under solar irradiation to dry.
The drying is that print chinaberry fruit is placed in drying plant to dry.
The fineness of the print chinaberry powder is 30~40 mesh.
The mass ratio of the print chinaberry powder and water is 1：(4~6).
The density of the paste is 1.1~1.5g/cm3。
Application method 1：Paste is mixed to be filled with water and is sprayed on plant.
Application method 2；Paste is crushed and dried, solid powdery, which sprays or is watered, to be made the aqueous solution and sprayed water.
The deinsectization principle of agricultural chemicals prepared by the present invention：Using gas molecule deinsectization mode deinsectization, smell causes worm not eat food,
Reduce food-intake, the characteristics of worm does not breed, the decay period of worm is elongated.
The beneficial effects of the present invention are：
First, the present invention will be after print chinaberry fruit drying by that will be ground into coarse powder, increase during follow-up extraction processing print chinaberry fruit with
The contact area of water, be advantageous to improve the leaching rate of the nim oil and nimbin in print chinaberry fruit；
Secondly, nim oil is extracted, printed by the way that print chinaberry fruit powder is carried out into extraction processing by the present invention in the lump with nimbin
Chinaberry oil has the function that enhancing nimbin insecticidal effect, can substantially reduce the dosage of nimbin, and nim oil can also be to printing chinaberry
Element plays preferable protective effect, in addition, passing through the control to temperature during extraction process and time so that the leaching rate of nim oil
Reach more than 85%, the leaching rate of nimbin reaches more than 96%.
Again, the agricultural chemicals that prepared by the present invention has does not add any commercial synthesis chemistry without defective material thing, the nuisanceless, agricultural chemicals
The advantages of article.
