Description
Technical Field
The invention belongs to the field of pesticides, and particularly relates to a slow-release pesticide-fertilizer composition.
Background
Molasses is a by-product of the sugar industry, a sticky, dark brown and semi-fluid object. Molasses contains a large amount of beneficial substances such as sugars, amino acids and proteins, and molasses also contains a large amount of minerals such as potassium, sodium, magnesium, calcium, phosphorus, etc. Molasses may be classified into liquid molasses and solid molasses according to their forms, wherein the solid molasses includes pure solid molasses and solid molasses containing other carriers prepared by carrier adsorption. Molasses is one of main byproducts in the sugar industry, and the molasses is mainly used as animal feed, a fermentation raw material in the alcohol industry and the like at present, so that the molasses is single in use.
The diatomite is a biological sedimentary rock with diatom remains as the main constituent of SiO2Mainly, the distribution is wide, and the distribution is in China, Denmark, America, Japan, France and other countries. The diatomite reserves in China are abundant and are distributed in Yunnan, Sichuan, Shandong and other provinces. Diatomite is a good adsorption carrier, but the diatomite has large difference in properties from place to place. The modification of diatomaceous earth mainly includes chemical modification and physical modification, in which the chemical modification is performed by, for example, quaternary ammonium salt, chitosan, or the like.
Nereistoxin insecticides are agricultural insecticides which are biomimetically synthesized according to the chemical structure of nereistoxin, the acting part of the nereistoxin insecticide is cholinergic synapse, and the nereistoxin insecticide can be used for preventing and treating various leaf eating pests and boring pests on various crops such as rice, vegetables, sugarcane, fruit trees, tea trees and the like, and has good prevention and treatment effects on aphids, leafhoppers, plant hoppers, thrips, mites and the like.
Nereistoxin insecticides are basically good in water solubility, so that most of nereistoxin insecticides are prepared into water-based preparations, but have certain defects in application, and the release rate cannot be controlled.
Disclosure of Invention
Aiming at the defects in the prior art and aiming at widening the waste molasses of the sugar industry, the invention discovers that the diatomite modified by the molasses can effectively load nereistoxin insecticides and has excellent controlled release effect. Not only solves the problem of the controlled release of nereistoxin pesticides, but also widens the application field of molasses.
In order to solve the above problems, the present invention adopts the following technical means.
The invention relates to a slow-release pesticide-fertilizer composition which comprises molasses, diatomite, nereistoxin insecticide and optional sugar refinery waste, wherein the weight percentage of each component is,
molasses 5-15%
Diatomite 70-94.5%
Nereistoxin insecticide 0.01-20%
0-10% of sugar mill waste.
Preferably, the weight percentage of each component is,
molasses 5-15%
Diatomite 70-94.5%
Nereid toxin insecticide 0.5-10%
0-10% of sugar mill waste.
Preferably, the weight percentage of each component is,
molasses, 7-11%
Diatomite 83-92%
0.6 to 2 percent of nereistoxin insecticide,
0-5% of sugar mill waste.
More preferably, the weight percentage of each component is,
molasses, 7-9%
Diatomite 87-92%
Nereid toxin insecticide, 0.8-1.2%
2-4% of sugar mill waste.
In the scheme of the invention, the molasses is solid molasses, preferably solid cane molasses or solid beet molasses; advantageously, the solid molasses is pure solid molasses, such as pure solid cane molasses, pure solid beet molasses, preferably pure solid cane molasses. The solid molasses used in the present invention has a water content of less than 1.5 wt.%, a total sugar content of greater than 80 wt.%, and a solids content of greater than 98.5 wt.%.
The solid molasses contains not only sugar, but also protein, amino acid and various mineral ions such as potassium, magnesium, calcium, phosphorus and the like. Wherein, the sugar in the molasses plays a role of a binder on one hand and is used for fixing the pesticide components; on the other hand, the fertilizer can be used as plant nutrient substances to provide essential nutrient elements for crop growth through continuous release. In addition, proteins, amino acids and mineral ions in the molasses are used as a modifier of the diatomite to chemically modify the diatomite so as to increase the loading capacity of the diatomite; on the other hand, the fertilizer can also be used as plant nutrient substances to provide essential nutrient elements for the growth of crops through continuous release.
In the scheme of the invention, the sugar refinery waste is sugar refinery filter mud, or a concentrated, purified and dried product of sugar refinery alcohol waste liquid, such as fulvic acid, potassium fulvate biochemical and the like.
In the scheme of the invention, the specific surface area of the diatomite is 38-45m2Per g, pore volume of 0.60-0.75cm3Per g, pore radius of
Preferably, the specific surface area of the diatomite is 40-45m2Per g, pore volume of 0.65-0.70cm3Per g, pore radius of
The parameter range of the kieselguhr is an ideal range when molasses is used for modification, because molasses solution has certain viscosity and fluidity, if the surface area, pore volume and pore radius are too small, the molasses cannot smoothly and fully enter pores to complete modification; if the pore volume and pore radius are too large, the molasses solution will not be smoothly held in the pores, and there is a risk of self-bleeding, which may reduce the modification effect of diatomaceous earth.
In the scheme of the invention, the nereistoxin insecticide is selected from one or more of dimehypo, monosultap and cartap, and the dimehypo is preferred.

weighing 6kg of pure solid cane molasses, adding 10kg of water to dilute into a solution, and preparing a molasses solution;
weighing 90.2kg of diatomite, heating to 270 ℃, and keeping for 2 hours for thermal activation; then, cooling to 48 ℃, and spraying the prepared molasses solution on the surface of the diatomite while stirring; after spraying, stirring for 30 minutes; then freeze-drying for 12 hours to obtain molasses modified diatomite;
weighing 0.8kg of bisultap, dissolving the bisultap in dimethyl sulfoxide to prepare bisultap solution, and then soaking the prepared molasses modified diatomite in the solution for 7 hours while continuously stirring for full adsorption; and then standing, volatilizing the solvent, drying at 65 ℃ for 3 hours, and mixing with 3kg of sugar mill filter mud to obtain the slow-release pesticide-fertilizer composition.
