Description
Technical field
The present invention relates to pesticide field, and in particular to a kind of AVM slow releasing composition.
Background technology
Molasses are the byproducts of sugar industry, sticky, dark brown and in semifluid object.Have in molasses containing substantial amounts of
Beneficial material, such as carbohydrate, amino acid and protein, in addition in molasses also contain substantial amounts of mineral matter, such as potassium, sodium, magnesium, calcium,
Phosphorus etc..Molasses can be divided into liquid molasses and solid molasses according to its form, and wherein solid molasses include pure solid molasses and logical
The solid molasses containing other carriers crossed carrier adsorption and be prepared into.Molasses as one of Main By product of sugar industry,
It is current to be mainly used for by processing as animal feed, as fermentation raw material of alcohol industry etc., and purposes is more single.
Diatomite is a kind of using diatom as a kind of biogenic deposit rock lived, and chemical composition is with SiO2Based on, it is distributed
Extensively, it is distributed in states such as China, Denmark, the U.S., Japan, France.China's diatomite rich reserves, are distributed in Yunnan, four
Multiple provinces such as river, Shandong.Diatomite is a kind of preferable absorption carrier, but the diatomite nature difference of each place is larger.
Diatomaceous modification mainly includes chemical modification and physical modification, and wherein chemical modification is entered such as by quaternary ammonium salt, chitosan
Row is modified.
AVM is a kind of macrolide insecticide, and excellent prevention effect is respectively provided with to various crop insect.Mesh
Before, for the control release problem of AVM, more universal solution is to be prepared into microcapsule formulations, but a side
Face microcapsule preparation process is complicated, and process technology requires higher, is on the other hand prepared into after microcapsules, cost will increase greatly
Plus.
The content of the invention
The present invention has found can have through the modified diatomite of molasses from the purpose for the waste material molasses for widening sugar industry
Effect load AVM, and with excellent control release effect.This not only solves the control release problem of AVM, together
When also widened the application fields of molasses.
In order to solve the above problems, the present invention uses following technical scheme.
One aspect of the present invention is related to a kind of AVM slow releasing composition, and it is comprising molasses, diatomite, AVM and appoints
Sugar refinery discarded object of choosing, the weight percentage of each component is,
Molasses, 4-12%
Diatomite, 72-96%
AVM, 0.01-20%
Sugar refinery discarded object, 0-8%.
Preferably, the weight percentage of each component is,
Molasses, 4-12%
Diatomite, 72-96%
AVM, 0.1-10%
Sugar refinery discarded object, 0-8%.
It is highly preferred that the weight percentage of each component is,
Molasses, 6-9%
Diatomite, 86-94%
AVM, 0.5-1%
Sugar refinery discarded object, 0-4%.
In scheme of the present invention, wherein, described molasses are solid molasses, preferably solid cane molasses or solid
Beet molasses；Advantageously, described solid molasses are pure solid molasses, such as pure solid cane molasses, pure solid sweet tea
Dish molasses, preferably pure solid cane molasses.The water content of solid molasses used in the present invention is less than 1.5wt.%, and total sugar is more than
80wt.%, solid content is more than 98.5wt.%.
Not only contain sugar in solid molasses, but also comprising protein, amino acid and multi mineral ion, such as potassium,
Magnesium, calcium, phosphorus etc..Wherein, on the one hand the sugar in molasses plays binding agent effect, to fixed insecticide ingredient；On the other hand,
As plant nutrient substance essential nutrient element can be provided by being constantly released to plant growth.In addition, the albumen in molasses
Matter, amino acid and mineral ion, on the one hand as diatomaceous modifying agent, chemical modification is carried out to diatomite, is increased it and is born
Loading capability；On the other hand, required nutrition member can also be provided by being constantly released to plant growth as plant nutrient substance
Element.
In scheme of the present invention, wherein, described sugar refinery discarded object is filter mud of sugar refinery, or alcohol waste liquid for sugar refinery
Concentration purification drying object, such as fulvic acid, biochemical fulvic acid potassium.
In scheme of the present invention, wherein, described diatomaceous specific surface area is 38-45m2/ g, pore volume is
0.60-0.75cm3/ g, pore radius isPreferably, described diatomaceous specific surface area is 40-45m2/ g, hole
Volume is 0.65-0.70cm3/ g, pore radius isDiatomite above-mentioned parameter scope, is modified using molasses
When ideal scope because molasses solubles have certain viscosity and mobility concurrently, if surface area, pore volume and pore radius
It is too small, molasses will be unable to smoothly well into hole with completes modification；If pore volume and pore radius are excessive, molasses solubles
It will not be successfully maintained in hole, there is the risk oozed out automatically, this can reduce diatomaceous modified effect.
In another embodiment of the invention, composition of the present invention can be agriculturally acceptable by adding
