Problems solved by technology

[0004] At present, in agricultural planting, fertilizers and pesticides are usually applied separately. This is because different crops have different requirements for drugs and fertilizers during the growth period. The effect of the product is affected; and after applying the medicine and fertilizer at the same time, the controlled release and slow release treatment technology of different medicines and fertilizers is also difficult
[0005] Patent authorization announcement number CN102674956B discloses a bactericidal fertilizer granule containing azoxystrobin, which uses fertilizer as a carrier, and azoxystrobin and carrier, filler, corrosion inhibitor and binder are mixed and granulated , to obtain granules with sterilization and fertilizer effects, but the essence of this kind of fertilizer granules is the same as the effect of separate application. It only has a certain slow-release effect, which can properly prolong the incubation period of drug and fertilizer effects. To achieve the controlled release effect on the potency of the fertilizer, the application effect is poor
[0006] The patent authorization announcement number CN104151088B discloses a medicine fertilizer slow-release preparation, its preparation method and application method. In this technical scheme, the insecticide imidacloprid, the fungicide fludioxonil and the compound fertilizer are mixed to prepare medicine fertilizer granules, which have sufficient fertilizer efficiency. , Insecticidal and sterilizing effect is better, but because it is similar to the preparation method of the previous disclosed technical scheme, there are still deficiencies in the controlled release treatment

Abstract

The invention relates to the technical field of pesticide preparations and specifically relates to a sustained-release pesticide fertilizer granula and a production method thereof. The pesticide fertilizer granula is prepared from a sustained-release coating layer and an inner effective matter, wherein the sustained-release coating layer is prepared from talcum powder, neutral bentonite, hydroxymethyl cellulose and chitosan which are mixed according to the mass ratio of 8 to 5 to 2 to 1; the effective matter is prepared from sustained-release medicine, compound fertilizer, a wetting expandingagent and a filling agent; the sustained-release medicine is a coated systematic type pharmaceutical preparation; the systematic type pharmaceutical preparation and a mesoporous AcF micro powder carrier are mixed and then coated; a coating material is prepared from the following ingredients of polyglycolic acid, talcum powder, mesoporous silica, cyclodextrin, liquid paraffin, polyvinyl alcohol, calcium dodecyl benzene sulfonate and deionized water. The pesticide fertilizer granula is treated by a special coating technology, has the characteristics of quick and stable fertilizer efficiency andslow and durable insect killing pesticide effect and is suitable for synchronous pesticide fertilizer application of flowers and nursery stock plants.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to a slow-release medicinal fertilizer granule and a production method thereof. Background technique [0002] Slow-release fertilizer, also known as controlled-release fertilizer, is a coated fertilizer made of a thin layer of hydrophobic material on the surface of the fertilizer granules. Water can enter the porous semi-permeable membrane, and the dissolved nutrients diffuse out of the membrane to continuously supply crops. That is to adjust the release rate of fertilizer nutrients and release nutrients according to the needs of crops to achieve a dynamic balance between the intensity of elemental fertilizer supply and the physiological needs of crops. Coated urea, film-coated urea, long-acting ammonium bicarbonate, CA, and CR fertilizers on the market are one type of slow-release fertilizer. The slow-release fertilizer has the following advantages: 1. The amount of...
