Embodiment 2

[0028] A slow-release medicinal fertilizer for rice containing imidacloprid and pyrazosulfuron-methyl, which comprises the following raw materials in mass fractions: 1.2% imidacloprid, 0.1% tetrachlorantraniliprole, 3% fenthiazamide, and 0.4% pyrazosulfuron-methyl , NPK compound fertilizer 50%, medical stone powder 10%, modified sawdust 15%, ethyl cellulose 5%, tapioca starch 5%, acetate starch 5%, dispersant 0.2%, emulsifier 0.3% and water 3%.

Embodiment 3

[0030] A preparation method for slow-release medicinal fertilizer for rice containing imidacloprid and pyrazosulfuron-methyl, comprising the following steps:

[0031] 1) Use the laccase / TEMPO system to oxidize the primary hydroxyl groups on the sawdust into aldehyde groups to obtain oxidized sawdust, and then graft aspartic acid onto the oxidized sawdust through the Schiff base reaction, the mass ratio of aspartic acid to oxidized sawdust 1:10, drying to obtain modified sawdust;

[0032] 2) Dissolve 40 kg of nitrogen, phosphorus and potassium compound fertilizer in 100 kg of water, stir evenly, filter out insoluble particulate matter, and obtain a fertilizer solution; 0.3 kg of imidacloprid, 0.02 kg of tetrachlorantraniliprole, 0.5 kg of benzothiazamide, pyridoxine Add 0.1 kg of rimsulfuron-methyl, 0.05 kg of dispersant, 0.05 kg of emulsifier and 70 kg of fertilizer solution into the sander, and then shear and sand the material until the particle size is less than 5 μm to obta...

Abstract

The invention provides a slow-release pesticide fertilizer containing imidacloprid and pyrazosulfuron-ethyl for rice. The slow-release pesticide fertilizer comprises the following raw materials in parts by mass: 0.6 to 1.2% of imidacloprid, 0.05 to 0.1% of tetrachlorantraniliprole, 1%-3% of mefenacet; 0.2 to 0.4% of pyrazosulfuron-ethyl, 40%-50% of a nitrogen-phosphorus-potassium compound fertilizer, 10%-15% of medical stone powder, 15%-20% of modified sawdust, 5%-10% of ethyl cellulose, 5%-10% of cassava starch, 5%-10% of acetate starch, 0.1%-0.2% of a dispersing agent, 0.1%-0.3% of an emulsifying agent and 1%-3% of water. The invention also provides a preparation method of the pesticide fertilizer. The pesticide fertilizer has the characteristics of insect killing, weeding and nutrient supply for rice, and also has the function of releasing nutrients in stages and the like.

Description

technical field [0001] The invention relates to the field of pesticides and fertilizers. More specifically, the invention relates to a slow-release medicinal fertilizer for rice containing imidacloprid and pyrazosulfuron-methyl and a preparation method thereof. Background technique [0002] Rice is an important food crop in my country. With the increase of population, the demand for rice is also increasing. The cultivation of rice requires repeated fertilization, weeding, and insecticide, which is labor-intensive and has high production costs. With the improvement of science and technology, agricultural production will develop in the direction of intensification, scale and high efficiency. In recent years, pesticides such as herbicides and insecticides have been mixed with fertilizers to make fertilizers with slow-release functions. While fertilizing, they also play the role of weeding and insecticide. One field operation can receive multiple effects and improve labor eff...
