Problems solved by technology

The coating rate of rapeseed in my country is very low, less than 5%, and there is no special seed coating agent for rapeseed cultivation and production characteristics
[0004] Cultivating strong seedlings is the basis for high and stable yields of rapeseed. Due to the limitation of the seedbed area in production, the seedlings are kept too dense, or the transplanting is too late due to the late harvest of late rice. Seedling

Embodiment 1

[0044] Taking the seed coating agent for processing 100 liters of liquid materials as an example, first dissolve 300 grams of chitosan with 45 liters of 1% glacial acetic acid solution, then dissolve 750 grams of polyvinyl alcohol with 25 liters of water, and then dissolve the dissolved polyvinyl alcohol. Vinyl alcohol solution and weighed liquid materials: 0.3 liters of polyethylene glycol octylphenyl ether, 5 liters of ethylene glycol, 5 liters of acetone, 0.2 liters of phenol, and 0.2 liters of tributyl phosphate were put into the reaction kettle, and then Various weighed powder materials: imidacloprid 500g, carbendazim 5000g, uniconazole 15g, boron fertilizer 300g, manganese fertilizer 100g, zinc fertilizer 100g, gum arabic 5000g, red pigment 1000g Put 1 gram in the kettle, stir while adding, and finally add 19.3 liters of water to make up the used liquid material to 100%, and stir evenly to obtain a red liquid rapeseed coating agent.

Embodiment 2

[0046] Taking the seed coating agent for processing 100 liters of liquid materials as an example, first dissolve 400 grams of chitosan with 45 liters of 1% glacial acetic acid solution, then dissolve 650 grams of polyvinyl alcohol with 25 liters of water, and then dissolve the dissolved polyvinyl alcohol Solution and weighed liquid materials: 0.5 liters of polyethylene glycol octyl phenyl ether, 4 liters of ethylene glycol, 3 liters of acetone, 0.2 liters of phenol, 0.5 liters of tributyl phosphate, and 0.2 liters of phoxim into the reaction In the kettle, put various weighed powder materials: 400 grams of imidacloprid, 6000 grams of carbendazim, 50 grams of uniconazole, 400 grams of boron fertilizer, 150 grams of manganese fertilizer, 150 grams of zinc fertilizer, 4000 grams of gum arabic 1000 grams of pigments are dropped into the still, stir while adding, add 21.6 liters of water at last and make up used liquid material to 100%, stir to obtain liquid rapeseed coating agent. ...

Embodiment 3

[0048] Taking the seed coating agent for processing 100 liters of liquid materials as an example, first dissolve 200 grams of chitosan with 45 liters of 1% glacial acetic acid solution, then dissolve 1000 grams of polyvinyl alcohol with 25 liters of water, and then dissolve the dissolved polyvinyl alcohol Solution and weighed liquid materials: 0.5 liters of polyethylene glycol octylphenyl ether, 6 liters of ethylene glycol, 4 liters of acetone, 0.3 liters of phenol, 0.5 liters of tributyl phosphate, 0.2 liters of phoxim, cyanide Put 0.1 liter of penthrin into the reaction kettle, and then put various weighed powder materials: 350 grams of imidacloprid, 8000 grams of carbendazim, 120 grams of uniconazole, 600 grams of boron fertilizer, 150 grams of manganese fertilizer, zinc fertilizer 150 grams, 4,000 grams of gum arabic, and 1,000 grams of pigment are put into the kettle, stir while adding, and finally add 18.4 liters of water to make up the used liquid materials to 100%, and ...

Abstract

A coating agent for rape seed is prepared from assistant, chemical and water through proportionally mixing and stirring. Said assistant includes filming agent, surfactant, anti-freezing agent, penetrant, etc. Said chemical includes insecticide, bactericide, plant growth regulator, trace element, fertilizer, etc. Its advantage is high effect to prevent and eliminate diseases and pests and increaseyield.

Description

technical field [0001] The invention relates to seed treatment application technology, in particular to a seed coating agent for rape seeds. Background technique [0002] Seed coating agents are substances used to coat plant seeds to make them standardized and commercialized and have film-forming properties. It consists of two parts: one part is the supporting auxiliary agent mainly film-forming agent, including film-forming agent, suspending agent, antifreeze agent, preservative, colloid protective agent, penetrating agent, viscosity stabilizer, diffusing agent and warning color dye etc., its role is to form a colloidal dispersion system with water as the carrier, and the seeds have good film-forming properties, stability, slow-release and warning color after coating; the second is to add micro-organisms according to the crop nutritional formula and insect and disease prevention needs. Fertilizers, plant growth regulators, biological agents, insec...
