Embodiment 1

[0042] The wheat seed coating agent is made of the following raw materials: 32 parts of fludioxonil (10%), 32 parts of metalaxyl powder (35%), 5 parts of boric acid, 5 parts of borax, 10 parts of magnesium sulfate, and 1.8 parts of paclobutrazol , 0.2 parts of algin oligosaccharide, 4 parts of polyvinyl alcohol, 5 parts of sodium carboxymethylcellulose (CMC), 4 parts of rhodamine, compound type of styrene-based phenol polyoxyethylene ether and calcium dodecylbenzenesulfonate 1 part emulsifier.

[0043] The method for preparing wheat seed coating agent, comprises the steps:

[0044] 1) Mix fludioxonil and metalaxyl powder, and ball mill to obtain component A;

[0045] 2) Mix other raw materials, add them to the ball mill of component A, and continue ball milling to obtain mixed raw materials with a fineness of 400-500 mesh, which is component B;

[0046] 3) Put component B into a jet mill for ultrafine pulverization for 15-30 minutes until it reaches 1000 mesh.

Embodiment 2

[0052] The wheat seed coating agent is made of the following raw materials: 30 parts of fludioxonil (10%), 34 parts of metalaxyl powder (35%), 5 parts of boric acid, 5 parts of borax, 10 parts of magnesium sulfate, and 1.8 parts of paclobutrazol , 0.2 parts of algin oligosaccharide, 4 parts of polyvinyl alcohol, 5 parts of sodium carboxymethyl cellulose (CMC), 4 parts of rhodamine, compound type of styrylphenol polyoxyethylene ether and calcium dodecylbenzenesulfonate 1 part emulsifier.

[0053] The preparation method is the same as in Example 1.

[0054] Mix well with wheat seeds at a ratio of 1:800.

[0055] The test showed that: compared with the control without seed dressing, the germination rate of wheat increased by 18.33%, and compared with the control of domestic and imported seed coating agents, the germination rate increased by 7.82% and 2.63% respectively; The number and 1,000-grain weight were also higher than those of the non-dressing control, domestic and impor...

Embodiment 3

[0057] Wheat seed coating agent, made from the following raw materials: 28 parts of fludioxonil (10%), 36 parts of metalaxyl powder (35%), 5 parts of boric acid, 5 parts of borax, 10 parts of magnesium sulfate, 1.8 parts of paclobutrazol , 0.2 parts of algin oligosaccharide, 4 parts of polyvinyl alcohol, 5 parts of sodium carboxymethyl cellulose (CMC), 4 parts of rhodamine, compound type of styrylphenol polyoxyethylene ether and calcium dodecylbenzenesulfonate 1 part emulsifier.

[0058] Preparation method is with embodiment 1.

[0059] Mix well with wheat seeds at a ratio of 1:800.

[0060] Under the application condition of this kind of coating agent, compared with the control without seed dressing, the germination rate of wheat increased by 16.37%, the ear grain weight increased by 16.9%, the disease index of take-all disease decreased by 27.75%, and the disease control effect reached 64.34%. Under the test of this seed coating agent, the average yield of wheat per mu was...

Abstract

The invention provides an efficient drought resisting nutritional type wheat seed coating agent and preparation and application thereof. The efficient drought resisting nutritional type wheat seed coating agent is prepared from the following raw materials in parts by mass of 60-70 of bactericide, 20 of a trace element fertilizer, 1-3 of a drought resistance agent and a growth regulator, 2 of a dispersing agent, 1-3 of an emulsifying agent, 4-6 of a film forming agent and 3-4 of a color warning agent, wherein the bactericide consists of fludioxonil and metalaxyl-M powder; and the trace elementfertilizer consists of boric acid, borax and magnesium sulphate in mass ratio of 1 to 1 to 2. A ball milling technology and a superfine crushing technology are combined, so that a powder seed coatingagent of 1000 meshes is prepared, the seed mixing amount is high, and is as high as 1 to 800, and the powder seed coating agent is convenient to preserve and transport. According to the efficient drought resisting nutritional type wheat seed coating agent, the problems that seeds are small, the consumption of the seeds is high, and the consumption of medicament is high, are solved. The trace element namely boron can increase the maturing rate of wheat. The paclobutrazol can promote vitality of the seeds, and can promote growth of roots, so that the electrical conductivity of the seeds is reduced, the capacity of the roots for absorbing nutrients and lodging resistance and the inverse resistance can be improved, and algin oligosaccharide can improve the drought resistance of the wheat.

Description

technical field [0001] The invention belongs to the field of seed coating, and in particular relates to a high-efficiency drought-resistant nutritional wheat seed coating agent and its preparation and application. Background technique [0002] Wheat is a gramineous plant widely planted all over the world. It is one of the earliest cultivated crops in the world and is the main food crop in my country. To improve lodging resistance, improve seed vigor, and increase seed setting rate, seeds need to be coated. [0003] Wheat seed coating is a pesticide formulation with film-forming properties for wheat seed treatment. The usual wheat seed coating agent is made of pesticide raw materials (insecticides, fungicides, hormones and seed fertilizers, etc.), film-forming agents, wetting agents, dispersants, penetrating agents and other auxiliaries, which can be directly Or coated on the seed surface after dilution to form a water-based suspension preparation with a certain strength and...
