Embodiment 1

[0022] The inventor has carried out field test in Tianjin.

[0023] The test site is the test field in Tianjin Development Zone. The test soil is sandy soil with average fertility. The components of the seed coating agent used in the present invention (both are weight percentages) are:

[0024] Take 77% of γ-polyglutamic acid, 18% of polyvinyl alcohol, 2% of hydroxypropyl methylcellulose and methyl cellulose (mass ratio 5:1), surfactant OP 20 1%, 0.5% gentian violet, 0.2% carbendazim, 0.3% thiram, 1% carbofuran. Prepare the coating agent, take 100g and coat 5 kg of corn seeds, and let it dry naturally.

[0025] The tested corn, its seed quality testing results: purity ≥ 95.0%, clarity ≥ 98.0%, germination rate ≥ 80%, test A is a commercially available seed coating agent (16.8% multi-for-gram suspension seed coating agent, of which more than Bacillus 3.8%, thiram 6%, carbofuran 7%), B is the above seed coating agent, C is the blank control.

[0026] The experiment was rando...

Embodiment 2

[0040] The components of the seed coating agent used in the present invention (all are percentages by weight) are:

[0041] Take 70% of γ-polyglutamic acid, 26% of polyvinyl alcohol, 1.5% of hydroxypropyl methylcellulose and methylcellulose (mass ratio 5:1), surfactant OP 20 0.1%, 0.5% gentian violet, 0.2% carbendazim, 0.8% thiram, 0.9% carbofuran. Prepare the coating agent, take 100g and coat 5 kg of corn seeds, and let it dry naturally. Test corn is with specific implementation example 1. B is the above-mentioned seed coating agent, and C is the blank control. Other conditions are with embodiment 1.

[0042] Seedling emergence rate of each treatment in table 4

[0043]

[0044]

[0045] As can be seen from Table 4, the highest seedling emergence rate is that the B seed coating is 87.9%; the second is the A seed coating is 84.3%, and the third is that the blank control without coating is 83.5%. Moreover, the seedlings of the B seedlings emerged neatly, about 2 days...

Embodiment 3

[0056] The components of the seed coating agent used in the present invention (all are percentages by weight) are:

[0057] Take 65% of γ-polyglutamic acid, 30% of polyvinyl alcohol, 2% of hydroxypropyl methylcellulose and methylcellulose (mass ratio 5:1), surfactant OP 20 1%, 0.5% gentian violet, 0.2% carbendazim, 0.3% thiram, 1% carbofuran. Prepare the coating agent, take 100g and coat 5 kg of corn seeds, and let it dry naturally.

[0058] For testing corn with embodiment 1. B is the above-mentioned seed coating agent, and C is the blank control. Other conditions are with embodiment 1.

[0059] Seedling emergence rate of each treatment in table 7

[0060]

[0061]

[0062] As can be seen from Table 7, the highest seedling emergence rate is 87.6% of the B seed coating; followed by the A seed coating of 85.7%, and the third is the non-coated blank control of 84.9%. Moreover, the seedlings of the B seedlings emerged neatly, about 2 days earlier than the control seedl...

Abstract

The invention discloses a seed coating, which is characterized by being formed by mixing 65-80% of gamma-polyglutamic acid, 15-30% of dispersant, 0.5-2% of bonder, 0.05-1% of surfactant, 0.05-2% of biocide and 0.1-0.5% of vigilant dye by weight percent. According to the seed coating taking polyglutamic acid as a primary component, the seed growth microenvironment can be improved, the germination of seeds and the growth and development of seedlings can be promoted, the quality of rice seedlings can be improved, the pesticide effect of pesticides can be improved, the pesticides diffused in the environment and the contact amount of non targets can be reduced, no residues are generated on the leaf surfaces, the disease prevention and pest control effects of the seed coating are improved, and the requirements of green ecological agriculture development are met.

Description

Technical field: [0001] The invention discloses a seed coating agent, in particular to a seed coating agent suitable for grain crop seeds. Background technique: [0002] Seed coating technology is a new agricultural production technology that has been highly praised by agricultural experts in my country and generally welcomed by farmers in recent years, and has achieved good results in production time. Coating technology is an important means to build high-yield, high-quality, high-efficiency modern agriculture and sustainable agricultural development. Seed coating of commercial seeds is one of the important technical measures to improve the level of science and technology and production. Therefore, finding a kind of seed coating agent that can resist diseases and insect pests and increase production, and is friendly to the environment is the subject of people's research all the time. [0003] Shanghai University of Engineering and Technology has done in-depth research on t...
