Problems solved by technology

In order to improve the germination rate and resistance of seeds, planting suppliers usually coat cottonseeds with various coating agents. The main substances in the coating agents are insecticides and fungicides, which can reduce the impact of pests and pathogens. Damage to seedlings, but it cannot improve the resistance of seeds, cannot provide the nutrients needed for seedlings to grow, and cannot improve the ability of seeds to resist salt and alkali

Abstract

The invention relates to the technical field of seed coating, in particular to a coated seed capable of improving resistance of cotton and a coating method of the coated seed. The coated seed separately comprises a dry seed, an impermeable layer, a first coating layer, a second coating layer and a third coating layer from inside to outside, wherein the impermeable layer comprises the following components: polyacrylic resin, water, calcined kaolin, palm wax and hydrogenated rosin; the first coating layer comprises the following components: chitin, a dispersing agent, potassium sulphate, potassium dihydrogen phosphate, ammonium molybdate, a plant growth regulator, ferrous sulfate and water; the second coating layer comprises the following components: polyglutamic acid, hydroxymethyl cellulose, a fungicide, carbosulfan, imidacloprid and water; and the third coating agent comprises the following components: polyaspartic acid, gulconic acid mother liquor, a cross-linking agent, chitosan andpeanut hull powder. By the coated seed, the germination rate and the variety resistance of a cotton seed can be improved, sufficient nutrition can be provided for growth of a seedling, and the tolerance of a cotton seedling to saline-alkali soil is improved.

Description

technical field [0001] The invention relates to the technical field of seed coating, in particular to a coated seed for improving cotton resistance and a coating method thereof. Background technique [0002] Cotton is an important crop and the most important source of natural plant fiber in the textile industry. Cotton cloth woven from cotton fiber has the advantages of easy warmth, soft and close-fitting, good skin-friendly, hygroscopicity, and good air permeability. Cotton is an important strategic material. my country's cotton production has long occupied the first place in the world, and its cotton consumption is also among the top in the world. Xinjiang, Shandong, Hebei, and Hubei are several important cotton-producing regions in my country. [0003] Cotton crops do not have high requirements on the soil. Therefore, the main production areas of cotton in my country are the northwest regions with relatively harsh natural conditions. The hydrological conditions, soil pH a...
