Abstract

The invention discloses a degradable mulberry seed coating film agent which comprises the following raw materials in parts by mass: 24-30 parts of humic acid, 0.3-0.5 part of chitosan, 1-5 parts of urea, 4-8 parts of an environment-friendly film-forming agent, 4-8 parts of an environment-friendly plasticizer, 0.3-0.5 part of a water-retaining agent, 1-3 parts of a bactericide, 0.5-1 part of an insecticide, 0.5-1 part of trace elements, 110-245 parts of deionized water and strong base corresponding to the amount of acid radical substance in the humic acid, the invention also discloses a preparation method and a use method of the degradable mulberry seed coating film agent, and the degradable mulberry seed coating film agent can improve the soil structure, improve the physical and chemical properties of soil, improve the water retention and fertilizer retention capacities, stimulate the growth and development of crop roots, enhance the adverse environment resistance of crops, and improve the quality of the crops. According to the invention, materials with a degradable function are fully utilized as raw materials, so that the fertilizer is non-toxic, harmless, green and environment-friendly, and is simple and convenient to use and operate.

Description

technical field [0001] The invention belongs to the technical field of seed coating film, and in particular relates to a degradable mulberry seed coating film and a preparation method and application method thereof. Background technique [0002] Pesticides are very important to agriculture, but because pesticides are usually applied by spraying, organic solvents and some pesticides in pesticides float in the air and pollute the atmosphere; farmland is washed by rain, and pesticides enter rivers and pollute the ocean. In this way, pesticides are carried to all parts of the world by air currents and water currents, and pesticides in residual soil can reach deep into the formation through osmosis, thereby polluting groundwater. [0003] With the development of science and technology, seed coating technology has emerged as the times require, and has become a plant protection technology widely used in my country. Seed coating technology is to wrap the seed coating agent with ins...
