Problems solved by technology

However, due to the special structure of some plant growth regulators, they are susceptible to changes in the external environment and have poor stability (such as gibberellins), while some plant growth regulators are susceptible to changes in the external environment due to special odors (such as compound nitrophenols). Sodium) or appearance problems, which affect processing and use, so it is necessary to coat plant growth regulators

Abstract

The invention discloses a preparation method of a film-coated plant growth regulator added to a powder water-soluble fertilizer. The water-soluble polymer material is used as a film-forming agent to coat the surface of the plant growth regulator. The film-forming agent is starch phosphate One or more of sodium, chitosan, xanthan gum, phosphorylated distarch phosphate and sodium alginate are mixed. The film-covered plant growth regulator of the invention has good film-forming performance, can reduce or remove the peculiar smell of some plant growth regulators, and does not need to consider the influence of inorganic salts, acidic substances or alkaline substances on the film-covered plant growth regulator.

Description

technical field [0001] The invention relates to a preparation method of a film-covered plant growth regulator added to a powder water-soluble fertilizer, which is applied in the field of agriculture and forestry. Specifically, the water-soluble polymer material is used as a film-forming agent, and the plant growth regulator is wrapped and added to the powdered water-soluble fertilizer. Background technique [0002] As a class of pesticides used to regulate plant growth and development, plant growth regulators can affect and effectively regulate the growth and development of plants, including cell growth, division, rooting, germination, flowering, fruiting, maturity and A series of plant life processes such as shedding. Used in agricultural production, it can effectively regulate the growth process of crops, achieve stable and increased production, improve quality, and enhance crop resistance. However, due to the special structure of some plant growth regulators, they are s...
