Water soluble fertilizer containing chitosan oligosaccharide and amino acid and preparation method thereof

Abstract

The invention discloses water soluble fertilizer containing chitosan oligosaccharide and amino acid. The water soluble fertilizer containing chitosan oligosaccharide and amino acid is characterized by being mainly prepared from the following raw materials in parts by weight: 5-20 parts of chitosan oligosaccharide, 50-250 parts of amino acid, 5-25 parts of zinc salt, 1-10 parts of borax, 30-80 parts of a chelating agent and 30-80 parts of organic silicon. The water soluble fertilizer containing chitosan oligosaccharide and amino acid is prepared by means of mixing, stirring, chelating and the like. The water soluble fertilizer containing chitosan oligosaccharide and amino acid is applicable to grain crops, commercial crops and vegetable crops by means of root irrigation, seed soaking, drop irrigation, sprinkling irrigation and the like. The water soluble fertilizer containing chitosan oligosaccharide and amino acid is non-toxic and harmless, contains no hormone, has no residue and can be used for balancing and regulating growth development of crops, promoting metabolism and photosynthesis of plants and delaying leaf senescence of the crops, and immunocompetence of the crops on various germs can be effectively improved; meanwhile, crop yield and agricultural product quality are improved, and the water soluble fertilizer containing chitosan oligosaccharide and amino acid has a certain drought resisting and cold resisting effect.

Description

technical field

[0001] The invention belongs to the field of agricultural fertilizers, and relates to an amino acid water-soluble fertilizer, in particular to a chitosan-containing amino acid water-soluble fertilizer. Background technique

[0002] With the rapid development of the industrial commodity economy and the increase of market demand, modern people's living standards are rising day by day and the awareness of health care is constantly strengthening, the demand for pollution-free food, vegetables and other crops is increasing, and the technical content of the products is required to be higher. However, excessive use of chemical fertilizers, pesticides, additives and hormones in agriculture will remain in crops, causing great harm to human health. Most of the water-soluble fertilizers currently on the market focus on solving the problems of crop nutritional imbalance and premature aging prevention in the middle and late stages, without considering how to improve the i...
