Abstract

The invention discloses a macromolecular quick-dissolving fertilizer for vegetables and a preparation method thereof, and belongs to the technical field of chemical fertilizers. The macromolecular quick-dissolving fertilizer is prepared from the following raw materials of urea, potassium dihydrogen phosphate, potassium sulfate, boron sulfate, magnesium sulfate, calcium sulfate, humate, water-soluble chitosan, a synergizer, an anti-caking agent and a promoter, wherein the synergizer is prepared by mixing polyaspartic acid, pullulan polysaccharide and potassium fulvic acid according to a ratio of 1:(2 to 4):(4 to 6); the anti-caking agent is prepared by mixing pullulan-polyglutamic acid crosslinking polymer and methyl naphthalene sulfonic acid sodium salt according to a weight ratio of 1:1;the promoter is prepared from polyacrylamide, fatty alcohol polyoxyethylene ether sodium sulfate, and imide disuccinate tetrasodium according to a weight ratio of 0.8:1:1. The macromolecular quick-dissolving fertilizer has the advantages that the formula is reasonable, and the preparation method is simple; while the output and quality of the vegetables are obviously improved, the soil structure can be adjusted, and the loss of nutritional matters is reduced.

Description

technical field

[0001] The invention belongs to the field of chemical fertilizers, and in particular relates to a special polymer instant fertilizer for vegetables and a preparation method thereof. Background technique

[0002] Vegetables are one of the essential foods in people's daily diet. Vegetables can provide nutrients such as various vitamins and minerals necessary for the human body. According to the statistics of the International Food and Agriculture Organization in 1990, 90% of the VC and 60% of the VA necessary for the human body come from vegetables. In addition, there are a variety of phytochemicals in vegetables, which are recognized as effective components for health. Currently, nutrients in fruits and vegetables that can effectively prevent chronic and degenerative diseases are being discovered by people. The nutrients of vegetables mainly include protein, minerals, vitamins, etc. The higher the content of these substances, the higher the nutritional value...
