Abstract

The invention relates to liquid slow release compound fertilizer and a preparation method thereof. The fertilizer includes the following raw material components: water absorbing resin, a straw fermentation broth, an inorganic fertilizer solution, and a silicon solution; the water absorbing resin is prepared by reacting acrylic acid, 2-acrylamide-2-methyl propanesulfonic acid, methoxy polyethyleneglycol 550 monomethacrylate, a Sr-10 emulsifier, methyl methacrylate, acrylamide, vinyl acetate, ammonium persulfate with fertilizer water; the straw fermentation broth is prepared by reacting straw,trichoderma spp, fertilizer water, an amino acid liquid, peptone, livestock and poultry feces and waste, and kitchen waste; the inorganic fertilizer solution is prepared by reacting urea, the amino acid liquid, potassium dihydrogen phosphate, the fertilizer water, boric acid with zinc sulfate; and the silicon solution is prepared by reacting silicon mud, the fertilizer water with the amino acid liquid. The fertilizer has excellent slow release performance.

Description

technical field [0001] The invention relates to a liquid slow-release compound fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] With the rapid development of social economy, people are gradually paying attention to the details of the agricultural production process such as the taste and quality of agricultural products, the application of environmentally friendly green organic fertilizers, and the problems of soil pollution caused by pesticides and chemical fertilizers. Due to the advantages of quick results and convenient application of chemical fertilizers, my country is highly dependent on chemical fertilizers. However, excessive application of chemical fertilizers leads to a series of consequences, such as: serious soil pollution, poor taste of crops, decline in crop quality, reduction in crop yield per mu, Defects such as large amount of chemical residues. In recent years, with the strengthening ...
