Problems solved by technology
Compared with ordinary fertilizers, these fertilizers have a certain slow and controlled release effect, but because the coating material is water-soluble, its nutrient release rate is greatly affected by water. The adaptability of crops is poor, and the law of fertilizer nutrient release is difficult to match the law of crop nutrient absorption

Abstract
The invention discloses a high-purity chito-oligosaccharide controlled release fertilizer and relates to the technical field of agricultural fertilizers. The high-purity chito-oligosaccharide controlled release fertilize is made from 4% of chito-oligosaccharide coated urea, 6% of another chito-oligosaccharide coated urea, urea, ammonium sulfate, calcium superphosphate, calcium magnesium phosphate, potassium sulfate, humic acid, and EDTA (ethylene diamine tetraacetic acid) chelated trace elements. The high-purity chito-oligosaccharide controlled release fertilizer has unique action on growth of crops, has the effects such as activating crop cells and promoting growth, can activate defensive reaction in plants, start anti-virus genetic expression and induce disease resistance in the crops, has the function of immunizing and killing various fungi, germs and viruses to decrease disease and pest damage to the crops, also can effectively increase the quantity and activity of soil microorganisms and improve the soil environment, is a multifunction novel fertilizer green, pollution free and soil improving, and is worthy of wide application.
Description
technical field [0001] The invention belongs to the technical field of slow and controlled release fertilizer production, in particular to a high-purity chitosan oligosaccharide slow release fertilizer based on separation technology and a preparation method thereof. Background technique [0002] Chitosan oligosaccharide refers to oligosaccharides linked by D-glucosamine with β-1.4 glycosidic bonds, which are obtained by degrading chitin oligosaccharides and then degraded, or low-toxicity and sterilization extracted by microbial fermentation It is a low molecular weight product with good water solubility, great function and high biological activity. Oligochitosan can be used in the agricultural field. Oligochitosan itself is rich in C and N, which can be decomposed and utilized by microorganisms as nutrients for plant growth. Oligochitosan can also induce disease resistance of plants and can be developed as a biological pesticide, Growth regulators and fertilizers, etc....
