Problems solved by technology

However, at present, various slow-release / controlled-release fertilizers at home and abroad generally have shortcomings such as the use of a large amount of toxic solvents, poor biodegradability of the coating, and poor impact resistance of the coating. Frequent collisions will easily cause damage to the coating layer, and its nutrient release rate will undergo unforeseen degradation, which greatly affects the application prospects of slow-release / cavity-release fertilizers

Abstract

The invention discloses an anti-impact chitosan film coating slow release fertilizer for flat peaches and a preparation method thereof, and relates to the technical field of a fertilizer. The anti-impact chitosan film coating slow release fertilizer is prepared from a core fertilizer and an anti-impact chitosan film coating layer coating the core fertilizer, wherein the anti-impact chitosan film coating layer accounts for 3 to 7 percent of the weight of the core fertilizer; the core fertilizer is prepared from the following raw materials including ammonium chloride, ammonium bicarbonate, ammonium sulfate, monoammonium phosphate, monocalcium phosphate, calcium sulfate, ammonium polyphosphate, potassium sulphate, sodium borate, ammonium humate, trace elements, actinomycetes and bacillus subtilis; the anti-impact chitosan film coating layer is prepared from the following raw materials including chitosan, phthalic anhydride, carbon nanometer tubes, bentonite, carboxymethyl cellulose sodium, polyvinyl alcohol, propanediol, glutaraldehyde and ammonium chloride. Various nutrition ingredients are reasonably proportioned in the core fertilizer; carbon nanometer tubes are introduced into thefilm coating layer material; the prepared slow release fertilizer can provide nutrients for the flat peaches in a balanced and efficient way; the health growth of the flat peaches can be promoted; the yield of the flat peaches is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an impact-resistant chitosan-coated slow-release fertilizer for flat peaches and a preparation method thereof. Background technique [0002] Pan peach is rich in nutrition and balanced, containing protein, fat, sugar, calcium, phosphorus, iron and vitamin B, C and other ingredients, it is a fruit with high nutritional value. The flat peach fruit has a unique shape, delicate flesh, sweet and delicious taste. After eating, it can invigorate the heart and blood circulation, clear away heat and beautify the skin, moisten the intestines and laxatives, help digestion, and prevent many diseases. It is very popular among consumers. [0003] Fertilization is an important factor affecting yield and quality in flat peach cultivation except for variety and water. At present, there is an unreasonable situation in the ratio of each component in common fertilizers for flat peaches, and the...
