Special rapeseed fertilizer and preparation method of special rapeseed fertilizer

Abstract

The invention provides a special fertilizer for rape, which is made of the following raw materials in parts by weight: agricultural straw 40-50, coated urea 20-30, monoammonium phosphate 10-12, coated ammonium sulfate 10-12, coated chlorine Potassium chloride 16-18, plant ash 20-30, manganese sulfate, ferrous sulfate, magnesium sulfate 1-2 each, zinc sulfate 0.1-0.5, boric acid 0.1-0.3, volcanic ash 10-12, charcoal 5-7, neem fruit powder 3-4, basil powder 3-4, bagasse 10-15, quartz sand 10-15, weathered coal 18-22, carboxymethyl cellulose 3-4, 30% sulfuric acid 15-20, lime 5-10, Animal hair 10-15, wintergreen oil 4-6. The hair is acid-decomposed into amino acids to generate amino acid chelated medium and micro-fertilizer liquid, then the quartz sand is sintered to obtain the fertilizer carrier, the organic fertilizer is fermented, and then the nitrogen, phosphorus and potassium fertilizer is mixed with the carrier, organic fertilizer and plant pesticides to produce granules, and finally coated with wintergreen oil. The fertilizer of the invention can significantly improve the utilization rate of fertilizer efficiency, play a slow-release effect, reduce the amount of fertilization, and reduce pesticide residues. The yield and quality of rapeseed are improved, and at the same time, the effects of turning waste into treasure and circular economy are realized.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special fertilizer for rape and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and rape is the main source of edible oil plants in our country. With the continuous increase of the world population, the demand for edible oil is increasing. How to improve the yield and quality of rape is an inevitable requirement of social development. [0003] At the same time, our country is in a stage of rapid development, and the development of industry and agriculture is very fast. With the development of industry and agriculture, a large number of industrial and agricultural wastes are produced. How to solve these industrial and agricultural wastes and realize the circular economy is an urgent need to solve the development problem. [0004] Currently, most of the fertilizers used in rapeseed planting are inorganic fertilizers...

AI Technical Summary

Problems solved by technology

[0004] Currently, most of the fertilizers used in rapeseed planting are inorganic fertilizers. Due to the long-term excessive use of inorganic fertilizers, nutritional imbalances, soil compaction, soil fertility decline, and serious shortage of organic matter lead to a decline in the nutritional quality of rapeseed, low yield, poor stress resistance, and oil quality. series of questions, with
