Abstract

The invention provides a special rapeseed fertilizer consisting of the following raw materials in parts by weight: 40-50 parts of agricultural straws, 20-30 parts of enveloped sulfur urea, 10-12 parts of monoammonium phosphate, 10-12 parts of enveloped ammonium sulfate, 16-18 parts of enveloped potassium chloride, 20-30 parts of plant ashes, 1-2 parts of manganese sulfate, 1-2 parts of ferrous sulfate, 1-2 parts of magnesium sulfate, 0.1-0.5 part of zinc sulfate, 0.1-0.3 part of boric acid, 10-12 parts of cinerite, 5-7 parts of wood charcoals, 3-4 parts of neem fruit powders, 3-4 parts of radix stemonae powders, 10-15 parts of bagasse, 10-15 parts of quartz sands, 18-22 parts of decomposed coals, 3-4 parts of carboxymethylcellulose, 15-20 parts of 30% of sulfuric acid, 5-10 parts of limes, 10-15 parts of animal hairs and 4-6 parts of wintergreen oil. The special rapeseed fertilizer is prepared by a method comprising the following steps: conducting acidolysis on hairs to generate amino acid, then generating a micro element fertilizer liquid and an intermediate element fertilizer liquid chelated with amino acid, then sintering the quartz sands to prepare a fertilizer carrier, fermenting an organic fertilizer, mixing a nitrogen-phosphorus-potassium fertilizer, the carrier, the organic fertilizer and a vegetable insecticide, then granulating, and finally adopting the wintergreen oil for enveloping. According to the special rapeseed fertilizer provided by the invention, the fertilizer utilization ratio is improved obviously, the slow release effect is achieved, the fertilizer application amount is lowered, the pesticide residual is lowered, the output and the quality of winter wheat are improved, and the effects of turning waste into wealth and recycling 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...
