Preparation method of biological nanometer fertilizer

Abstract

A preparation method of a biological nanometer fertilizer comprises the following steps: preparing a nanometer adsorption carrier from the raw materials comprising coal ash, hydroxyapatite, vermiculite, sepiolite, an all-silicon molecular sieve, magnesium aluminum hydrotalcite, kaolin, hydroxypropyl methyl cellulose and deionized water ; preparing the biological nanometer fertilizer from the raw materials comprising the nanometer adsorption carrier, bacillus subtilis, bacillus mucilaginosus, bacillus megaterium, urea, ammonium hydrogen carbonate, potassium sulfate, citric acid, borax, crop straws and glucose. According to the preparation method of the biological nanometer fertilizer, the yield of crops can be increased, the microbial environment of soil can be improved and the soil structure is recovered; application of pesticide can be reduced and the quality of the crops is improved ; the preparation method of the biological nanometer fertilizer is suitable for grain, cotton and linen, legume crops, oil crops, vegetables, melons, fruit and the like.

Description

technical field [0001] The invention relates to the field of preparation of agricultural cultivation fertilizers, in particular to a preparation method of bionano fertilizers. Background technique [0002] Agriculture is the basic industry of the national economy. The output of agriculture has a profound impact on the security of the national economy. With the continuous development of agricultural technology, agricultural production is increasingly dependent on chemical fertilizers. At present, the amount of chemical fertilizers used in my country ranks first in the world, and it shows a trend of increasing year by year. [0003] However, traditional fertilizers are still mainly inorganic fertilizers containing nitrogen, phosphorus, and potassium. With the transfer of rural labor force and the transformation of planting patterns, the amount of farm soil and fertilizers entering the field has decreased year by year. The amount of bacteria dropped sharply, the soil compacti...

Problems solved by technology

[0003] However, traditional fertilizers are still mainly inorganic fertilizers containing nitrogen, phosphorus, and potassium. With the transfer of rural labor force and the transformation of planting patterns, the amount of farm soil and fertilizers entering the field has decreased year by year. Bacterial count dropped sharply, soil compaction was serious, crop diseases and insect pests occurred frequently, yield per mu was stagnant

[0004] Bio-organic fertilizers have good environmental benefits, but due to the constraints of production technology and other aspects, the bio-organic fertilizers currently on sale in my country have incomplete fermentation, high content of bacteria, low content of probiotics, single species of probiotics and their effects, The short survival period of the strains and other problems make the effect of bio-organic fertilizers not obvious, which affects the rapid promotion and application of bio-organic fertilizers
