Problems solved by technology

In recent years, with the rapid growth of population, in order to increase crop yield, people use a large amount of chemical fertilizers and pesticides, coupled with unscientific fertilization methods and unreasonable fertilization habits, etc., which lead to the decrease of organic matter content in the soil, the loss of nutrients, and the acidification of the soil. , compaction, low utilization rate of nitrogen, phosphorus, potassium and other nutrients, imbalance of soil flora, decreased biological activity, increase of harmful bacteria and harmful substances, serious decline in soil fertility, and serious challenges to sustainable agricultural development
The abuse of chemical fertilizers and pesticides has not only increased the burden on farmers, but also caused a large increase in chemical residues and other harmful substances in agricultural products, seriously affecting human health and survival

Abstract

The invention discloses a high-concentration compound microbial fertilizer prepared by tower-type melt granulation and a preparation method thereof, belonging to the technical field of fertilizers. The fertilizer is composed of 300-500 parts of urea, 130-250 parts of monoammonium phosphate, 30-60 parts of humic acid, 200-300 parts of potassium sulfate, 1-10 parts of magnesium sulfate, 10-20 parts of compound microbial inoculant, 10-30 parts of polyaspartic acid, 30-50 parts of zinc sulfate, 20-30 parts of calcium superphosphate, 50-100 parts of oyster powder, 20-40 parts of silanization-modified zeolite, 3-5 parts of polyvinyl alcohol and 5-8 parts of urea formaldehyde. The fertilizer is reasonable in formula, can effectively improve the soil quality, implements balanced nutrient release, satisfies the demands of citruses for different nutrients in different growth periods, and can effectively prevent various physiological diseases from generation.

Description

technical field [0001] The invention relates to a composite microbial bacterial fertilizer, in particular to a tower-type melt granulation high-concentration composite microbial bacterial fertilizer and a preparation method thereof. Background technique [0002] As we all know, China is a large agricultural production country. my country feeds more than 20% of the world's population on less than 10% of the world's arable land. In order to continuously increase the production of agricultural products and food, my country uses more and more chemical fertilizers. In recent years, with the rapid growth of population, in order to increase crop yield, people use a large amount of chemical fertilizers and pesticides, coupled with unscientific fertilization methods and unreasonable fertilization habits, etc., which lead to the decrease of organic matter content in the soil, the loss of nutrients, and the acidification of the soil. , compaction, low utilization rate of nitrogen, phos...
