High-carbon-based soil remediation fertilizer for promoting growth of root system and method

Abstract

The invention belongs to the technical field of development of agricultural resources and soil improvement, and particularly relates to a high-carbon-based soil remediation fertilizer for promoting growth of a root system and a preparation method of the high-carbon-based soil remediation fertilizer. The high-carbon-based soil remediation fertilizer is prepared by compounding the following raw materials in percentages by mass by a certain process: biomass charcoal 25%-45%, an organic fertilizer 45%-55%, a conditioner 5-10%, mineral substances 10-15%, a microorganism bacterium agent 1-5%, indole butyric acid potassium salt 0.02%-0.1%, and 5-nitroguaiacol sodium salt 0.01%-0.1%. The prepared product is high in content of bioactivators, has effect of in-situ soil remediation, can be widely used for crops such as tobacco, fruit trees, wheat, paddy rice, corn and vegetables, and is the high-carbon-based soil remediation fertilizer for production of organic green agricultural products.

Description

technical field [0001] The invention belongs to the technical field of agricultural resource development and soil improvement, and in particular relates to a high-carbon-based soil repair fertilizer and a method for promoting root growth. Background technique [0002] Soil is the basis for human survival and development. In recent years, the long-term irrational use of a large number of new agricultural chemicals in my country's agricultural production, and the increase of veterinary drug residues in livestock and poultry excreta have caused soil pollution to increase year by year, and the soil carbon pool is out of balance, that is, the soil C / N ratio has changed from the past 22-25 down to 10-12, or even lower, directly affects soil microbial environmental factors, and then affects microbial reproduction and activity, reduces the soil mineralization effect, makes soil fertility obstacle factors more and more serious, and ultimately affects the normal growth and development ...
