Problems solved by technology

However, the main organic matter (humic acid, cellulose, etc.) in organic fertilizers that can adsorb heavy metals can be oxidized and decomposed by microorganisms in the soil. As long as the product is CO 2 , so that the heavy metals adsorbed are slowly released from sinks to sources, causing secondary pollution of the soil
Therefore, the existing technology does not have the characteristics of continuously improving the soil environment and improving the utilization rate of fertilizers

Abstract

The invention provides a biomass charcoal-containing fertilizer assistant, being prepared from 0.5wt percent to 10wt percent of crop growth active factor, 0.5wt percent to 3wt percent of high molecular material and the balance of biomass charcoal. By adding the components and adjusting contents thereof, a fertilizer utilization rate can be increased, the crop yield can be improved, soil volume-weight can be lowered, air permeability and water permeability are enhanced, the forming of soil aggregate is promoted, soil cation exchange capacity is improved, and then soil moisture and fertilizer retention capacity is enhanced; heavy metals, residual pesticide and antibiotics fixed in soil can be adsorbed and can be absorbed less by crops, and crop quality is promoted; in conclusion, the fertilizer assistant has the characteristics of improving soil environment and increasing the fertilizer utilization rate.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer additive containing biochar and its application. Background technique [0002] Research data show that 1 / 5 of the cultivated land in my country is polluted by heavy metals, among which cadmium-contaminated cultivated land involves 25 regions in 11 provinces; especially in the areas south of the Yangtze River, the background value of heavy metals in the soil is relatively high. The causes of soil heavy metal pollution are very complex. In addition to point source pollution caused by industry, non-point source pollution caused by the abuse of agricultural inputs is also an important reason. At present, the total amount of cadmium entering the soil every year in the world is about 660,000 kg, of which about 55% enters through the application of chemical fertilizers. At the same time, in pursuit of yield and economic benefits, many farmers have replaced organic fert...
