Abstract

The invention discloses a soil conditioner with bamboo charcoal and a method for preparing the soil conditioner. The soil conditioner comprises, by weight, 40-60% of bamboo charcoal powder, 10-30% of organic acid, 10-20% of quicklime powder, 5-10% of diatomaceous earth, 5-10% of urea and 0.5-2% of ferrous EDTA (ethylene diamine tetraacetic acid). The soil conditioner and the method have the advantages that the soil conditioner contains abundant stable-state organic carbon, accordingly, organic matters in soil can be effectively increased, emission of greenhouse gas N2O can be reduced, heavy metal and pesticide residues in the soil can be adsorbed and passivated, soil structures can be improved, and the microbial biomass and diversity of the soil can be improved; the potential of hydrogen of the soil can be regulated, the air permeability and the water retention of the soil can be improved, and phosphorus and potassium elements in the soil can be activated; the soil conditioner is low in usage and production cost and convenient to use and is green and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of agricultural chemicals, and in particular relates to a bamboo charcoal soil conditioner and a preparation method thereof. Background technique [0002] In recent years, with the continuous acceleration of the industrialization process, the irrational mining of mineral resources and their smelting discharge, long-term sewage irrigation and sludge application to the soil, atmospheric deposition caused by human activities, and the application of chemical fertilizers and pesticides have caused The soil is seriously polluted. [0003] According to the 2015 soil pollution survey, there are 320 seriously polluted areas in my country, covering about 5.48 million hectares. In addition, there are at least nearly 30 million hectares of polluted land in my country, including nearly 20 million hectares of cultivated land polluted by heavy metals, 5 million hectares of land polluted by oil, 2 million hectares of land polluted b...
