The invention relates to a rice-
straw antibacterial soil amendment. The rice-
straw antibacterial soil amendment is prepared from the following raw materials in parts by weight: 30-35 parts of rice straws, 20-30 parts of
biochar, 10-15 parts of bean
meal, 5-10 parts of cassava residue, 10-15 parts of
chicken manure, 5-10 parts of
diatom ooze, 2-3 parts of
artemisia argyi, 2-2.5 parts of
glycyrrhiza uralensis, 2-2.5 parts of pine needles, 2-3 parts of
tea tree oil, 2-2.5 parts of
plant ash, 2-3 parts of
zeolite powder, 2-3 parts of microbial functional bacterium agent, 2-3 parts of
sodium benzoate, 1-2 parts of
amino acid, 1-2 parts of
starch and 1-2 parts of molasses
powder. According to the rice-
straw antibacterial soil amendment,
plant wastes are adopted as the raw materials, so that the improvement on quality of soil is facilitated, the production cost can be reduced; the physicochemical properties of the soil are improved, the structure of the soil is comprehensively improved, and the texture of the soil can achieve soft, air-permeable, water-retention and
fertilizer retention effects; and the rice-straw antibacterial soil amendment plays roles in sterilizing, weeding, increasing the utilization ratio of chemical fertilizers, promoting the
root system development of crops, increasing
crop yield and improving product quality.
