FACILITY SECONDARY NITRATE ION SALINIZED SOIL MODIFIER, PREPARATION METHOD AND MODIFICATION METHOD

摘要

A second nitrate-modified facility soil remediation agent and an improved method are disclosed. The present invention includes a method for producing two kinds of biological soil modifying agents A and B and a method for spraying the same, and a specific description thereof is as follows: (1) Soil modifying agent A: As a solid, a raw material such as rice straw powder and rice bran, Fermentation, the C / N ratio is between 30 and 50, and the spraying method is uniformly mixed with the cultivated soil at 1-1.4 ‰ in mass ratio, aged at 35-50 ° C for 5-7 days, Spray. (2) Soil modifier B: A liquid which is subjected to a purification process to retain salt-tolerant microorganisms and is used for the growth period of crops. Based on microbiological techniques, the present invention can improve the soil structure, improve microbial activity, promote biological nitrogen fixation of the inorganic nitrogen in the soil, and reduce the nitrogen content of the soil in the soil, Greatly increases the yield and improves the quality of the product.
