摘要

A biological soil amendment for coastal saline-alkali soil, comprising the following components in parts by weight: 1-2 parts of sludge powder, 0.25-2 parts of charcoal powder, 0.1-1 part of rice hull powder, 4-15 parts of water, and 0.5-1 part of high salt tolerant microbial bacteria liquid. The biological soil amendment is simple in preparation process and low in cost, can rapidly increase the soil fertility to effectively improve the current situations of the coastal saline-alkali soil such as low fertility, high sand content and poor soil aggregate structure, increase the soil humus, and facilitates formation of aggregate structures, and organic acid generated after decomposition of the biological soil amendment can neutralize the alkalinity of the soil without contaminating the soil, the plough layer salt accumulation condition can be relieved, and commercial crop growth is facilitated.
