Abstract

The invention discloses a soil conditioner. The soil conditioner comprises 58-62 wt% of biochar, 15-17 wt% of pyroligneous acid, 21-23 wt% of seashell powder, 0.2-0.4 wt% of borax, 0.2-0.4 wt% of zincsulfate, 0.2-0.4 wt% of magnesium sulfate, 0.05-0.2 wt% of ammonium molybdate and 0.9-1.2 wt% of a binder. A preparation method of the soil conditioner includes the following steps: weighing, pulverizing, mixing, gelatinizing and drying. The soil conditioner is very friendly to the soil environment and crops, has no secondary pollution to the environment, effectively increases the content of organic matters in the soil, improves the problems of acidification, hardening and serious heavy metal pollution of soil, and realizes the sustainable development of the agriculture.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner and a preparation method thereof. Background technique [0002] Over the years, with the reduction of cultivated land area, the problems of excessive use of soil resources, insufficient rural labor force, and excessive use of chemical fertilizers have become prominent, resulting in local soil compaction, acidification, reduction of organic matter content, degradation of cultivated land quality, and even local heavy metal pollution. This phenomenon has seriously affected the quality of agricultural products and food security. [0003] At present, the improvement of soil mostly uses soil improver, but the widely used acidic soil improver in the prior art is slaked lime, though long-term application of slaked lime in large quantities has improved the acidity of soil, also can kill a large amount of soil microorganisms, and slaked lime and Air CO 2 and w...
