Research progress and prospects of soil activation technology
In intensive agricultural cultivation,the problem of soil quality is an important factor restricting the development of agricultural production.Long-term continuous cropping will lead to the decline of soil quality,which is manifested in the changes of soil physical,chemical and biological properties,as well as the imbalance of microbial communities.In order to solve this problem,soil conditioners,such as biofertilizers,humus,silica fertilizers,biochar and other substances were applied,which could directly improve the soil physicochemical properties,inhibit soil-borne diseases,improve crop yield and quality,and regulate the balance of soil microbial communities.In this paper,the mechanism of action,the progress of application of several commonly used soil amendments to activate the soil were introduced in detail.
