摘要
在农业集约化种植中,土壤质量问题是制约农业生产发展的重要因素,长期连作会导致土壤质量下降,具体表现为土壤物理、化学和生物学性质的变化及微生物群落失衡等.为了解决这一问题,介绍了生物肥料、腐殖质、硅肥、生物炭等常用的土壤改良剂,综述其改善土壤理化性质、抑制土传病害、提高作物产量与品质、调节土壤微生物群落平衡的作用机理及研究进展.
Abstract
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.
