近年来,国内外农学家、土壤学家和微生物学家对作物根际的微生物群作了很多有意义的研究工作.他们发现,根际微生物群是一个十分复杂的微生物社会。它们之间存在着互助共生、抑制平衡、拮抗共济等复杂的生物群落关系。所有这些复杂多样的关系,有一个必不可少的前提,即根际必须提供多种微生物能健旺生活繁殖的环境.这种环境,除了水分、空气而外,丰富的有机物质是决不可少的. 人类从古时起,就一直在使用堆厩肥,它既能提高作物产量又能改善土壤的理化性状.所谓堆厩肥就
In recent years, agronomists, soil scientists and microbiologists at home and abroad have made a lot of meaningful studies on the microbial population in the rhizosphere of crops, and they found that the rhizosphere microbial community is a very complex microbial society. Between them there are mutual aid and symbiosis, balance inhibition, antagonism and mutual aid complex biological community. It is an indispensable prerequisite for all these complex and diverse relationships that the rhizosphere must provide a rich environment in which microbes can flourish and live, an environment where abundant organic matter is essential except for moisture and air Since ancient times, mankind has been using heap manure, which can improve crop yields and improve physical and chemical properties of soils.
