影响微生物接种剂发挥作用的因素

大量施用化肥不仅造成了环境污染, 而且也是一个能源消耗的问题。在生态农业中, 通过向土壤中接种有益微生物部分替代化肥已是科学家研究的热点。微生物通过活化土壤养分、抑制病原菌、降解有毒污染物等方式发挥作用, 然而, 微生物要发挥功效必须在土壤中能够定殖。本文主要针对国内外在影响微生物根际定殖的因素以及影响引入微生物活性的因素两方面的研究进行综述, 同时强调对接种剂引入所引起的生物种群及生态环境变化应予以重视。

Factors Affect Efficiency of Bacterial Inoculation

The mass utilization of chemical fertilizer not only is a problem of environment, but also an energy issue. To inoculate beneficial microorganisms has been the topic of scientist to cope with it. The bacteria achieve the goal through the way of dissolving nutrients unavailable, restraining pathogeny, reducing deleterious compounds and so on. However, it should be colonized in soil first to realize its function. This paper summarized factors, both in biologic and abiological aspects that affected successful colonization and activity of bacterial inoculation. The impacts of inoculated bacteria on population structure of specific rhizobacterial communities and environment should also be paid an eye on.
