摘要
影响根瘤菌竞争结瘤能力的生态因素有土壤条件 ,肥力水平 ,土著根瘤菌的数量和类型 ,其它微生物 ,根瘤菌的接种方式和时间等。在土壤条件方面研究较多的是土壤类型、pH值。肥力水平主要指氮水平和有机质含量。
Factors influencing on the ability of nodulation competition in environment includes soil conditions, level of fertility, the number and type of indigenous rhizobium, other microbes, manner and time of inoculated rhizobium, in addition to other factors. Mostly study of soil conditions influencing on the ability of nodulation competition focus in soil type and pH. Level of fertility includes level of nitrogen and content of organic. This paper would give a brief introduction on this area.
