摘    要:通过水稻盆栽试验对生物肥肥效研究结果表明,复混生物肥能提高肥料对水稻的养分供应能力,提高茬后土壤速效养分含量。15N示踪法研究结果表明,固氮菌的固氮作用,能为当季水稻提供氮素99.5mg/盆,占水稻总吸收氮的11.92%。同时微生物的作用,还能减少肥料氮的损失,提高肥料氮的回收率。

关 键 词:复混生物肥    灭菌生物肥    水稻

Abstract:The experimental study on the effects of bio-fertilizer on pot planted rice showed that bio-fertilizer could promote the nutrient supply for rice. In addition, the nutrient content in soil after harvesting was increased through the application of bio-fertilizer. ()~(15)N tracing showed that Bacillus azotofixans in bio-ferfilizercan provided 99.5mg/plant azote for rice, which was about 11.92% of the total azote absorption. At the same time, micro-organism could decrease the loss of the azote, thus increasing the recovery rate of azote.
Keywords:compound bio-fertilizer  sterilized bio-fertilizer  rice
