Description

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. 15N tracing showed that Bacillus azotofixans in bio-fertilizer can provided 99.5 mg/ 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. (authors)
