摘要
通过对试验结果的分析,阐述了水稻联合固氮工程菌的不同菌株与化肥及有机肥配合施用对土壤盐分、养分及水稻生长发育中各项指标均有不同的影响,其施肥效果:菌株2>菌株3>菌株1。指出施用联合固氮工程菌是改良土壤,提高产量,促进生态农业发展的有效途径。
The experiment result shows applying different bacterium plants of rice unite nitrogen fixation bacterium combining chemical fertilizer and organic fertilizer influence soil salinity,nutrient and every index of rice development.The applying fertilizer effect:bacterium plant 2>bacterium plant 3>bacterium plant 1.Therefore,this is an effective way to improving soil,increasing yield and developing ecological agriculture.
