摘要
酸性紫色土大豆施用溶磷菌(水剂)的试验结果表明:与常规施肥比较,土壤中有效磷含量提高16.04%;大豆植株分枝数、株高、每株有效结荚数明显增加;最低结荚位明显降低,百粒鲜豆重明显增加;大豆单产提高7.87%,纯收入显著增加,产量增加达极显著水平;对土壤无污染,生态效益好。
Applying phosphate-solubilizing bacteria （water） to acid purple soil where planted soybean to conduct experiment. The results showed that the content of available phosphor in soil increased by 16.04%; the branch number, the plant height, the effective pot-setting number per plant and the fresh weight of bean increased obviously; the lowest pod position reduced obviously, but the fresh weight of 100 beans increased significantly; unit yield of soybean increased by 7.87%, the pure income increased significantly, and the yield-increasing reached significant level; this treatment had no pollution on soil and has good ecological benefit.
