根瘤菌对大豆根际土壤微生物及大豆农艺性状的影响
Effects of Rhizobia on Rhizosphere Soil Microoganisms and Agronomic Characters of Soybean
摘要
Abstract
The objective of this study was to investigate the effects of applied rhizobia on dynamic of rhizosphere soil microo-ganisms and agronomic characters of soybean. The numbers of bacteria, fungi,actinomycetes of rhizosphere soil at seedling, flowering,podding,seed filling and mature stage of soybean were determined through colony counting method. Rhizobia increased bacteria number at tested stages of soybean except flowering,and increased fungi number at podding,seed filling,mature stage,and increased actinomycetes number at podding and mature stage of soybean. Rhizobia improved plant height ,main stem nodes,pods per plant and seeds per plant,hence,increased seed yield by 19.44%.关键词
