Abstract
The objective of current study was to investigate the effects of controlled-release fertilizer treatments on rhizosphere soil microorganisms,soil fertility and agronomic characters of soybean.Four fertilizer treatments,including no fertilizer(CK),conventional fertilizer(CF),controlled-release urea(CRU) and controlled-release compound fertilizer(CRF)were adopted.The numbers of bacteria,fungi,actinomycetes of rhizosphere soil at pre-sowing and maturity were determined through colony counting method;the change of rhizosphere soil microorganisms,soil nutrient content,soybean agronomic characters as well as yield components were investigated.Compared with CK and CF,the numbers of bacteria,fungi,actinomycetes as well as soil fertility were obviously increased under CRU and CRF.The effect of CRF was better than CRU in terms of soil bacteria number and soil fertility.CRU and CRF didn't show significant advantage for agronomic characters and yield components of soybean.Compared with conventional fertilizer,controlled-release fertilizer could increase the numbers of soil microoganisms,improve soil fertility and fertilizer efficiency,hence reduce fertilizer pollution on the environment.
