不同控释氮肥对玉米产量和氮肥利用率的影响
Effects of Different Controlled-release Nitrogen Fertilizer on Yield and Nitrogen Utilization Rate of Maize
摘要
Abstract
[ Objective] The aim was to provide a theoretical fouhdation for wide utilization of controlled-release nitrogen fertilizer in maize field.[ Method ] Field plot experiment was conducted to compare the different controlled-release nitrogen fertilizers on yield and nitrogen utilization rate of maize. [ Result] The highest yield and nitrogen utilization rate of maize was applied of controlled-release polyolefin-coated urea. Nitrogen utilization rate was increased signifieantly by 4.99％ to 14.54％ by the applying of controlled-release nitrogen fertilizer. [ Conclusion] Controlled-release nitrogen fertilizer could increase nitrogen utilization rate of maize significantly, controlled-release polyolefin-coated urea had a best effect on maize.关键词
