The experiments of fertilizer effects between controlled release urea(CRU) and common urea on summer wheat Zhengmai 366 are studied.
采用控释尿素和普通尿素两种氮素肥料进行优质小麦郑麦366肥效试验研究。
The releasing rules of controlled-release urea were investigated by fluorescence photometry method, also yield and fertilizer-saving effects in wheat fanning were examined.
以紫外分光光度法对控释尿素的释放规律进行了测定，结合大田试验考查了控释尿素的增产、节肥效果。
The result showed: Among all examined fertilizers, the nutrient release rate of urea was the highest and that of controlled release nitrogen fertilizer was the lowest.
研究结果表明：控释氮肥养分释放速率最低、肥效最长，与尿素相比可改善运动场草坪的外观品质；
