文章研究以0.05%力谋仕增效尿素为主要材料,验证其在生产实际中的应用效果,为减少氮肥投入、提高肥效提供依据。研究表明:玉米播种期施用45%(15-15-15)复合肥40kg/亩、拔节期追施0.05%力谋仕增效尿素20kg/亩、土表撒施后15天不灌溉处理产量最高,为905.67kg/亩,氮肥利用率最大,为75.90%,且能够改善玉米生育性状,建议大面积推广应用。
In the article, 0.05% Limeshengzhengliu urea was taken as the main material to verify its application effect in production practice and provide basis for reducing nitrogen fertilizer input and improving fertilizer efficiency. The results showed that 40% of compound fertilizer 45% (15-15-15) was applied in the sowing stage, 0.05% of the compound fertilizer was added at jointing stage and 20 kg / , 905.67kg / mu, the highest utilization rate of nitrogen fertilizer, 75.90%, and can improve maize reproductive traits, it is recommended to promote large-scale application.
