摘要
在盘山县对水稻进行缓释尿素和磷、钾肥做基肥一次施入免追肥试验和示范研究,结果表明,缓释尿素可提供水稻整个生育期的氮素供应,该施肥法可确保水稻产量,省工省事,可以大面积推广应用。
The effect of basal application of slow-release urea combined with P and K fertilizers but without top-dressing on rice growth was conducted in Panshang County, Liaoning Province of China, with plot and demonstration trials. The results showed that there was no significant different between slow-release urea treatment and conventional fertilization treatment. However, basal application of slow-release urea without top-dressing could supply enough N during the rice growing stages, guarantee rice yield and save labor force. It is suggested that the slow-release urea could be popularized in rice production in the study region.
