通过水稻田间小区试验,分析不同氮肥处理对水稻磷素吸收的影响。结果表明,氮肥施入量过高会影响水稻植株对磷肥的吸收利用。不同的氮肥施用比例及追施次数对水稻吸收磷素有影响,即随着氮肥的增加,磷肥的吸收量有所提高。缓释尿素控制了氮素的释放速度,有利于调节植株吸收磷素,并且间接地提高水稻植株对磷养分的吸收利用。

Through the rice field plot test,analyze the different nitrogen treatment on rice on the absorption of p.The results show that the high nitrogen fertilizer quantity instead of rice plant will affect the absorption of phosphate fertilizer use.Different nitrogen fertilization proportion and to absorb p rice irrigation frequency influence,namely with the increase of nitrogen,phosphate can absorb improved.Slow-release urea nitrogen control the release rate,be helpful for adjusting the plants to absorb the p,and indirectly improve rice plant on phosphorus nutrients absorption and utilization.
