摘要
氮素是水稻生长不可缺少的元素之一,对水稻进行氮素诊断,根据诊断结果和栽培目标,及时调整相应施肥措施,实现精准施肥,可最大限度地提高肥料利用率,并减轻环境污染.综述了水稻氮素诊断的发展历史、诊断手段的优缺点、未来氮素诊断发展趋势等多方面内容,分析了穗肥对于水稻产量、产量构成因素和稻米品质的影响,以期充分发挥氮肥效应,为氮素诊断和穗肥追肥提供参考.
Abstract
Nitrogen is one of the indispensable elements for rice growth.Nitrogen diagnosis of rice can timely adjust the corresponding fertilization measures according to the diagnosis results and cultivation objectives,achieve precise fertilization,maximize fertilizer utilization,and reduce environmental pollution.The development history of nitrogen diagnosis in rice,the advantages and disadvantages of diagnostic methods,and the development trend of nitrogen diagnosis in the future were reviewed.The effects of panicle fertilizer on rice yield,yield components and grain quality were analyzed,so as to give full play to the effects of nitrogen fertilizer and provide references for nitrogen diagnosis and panicle fertilizer topdressing.
