| 摘 要： | [目的]为了研究控释氮肥的控释性能。[方法]通过田间试验,研究2种控释氮肥在玉米和大白菜上的施用效果和对土壤氮素养分的影响。[结果]控释肥一次施入肥效明显地优于常规施肥,与多追施10%氮效果相近,玉米生物产量分别比常规施氮增加8.8%和5.2%,PK包膜尿素的控释效果比MFSU-Xin包膜尿素好。控释肥可明显提高氮肥的利用率,PK和MFSU-Xin控释肥利用率分别比常施肥提高89.2%和53.2%。[结论]控释肥可以增加土壤后效,为下季作物提供较多氮素。

| Abstract: | [Objective] The research aimed to study the controlled-release character of controlled-release N fertilizer.[Method]Effects of controlled-release N fertilizers on the growth of maize and chinese cabbage and soil N content were studied through a field experiment.[Result] All controlled-release N fertilizers were basal applied,which were better than conventional fertilizer used,and the same as more 10% N used.And corn biological yield were 8.8% and 5.2% higher respectively.Controlled-release effect of PK were... |
