摘要
[目的]结合当前控失肥应用现状及氮素肥料特点,研究控失尿素在潮土区小麦生产中的应用效果.[方法]以常规施肥为对照,将控失尿素不同用量(磷钾与常规施肥相同)作为处理,研究不同用量控失尿素对小麦的增产增效作用.[结果]与普通肥料相比,施用控失尿素对小麦生育期无明显影响;对生物学性状和产量构成因素有明显影响,株高、旗叶长、穗长、结实率、穗粒数、千粒重增加,穗数略有减少;增产效果明显,节肥、增效显著.[结论]控失尿素对小麦增产、节肥、增效作用明显,适用于潮土区小麦生产.
Abstract
[Objective] Combined with application status of loss control fertilizer and nitrogen fertilizer characteristics,the application effect of loss control urea on wheat production in moisture soil area was studied.[Method] With conventional fertilization as the control,urea in different dosage (P,K was the same with conventional fertilization) were treated to study effects of loss control urea on yield,efficiency increasing of wheat.[Result] Compared with common fertilizer,loss control urea had no obvious effects on wheat growth period,but it had significant influence on wheat biological traits,plant height,flag leaf length,spike length,seed-setting rate,grain number per spike,1 000-grain weight was increased,spike number was reduced;yield increasing,fertilizer-saving and efficiency increasing was obvious.[Conclusion] Loss control urea has obvious effect on wheat yield increasing,fertilizer saving and efficiency increasing,which is appropriate for application in wheat production in moisture soil region.
