摘　　要：试验以济麦22为材料,采用单因素随机区组设计,以清水为对照,研究固液体聚谷氨酸、氨基酸水溶肥及尿素叶面喷施对晚播冬小麦氮磷钾养分积累和产量的影响。结果表明:不同叶面肥喷施3次均可提高晚播冬小麦的叶绿素含量、干物质积累量、氮磷钾积累量。其中氨基酸水溶肥处理冬小麦产量最高,为4585.6 kg/hm^2,较对照提高50.3%;液体及固体聚谷氨酸处理较对照分别增产47.5%、32.8%,增产效果显著;尿素喷施效果略低但与固体聚谷氨酸处理差异不显著。With Jimai 22 as test material and water as control,the effects of liquid polyglutamic acid,solid polyglutamic acid,amino acid water-soluble fertilizer,and urea on nitrogen,phosphorus and potassium(NPK)nutrient accumulation and yield of late-sown winter wheat were studied by using single-factor random block design.The results showed that spraying foliar fertilizers for 3 times could increase the chlorophyll content,dry matter accumulation,and NPK accumulation of late-sown winter wheat.The yield of winter wheat was the highest under amino acid water-soluble fertilizer treatment,which was 4585.6 kg/hm2 and increased by 50.3%compared with the control.The yield of winter wheat under liquid and solid polyglutamic acid treatments increased by 47.5%and 32.8%,respectively,compared with the control.The effects of spraying urea were slightly lower,but had no significant difference with solid polyglutamic acid treatment.
