不同底肥运筹对稻茬小麦产量构成及氮素利用率的影响
Effects of Different Base Fertilizers on Yield Components, Nitrogen Use Efficiency of Wheat after Cutting Rice
摘要
Abstract
Objective]To research the dosage of different base fertilizers on yield components, nitrogen use efficiency of wheat after cutting rice under the condition of the inshore glue desalting soil.[Method] Huaimai 28, one of the main varieties of Northern Jiangsu, was used to study the effects of different base fertilizers on wheat stem tillers dynamics, yield components, the SPAD value variation after flowering, flag leaf area and nitrogen use efficiency by using the method of randomized block design.[ Result] Higher P fertilizer input played an active role in wheat stem tillers dynamics, yield components, the SPAD value variation after flowering, flag leaf area and nitrogen use efficiency.And 150 kg/hm2 urea+300 kg/hm2 DAP (diammonium phosphate) could obtain the maximum yield and economic benefits.[Conclusion] Under the condition of the inshore glue desalting soil, we must pay more attention to the balance of nitrogen and phosphate fertilization to give full play to the crop production potential.关键词
