不同供肥措施对强筋小麦灌浆特性和产量构成的影响

目的]研究不同供肥措施对强筋小麦灌浆特性和产量构成的影响,找到较理想的强筋小麦高产栽培措施。方法]以郑麦366为供试品种,设置5种供肥措施。结果]在常规施肥的基础上,秸秆还田和增施有机肥可以提高强筋小麦的灌浆速率,延长灌浆时间,有利于小麦成穗数、穗粒数、千粒重的增加,进而提高小麦产量。结论]秸秆还田和增施有机肥对提高强筋小麦产量有促进作用,在5种处理中优化施肥方式的效果最为明显。

Effects of Different Measures for Fertilizer on Grain Filling Characteristics and Grain Yield Components of Strong Gluten Wheat

Objective]The research aimed to study grain filling characteristics and grain yield of strong gluten wheat at different measures for fertilizer,and find the ideal high-yield cultivation measures of strong gluten wheat.Method]Zhengmai 366 was taken as materials,and five different measures for fertilizer were set.Result] Straw returning and the application of organic fertilizer could improve the grain filling rate of the strong gluten wheat on the basis of conventional fertilization,extend the grain filling time,and were beneficial to increase wheat ears,ear mumber,grain weight,thus improve the yield of wheat.Conclusion]Straw returning and the application of organic fertilizer could improve the yield of wheat,and the effects of optimum fertilization was the most obvious in the five treatment.
