摘要: 了解喷施植物复合叶肥“绿荣追施宝”对小麦产量的影响及喷施的最佳时期,为小麦生产上的应用提供参考。以‘晋麦84’为试材,小麦起身后不同时期喷施,进而分析籽粒灌浆特性及产量因素。结果表明:在“常规施肥+抽穗期+灌浆期”和“常规施肥+拔节期+抽穗期+灌浆期”喷施“绿荣追施宝”皆能显著延长小麦的灌浆持续时间,获得较大的穗粒数、单株成穗数、千粒重,进而显著提高小麦产量,尤其在拔节期、抽穗期和灌浆期各喷施一次效果更好。建议小麦生产中,除常规施肥外,拔节期、抽穗期、灌浆期各喷施一次“绿荣追施宝”,喷施浓度为800倍稀释液。

Abstract: The aims were to study the effects of“Lurong”on the yield of wheat, determine the optimal spraying period, and provide reference for wheat production. Wheat variety,‘Jinmai 84’was sprayed with a new compound foliar fertilizer“Lurong”at different stages after standing, then the characters of grain filling and yield components were analyzed. The results showed“base fertilizer heading spraying grain filling spraying ”and“base fertilizer jointing spraying heading spraying grain filling spraying”could prolong grain filling, and increase grain number per spike, spike number per plant and thousand kernel weight, further increased wheat yield. Specially, the result of spraying the foliar fertilizer at jointing, heading and grain filling stage individually had the best effect. It was suggested that the foliar fertilizer“Lurong”with 800 times dilution should be sprayed at jointing, heading and grain filling stage in wheat.
