摘    要:目的]验证“美洲星”叶面肥对小麦的增产效果。方法]通过不同小麦品种的应用效果试验,研究美洲星对小麦产量3要素及产量的影响;通过不同时期的应用效果试验,研究美洲星对小麦产量3要素及产量的影响。结果]不同小麦品种喷施“美洲星”叶面肥后的穗粒数、千粒重有所增加,穗数变化不大,小麦生育后期喷施“美洲星”具有一定的增产作用,8个品种平均增产2.4%;不同喷施时期都使小麦的穗粒数、千粒重有所增加,有效穗数变化不大;产量以喷施3次处理最高。结论]在小麦生长的中后期,喷施美洲星复合液肥,具有一定的增产作用,增产幅度在6%左右,在小麦拔节、孕穗、灌浆期各喷一次,效果更好。

关 键 词:小麦  叶面喷肥  美洲星

Abstract:Objective] The yield-incoreasing effect of leaf fertilizer was verified.Method] Effects of 3 yield factor and yield on wheat by spraying meizhouxing were studied by experiment on using different wheat varieties.And the effects of that were studied by experiment on using different period.Result] Grains per spike and 1 000-grain weight increased and little changed in spike by spraying Meizhouxing for different varieties.Spraying it in late wheat had a certain role in the production,which increased by 2.4% ...
Keywords:Wheat  Leaf spraying fertilizer  Meizhouxing
