摘    要:通过试验研究,秋冬至初春连旱对冬小麦产量有着重要的影响。在底墒水充足,肥料施用量适当,播种期和播种量适宜的情况下,遇秋冬季降水量距平百分率严重偏少,在冬小麦孕穗期-抽穗期形成大气干旱,短期内土壤干旱时,灌溉可使地上部干物质重量和鲜重增加,总茎数增多,但冬小麦实际产量增加不明显。当气象部门预报后期有适量降水时,不需要浇水,以避免造成水资源浪费,增加生产成本。

关 键 词:干旱  冬小麦  产量

Abstract:Through the experimental research,the consecutive drought from autumn-winter to early spring had an important impact on winter wheat yield. There was adequate moisture in the bottom,fertilizer application amount due,the amount of planting and seeding appropriate circum-stances,the percentage of the autumn-winter precipitation was less seriously than normal. In the winter boot stage-heading the formation of atmospheric drought,soil drought. In the winter boot stage-heading the formation of atmospheric drough...
