摘　　要：为探索新型农林保水剂在旱地冬小麦上的应用效果,在潍坊寒亭、柘山两地安排了小麦保水剂试验。结果表明,在自然条件下,与不施用相比,施用该保水剂45和75 kg/hm 2能有效增加两地小麦的冬前次生根条数、不同时期的干物质重量和分蘖数,进而促进后期形成更多的有效穗数,增加千粒重和穗粒数,最终显著增产24.6%和36.9%。In order to explore the application of new water retaining agent on dryland winter wheat,the experiment was arranged in Hanting and Zheshan of Weifang.The results showed that under the condition of natural rainfall,compared with no application,the application of 45 and 75 kg/hm 2 water retaining agent could effectively increase the number of secondary roots before winter,dry matter weight and tiller number in different periods,promote the formation of more effective panicles in the later period,increase the 1000-grain weight and grain number per panicle,and finally increase the yield by 24.6%and 36.9%,respectively.
