摘要/Abstract

摘要： 根据山东省桓台县农业水资源日趋减少的现状,开展了以减少土壤水蒸发、提高水分利用效率为目的的不同培肥措施的节水田间试验.结果表明,秸秆还田与增施有机肥具有明显的节水增产效应.在相同灌溉水量(250mm)的情况下,玉米秸与小麦秸全部还田较玉米秸小麦秸均不还田(对照)增产 885kg·hm^-2,水分利用效率提高 3.13,在全还基础上增施有机肥较对照增产 1875kg·hm^-2,水分利用效率提高 3.60;仅小麦秸全部还田较对照增产 675kg·hm^-2,水分利用效率提高3.24,在麦秸还田基础上增施有机肥较对照增产1200kg·hm^-2,水分利用效率提高3.28.

Abstract: Water resource in agriculture in Huabei Plain has been increasingly reduced in recent years.In order to reduce water evaporation and improve water utilization efficiency, the field experiment on water saving under different soil fertility improvements was carried out in Huantai county,Shandong Province.The result showed that straw incorporation and organic fertilizer application could increase yield and save water clearly.Under the same amount of irrigation(250mm),the field with all corn and wheat straw incorporation had a higher yield of 885kg穐m^-2 than the field without straw incorporatiion, and a higher water efficiency of 3.13.The field with all corn and wheat straw incorporation and organic fertilizer application had a higher yield of 1875kg穐m^-2 than the comparing field, with a higher water efficiency of 3.60.The field with wheat straw incorporation had a higher yield of 675kg穐m^-2 than the comparing field,with a higher water efficiency of 3.24.The field with wheat straw incorporation and organic fertilizer application had a higher yield of 1200kg穐m^-2 than the comparing field, with a higher water efficiency of 3.28.
