| 摘 要： | 通过对"大垄双行覆膜+膜下滴灌+垄向区田"和"行间覆膜+露地滴灌+垄向区田"两种集成模式条件下的玉米产量、经济效益以及水分利用效率的研究,结果表明:"大垄双行覆膜+膜下滴灌+垄向区田"集成模式从产量、经济效益和水分利用效率均好于"行间覆膜十露地滴灌+垄向区田"集成模式;利用RAGA-PIC模型对集成模式进行评价,各个指标的贡献率大小顺序依次为:产值,经济效益,水分利用率,玉米产量和投入费用,其中B2处理表现最好,为抗早节水提出了新的思路.

| Abstract: | Research is done on maize yield,economic benefits and WUE by means of the 2 integration models,which are film-mulching of double line width ridge+drip irrigation under mulch+ridge tillage and covering film between furrows+ drip irrigation+ridge tillage.The results show that film-mulching of double line width ridge+drip irrigation under mulch+ridge tillage are better than another integration model in maize yield,economic benefits and WUE;evaluation on integration models with RAGA-PPC model,getting sequence o... |
