| 摘 要： | 冀西北高原土壤主要为栗钙土,研究垄、沟覆膜和积聚熟土措施对稀植经济作物小南瓜产量及土壤水分的影响,旨在为栗钙土农田高效生产和农民增收提供科学指导。结果表明:沟覆膜方式能更好地聚集降水和保蓄土壤水分,收获后1 m土体贮水量比播前盈余30.07 mm,比垄膜处理少耗水87.53 mm,水分利用效率(WUE)比垄膜处理高10.20 kg/(mm.hm2)。垄覆膜条件下,聚土使小南瓜产量差异达显著水平(P<0.05)。沟膜条件下,40 cm与60 cm厚度处理产量差异不显著,比20 cm处理分别增产23.01%和25.49%。因此,沟膜+聚40 cm厚度熟土处理,可作为该区旱作高效种植模式,能获得8 277.8 kg/hm2的较高产量。

| Abstract: | A field experiment was conducted in sandy chestnut soil in northwest of Hebei plateau to study the effects of water collection and increasing surface soil thickness on yields of pumpkins and soil water,with the prupose to provide scientific way to produce efficiently and improve peasants' income.The results showed that film mulching on furrow could collect rain and hold soil water effectively.The soil water storage in 0-100 cm layer at harvest was 30.07 mm,more than that at pre-sowing.Compared to film mulching on ridge treatment,the water consumption in mulching over furrow decreased 87.53 mm and the water use efficiency(WUE) increased 10.20 kg/(mm·hm2).The difference of yield with two film mulching treatments was significant(P<0.05).In film mulching on ridge treatment,the difference of yield with altering soil thickness was significant.In film mulching over furrow treatment,the yield of 40 cm and 60 cm soil thickness were not significant with difference,and increased 23.01% and 25.49% than that of 20 cm soil thickness treatment.In the trial,the methods of film mulching over furrow and increasing surface soil thickness to 40 cm may be used as a planting mode for effective dryland production,and reached 8 277.8 kg/hm2. |
