| 摘 要： | 采用正交试验方法，研究爆破成腔技术在干旱地区农田土壤蓄水保墒和增产中的效应。结果表明：爆破成腔技术是提高干旱地区农田土壤调蓄降水能力、改善旱季农田土壤墒情的有效措施，可使干旱地区农田在100cm深度内的蓄水量增加10%～37%左右，无降水时间越长增加幅度越大，冬小麦平均增产28%。

| Abstract: | Orthogonal experiment method is applied to study the effectiveness of cavity-making by explosion technology in soil water preservation in arid area. The result shows that this technology can elevate the water storage capacity of soil and improves soil moisture in dry season. The amount of water storage at the depth of 100cm increases by 10%-37%. The longer the period of without precipitation, the greater incremental amplitude of yield elevated. The winter wheat yield can be incresed by 28%. |
