| 摘 要： | 采用L4(23)正交表做1/2实施试验，研究爆破成腔技术在黄土高原土壤蓄水保墒中的作用。结果表明：爆破成腔技术是提高该地区农田土壤蓄水能力、改善旱季农田土壤墒情的有效措施；爆破成腔技术可使黄土高原农田在100 cm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。

| Abstract: | An orthogonal experiment was carried out by L4(2 3) orthogonal array to study the function of cavity making by explosion in water storage and soil moisture holding in loess field. Results indicate that cavity making by explosion is an effective measure to enhance the capacity of soil precipitation in arid field and to improve the soil moisture in drought season; Cavity making by explosion can increase the water storage by about 10%~37% in arid area at the depth below 100 cm, the longer the period without precipitation is, the greater the incremental amplitude is. |
