| 摘要: |
| 采用田间试验方法研究爆破成腔技术在旱作农业中的应用，结果表明：爆破成腔技术可在作物根系层土壤中形成稳定的爆破腔体和纵横交错的裂隙，增大作物根系层土壤的透气性；改善旱季农田土壤墒情；增加干旱地区农作物产量。 |

| Abstract: |
| Field experiment is carried out to study the use of cavity making by explosion in arid-agriculture.Results indicate that cavity making by explosion can make a steady blasting cavity and crisscross fissures in the soil in the crop root zone and raise the air permeability of the soil in this zone.Also,it can improve the soil moisture in drought season and increase the crop yield in arid areas. |
| Key words: arid-agriculture technique cavity making by explosion soil moisture soil structure soil permeability |
