| Abstract: | By analyzing the rainfall use efficiency,the soil moisture variation during the whole growth period,the economic characters and the output of dry-land corn under different film mulch modes,it has been proved that the mode of whole covering on double ridges and planting in catchment furrows is an effective way to store and utilize fully the natural rainfall,to improve soil moisture conservation,to raise rainfall use efficiency,to advance maturity time,and to increase yield and economic benefits of dry-land corn remarkably. |

| Keywords: | dry-land corn rainfall use efficiency film mulch mode |
