| Abstract: | The paper aims at the problems of longterm water shortage and deficit to crop production in dryland region. The yield response to limited water supply at the key stages for water requirement of several crops and water-conserving mulches was experimented for full use of limited rainfall resource with high efficiency. The results indicated that the limited water supply has a very high efficiency and plays an important role in raising economic yields. The technical pathway for limited rainfall resource enrichment,piling up and high efficiency use to construct farmland with high yield and efficiency in dryland region is presented. |
