| A comprehensive overview is made on the yield-increasing mechanism and effect of crop root-zone water micro-collecting farming in arid regions of China. Based on existing research, there still existed a number of issues in the current root-zone water micro- collecting farming technology research so the studies on improving and strengthening the technology's impact on crop productivity and water and fertilizer coupling mechanism were put forward. Moreover, we should make a scientific evaluation on the effect of application and water and soil conservation of root-zone water micro-collecting farming under different rainfall. And it is important to further standardize the related technical standards and procedures of root-zone water micro-collecting farming. On the basis of further experimental study and extensive demon. stration, we concluded that the technology would be very widely used in anid areas, which would be an important way of improving resource efficiency for precipitation and increasing crop yield in arid areas. |
