| Abstract: | The paper puts forward the quota for additional irrigation, numbers of irrigation and effects of irrigation for different crops in different periods based on the basic characteristics of collected rain sources in semi-arid area of the loess plateau in the middle-east of Gansu. It is shown by tests and study that to provide additional irrigation in the key period and after drought for main crops in the non-irrigated area will receive remarkable effects on increasing production, keeping a full stand of seedling, stable yields and notable increase of efficient of water utilization and supply. |
