Abstract:
Surge irrigation is a good measure to solve problems of low irrigation uniformity and large deep leakage in long border fields.However,application area of surge irrigation in China is not optimistic.Based on field experiment in Minqin area of Wuwei City,Gansu Province,two spring wheat varieties were selected,and irrigated by surge irrigation and segmented irrigation at the field with long border,to validate adaptability of surge irrigation and segmented irrigation for long border field in northwest arid area.Experimental results showed that surge irrigation and segmented irrigation were suitable for wheat production in Minqin area,and could be used as a specific water-saving irrigation measure of border irrigation for spring wheat in this area.The results can provide technical support for extension of water-saving irrigation in long border field for wheat in the northwest arid area of China.
