英文摘要	A field experiment was conducted during the 2002/2003 cropping season of winter wheat (Triticum aestivum) and spring maize (Zea mays) to evaluate the effect of limited single drip irrigation on the yield and water use of both crops under relay intercropping in a semi-arid area of northwestern China.A controlled 35 mm single irrigation,either early or late,was applied to each crop at a certain growth stage.Soil water,leaf area,final grain yield and yield components such as the thousand-grain weight,length of spike, fertile spikelet number,number of grains per spike,and grain weight per spike were measured,and water use efficiency and leaf area index were calculated for the irrigated and non-irrigated relay intercropping treatments and sole cropping controls.The results showed that yield,yield components,water use efficiency,and leaf area index in the relay intercropping treatments were affected by limited single drip irrigation during various growth stages of wheat and maize.The total yields in the relay intercropping treatment irrigated during the heading stage of wheat and the heading and anthesis stage of maize were the highest among all the treatments,followed by that irrigated during the anthesis stage of wheat and silking stage of maize;so was the water use efficiency.Significant differences occurred in most yield components between the irrigated and non-irrigated relay-intercropping treatments. The dynamics of the leaf area index in the relay-intercropped or solely cropped wheat and maize showed a type of single-peak pattern,whereas that of the relay intercropping treatments showed a type of double-peak pattern.Appropriately,limited single irrigation and controlled soil water content level could result in higher total yield, water use efficiency,and leaf area index,and improved yield components in relay intercropping.This practice saved the amount of water used for irrigation and also increased the yield.Therefore,heading stage of wheat and heading and anthesis stage of maize were suggested to be the optimum limited single irrigation time for relay-intercropped wheat and maize in the semi-arid area.
