灌水对不同小麦品种产量和水分利用效率的影响
Effects of Different Irrigation Patterns on Yield and Water Use Efficiency of Different Wheat Cultivars
摘要
Abstract
Six main wheat varieties locally promoted were studied to explore the water saving cultivation of wheat in northern Henan and to select the outstanding varieties according to their yields under water saving irrigation. The results indicated that the optimal irrigation regime was irrigation at pre-sowing, jointing and flowering stages. The yields of varieties differed between irrigation patterns. In the pre-sowing water pattern(A) , the optimum variety was Zhoumai 22, with the yield of 7 351. 65 kg/ha. In the pre-sowing water and jointing water pattern(B) ,the optimum variety was Zhoumai 22, followed by Luomai 22 and Aikang 58. Their yields were 7 720. 95 kg/ha and 7 677. 30 kg/ha and 7 664. 55 kg/ha, respectively. In the pre-sowing water, jointing water and flowering water pattern(C) ,the yields of Luomai 22,Zhoumai 22 and Aikang 58 were 8190. 15 kg/ha,7 984. 95 kg/ha and 7 910. 70 kg/ha,respectively. The pattern C generated the highest yield and efficiency of using irrigation water,precipitation water and soil water. The ave-rage index values of three varieties were increased by 4. 4% and 17. 0% ,24. 8% and 51. 5%, 4. 5% and 16. 8%,75. 1% and 150. 9%,compared to the patterns B and A. The greatest irrigation water use efficiency was found in the pattern A,and the average values of three varieties was 161.2% and 262. 3% higher than the patterns B and C,which showed that with the increasing of irrigation quantity,the irrigation water use efficiency was decreased.关键词
