不同灌溉方式下冬小麦耗水规律及产量的试验研究
Experimental Study on the Water Consumption Characteristic and Yield of Winter Wheat under Different Irrigation Methods
摘要
Abstract
The effects of the traditional flat border irrigation and ridge furrow irrigation on winter wheat yield,water consumption law and water productivity were analyzed.The results showed that:compared with conventional flat tillage,rainfall utilization under the ridge tillage increased by 11.08% ~13.19%;Daily water consumption of winter wheat under ridge tillage furrow irrigation was significantly less than that under conventional flat tillage at the same water treatments;Water consumptions in jointing-heading stage and turning green-jointing stage were the largest under 2 irrigation modes,accounting for about 50%of the whole growth period; Daily water consumption in heading-grain filling stage reached the peak;Water consumption under different treatments increased significantly with the increase of irrigation frequency and irrigation amount while yield and WUE increased first and then decreased;Under the ridge tillage planting mode,irrigation amount reduced by 40% and yield was improved by 392~776 kg/hm2 compared with traditional flat tillage,WUE was the top of 2.08 kg/m3 in treatment of irrigating 3 times.关键词
