摘要: 为明确沧州地区水分对产量及农艺性状的影响,搜集黄淮北片的18个小麦品种进行春季灌水处理,利用室内和田间调查等方法,分析了灌水次数对不同品种的茎蘖动态、叶面积系数、产量等性状的影响。研究表明:浇1水比浇0水的平均增加1021.05 kg/hm2的产量;浇2水比浇1水的平均增加900.00 kg/hm2的产量。在灌浆期对小麦各品种的旗叶叶面积调查发现,0水的叶面积最小,平均为18.15 cm2,浇1水的叶面积为20.34 cm2,浇2水的叶面积最大为24.05 cm2。随着浇水次数的增加,各品种的容重有所下降,不孕小穗数下降,株高逐渐增大。该研究认为在沧州地区每少浇1水,产量损失900.00 kg/hm2。

Abstract: To clarify the effect of water on yield and agronomic characters in Cangzhou area, 18 wheat varieties in the north area of Huanghuai were collected for spring irrigation treatment. The effects of irrigation frequency on tiller dynamics, leaf area coefficient, and yield of different varieties were analyzed by indoor and field investigation. The results showed that the yield of wheat increased by 1021.05 kg/hm2 on average by pouring one time water compared with that of 0 water, and 900.00 kg/hm2 on average by pouring two times water compared with that of one time water. During the grain filling stage, the investigation of the flag leaf area suggested that the leaf area of 0 water was the smallest, with an average of 18.15 cm2, the leaf area of one time water was 20.34 cm2, and the leaf area of two times water was the biggest, 24.05 cm2. With the increase of irrigation times, the volume weight of every variety decreased, the number of spike sterility decreased, and the plant height gradually increased. The study showed that the yield loss was 900.00 kg/hm2 by reducing one time irrigation in Cangzhou area.
