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水的处理平均增加产量1021.05 kg/hm~2;浇2水比浇1水的处理平均增加产量900.00 kg/hm~2。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 cm~2,浇1水的叶面积为20.34 cm~2,浇2水的叶面积最大为24.05 cm~2。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/hm~2。
In order to clarify the effect of moisture on yield and agronomic traits in Cangzhou, 18 wheat cultivars from Huanghuaibei were collected for spring irrigation. The indoor and field surveys were used to analyze the effects of irrigation frequency on stem tiller dynamics, leaf area index , Yield and other traits. The results showed that the average yield was increased to 1021.05 kg / hm ~ 2 by pouring 1 water into the treated water as compared with 0 pouring water. The average yield was 900.00 kg / hm ~ 2. The investigation of the flag leaf area of wheat cultivars at the grain filling stage showed that the leaf area of 0 was the smallest, with an average of 18.15 cm ~ 2, the leaf area of 20.34 cm ~ 2 and the maximum of 24.05 cm ~ 2. With the increase of the number of watering, the weight of all varieties declined, the number of spikelets decreased, plant height gradually increased. The study concluded that in Cangzhou area, water was poured at a minimum and the yield loss was 900.00 kg / hm ~ 2.
