| 摘 要： | 旨在为沧州地区压限采情况下，为限水小麦选育和栽培提供理论依据。本试验利用搜集的河北省10个品种，采用田间调查和室内相结合的方法，分析了灌水量对不同品种的产量及其构成要素、成穗率、株高等性状的影响。结果表明：参试品种的产量均随着浇水次数的增加而增加，三个处理相比较，平均单产达到显著差异(P<0.05)，0水条件下的产量最低为4462.18 kg/hm2，1水条件下的产量为5668.53 kg/hm2，2水条件产量最高为6707.87 kg/hm2。2水处理较1水处理增产18.34%，1水处理较0水处理增产27.03%；小麦穗数、穗粒数、千粒重、成穗率和株高均随着灌水量的增加而增加。在沧州地区一水不浇的情况下，产量损失80~115 kg。

Variation of Yield and Agronomic Characters of Wheat with Limited Water Treatment |
| |
| Abstract: | The aim is to provide references for the breeding and cultivation of wheat under limited water in Cangzhou. 10 varieties in Hebei were used as materials, field investigation and indoor test were combined to analyze the effects of irrigation amount on yield, yield composition, heading rate and plant height of different varieties. The results showed that the yields increased with the increasing watering times, and the average yields of the three treatments were significantly different (P<0.05). The yield of 0 watering was the lowest, 4462.18 kg/hm2. The yield of 1 watering was 5668.53 kg/hm2. The yield of 2 watering was the highest, up to 6707.87 kg/hm2, increased by 18.34 % compared with that of 1 watering, and increased by 27.03% compared with that of 0 watering. The number of ears, the number of grain per ear, 1000-grain weight, ears rate and plant height of wheat increased with the increasing of irrigation amount. In Cangzhou, under no watering, the production lost is 80-115 kg. |
