在小麦生长季节降雨量很少的地区,必须选育抗旱性强的品种。据有关报道,在干旱地区种植抗旱性强、生态型和环境条件相适应的小麦良种,一般比不适应的类型品种增产10～20％。适应自然的特点,选育抗旱性品种是增产的重要措施。而选育抗旱品种,首先应对抗旱品种的特征特性有充分的了解。据笔者多年观察和资料分析,冬小麦抗旱品种的生态生理一般具有以下特点:
In areas where there is little rainfall in the wheat growing season, we must breed drought-resistant varieties. According to reports, growing wheat varieties with drought-resistant, ecotype-based and environmental conditions in dry areas generally yields 10-20% more yield than non-adapted varieties. Adapt to the characteristics of nature, breeding drought-resistant varieties is an important measure to increase production. Breeding drought-resistant varieties, first of all, to deal with the characteristics of drought-resistant varieties have a full understanding. According to the author for many years of observation and data analysis, ecological management of winter wheat drought-resistant varieties generally have the following characteristics:
