张家口地区冬麦春播的生育表现及其田间春化条件的研究

The Growth Experiment and Conditions of Field Vernalization of Spring Sowing to Winter Wheat in Zhangjiakou Area

以冬性小麦在张家口地区春播试验为依据,阐明了冬性小麦品种在张家口地区能够通过春化反应正常成熟,为本地区利用冬性品种,解决降水集中盛期和春麦需水盛期不吻和的矛盾,提供了可行性依据。同时也表明:低温并非冬小麦田间春化的唯一条件,较宽的温度范围和较短的日照长度相组合,也能保证田间春化的顺利通过。

The results of the spring sowing of winter wheat in Zhangjiakou area showed thatthe winter wheat can reach a normal maturity with vernalization in Zhangjiakou area. andthis provided the possibility basis on how to utilize winter wheat in Zhangjiakou area and onhow to solve the contradiction of the full concentrate precipitation period is out of accord withthe full water requirement period of winter wheat. The success on spring sowing of winterwheat also proved that low temperature is not the only condition of field vernalization, andthat the combination of winter temperature range with shorter day length can also guaranteesfiled vernalization of winter wheat.
