对泰兴市40年(1959~1999年)的气象资料分析表明,近10年来麦作期间气候明显变暖,导致小麦生育进程加快,拔节提前,春季冻害的频率提高。对策是:①调迟播种日期,以推迟小麦拔节;②降低群体起点,培育健壮个体;③多效唑、矮苗壮拌种、化控,适时适度镇压,控旺促壮防冻害;④冻后迅速补肥减少损失。
The analysis of the meteorological data of Taixing for 40 years (from 1959 to 1999) shows that the climate has been obviously warmer during the wheat cropping in the recent 10 years, leading to the accelerated growth of wheat and the earlier jointing and the increased frequency of frost damage in spring. The measures are: ① delay the sowing date to postpone the wheat jointing; ② reduce the starting point of the group, to develop robust individuals; ③ paclobutrazol, seedling Zhuang Zhuang, chemical control, timely moderate suppression, prosperous Zhuang Zhuang frost damage; Make up fertilizer to reduce losses.
