摘要
小麦春化特性与抗冻性显著相关,但与抗霜性无关系。因此,在霜冻害频发区推广抗冻力强的冬性、半冬性品种并不能完全杜绝或避免霜冻害带来的损失。采用大田调查方式分析品种抗霜力的结论比较笼统,而采用人工霜箱不但能够准确鉴定冬小麦抗霜力发生跃变的时期,即低温敏感期,而且也是鉴定冬小麦品种抗霜力强弱比较便捷的方法。文章结合国内外研究成果,提出了一系列抗霜对策:选育抗霜品种,优化种植布局;培育壮苗,增强冬小麦抗霜力;通过INA菌和基因工程手段,改良品种抗霜力。
Significantly related to vernalization characteristics and freezing resistance of wheat, but has no relation with the frost resistance, so in frost prone areas to promote strong frost winter and semi winter varieties and can not completely eliminate or avoid frost damage. By the field investigation analysis of frost resistance varieties more general conclusions, but by using the artificial frost box can not only accurate identification of winter wheat frost resistance changing period, namely low temperature sensitive phase, but also the identification method of frost resistance of winter wheat varieties force more convenient. Based on the domestic and foreign research results, put forward a series of countermeasures： breeding resistant varieties, optimizing the layout of planting; seedling cultivation, enhancement of winter wheat frost resistance; By means of INA bacteria and gene engineering, improved varieties of frost resistance.
