摘要
以新疆伊犁树上干杏的6个不同材料(S1～S6)为试材,研究了防冻剂类别、配比浓度及喷施时期对树上干杏坐果率的影响。结果表明:6#树上干杏品系的坐果率最高,适合伊犁河谷区域进行抗寒性栽培研究;防冻液的浓度配比方面500倍液与700倍液对树上干杏坐果率的影响差别不明显,但防冻效果上明显优于300倍液,在防冻剂喷施时期的选择上,在坐果率方面蕾期喷施效果明显优于开花期。表明,提高树上干杏花期抗寒能力,应结合品种选优、授粉树的配置、花期预防低温、施肥和灌水、病虫害防治和防风林的设置及防冻技术应用等各种配套措施实施。
Aimed to test the influence of the antifreeze type,concentration and spraying time on fruit setting rate of dry apricot tree.The anti-freezing experiment was conducted with six different dry apricot tree（S1~S6） in Yili Xinjiang.The results showed that the fruit setting of dry apricot tree 6# was highest and suitable for anti-cold character research in Yili velly.The effect of antifreeze concentration diluted 500 and 700 times had no significantly difference on fruit setting,but the control effecting was more significant than 300 times.About spraying time,the effect of spraying in budding stage was obviously superior in flowering stage.In short,to improve anti-cold character of dry apricot tree,should implement matching measure including species selection,the configuration of pollinizer,preventing low-temperature in flowering stage,fertilizering,irrigating,prevention and control of diseases and pests,windbreaks setting and the application of antifreezing technology.
