摘要
2013年3月杏树花期遇到0～-2℃低温。在低温来临前,提前喷施300倍微晶蜡液,凯特杏的平均坐果率由13.54%提高到24.49%,珍珠油杏的平均坐果率由9.27%提高到18.35%～24.61%。喷施微晶蜡液可克服花期低温天气影响,明显提高杏树的坐果率。
During March of year 2013, when apricots were blooming in Tai’an region, low temperatures 0～-2℃ were met in two days. Based on weather forecast, 300 × micro-crystal wax solution was sprayed on apricot trees before low temperatures came. After being treated with micro -crystal wax solution, the fruit -bearing rate of Kaite apricot reached 24.49% and that of Zhenzhuyou apricot reached 18.35% ～24.61% ;while both apricot cultivars were not treated, their fruit -bearing rates were only 13.54% and 9.27%,respectively.
