补充资料:如何让花卉安全度夏
    温度是影响花卉生长的关键因素,夏季强光和高温容易导致花卉被灼伤,影响其生长。若想使花卉安全度夏,应做好以下几项措施。
    一、避光控温在7至9月的夏旱酷暑季节,将花圃内的花用遮阳网遮阴,或将花盆移至阴棚、树荫下或通风良好无强光直射的室内,保持通气的散射光条件,防止强光暴晒,降低温度。
    二、喷水降温温度除受光照影响外,与水分变化密切相关。水有吸热的功能,所以,喷水有降温作用。夏秋高温期干旱缺水,容易造成植物细胞脱水,引起萎凋,严重时植株枯死。在高温干旱时期,要加强灌溉,及时浇水,或在植株周围地面喷水、垫湿草、叶面喷雾,提高土壤与空气湿度,降低温度。但是浇水要在早晚进行。
    三、激素调温高温期喷洒750ppm多效唑、1500ppm青鲜素或1500ppm至2000ppmBy等生长抑制剂加O.1%至0.2%磷酸二氢钾,可抑制植株徒长,加速枝叶细胞成熟,增强抗逆性,缓解高温热害。结合浇水,浇灌或喷洒阿司匹林(1千克水溶解1片),可促进叶片气孔的闭合,减少叶片水分的蒸腾散失,减少高温灼伤。(来源:中国花卉报2003-06-10)
