温州蜜柑盛花期与幼果期喷施“5406”菌的代谢产物(200～400倍Ⅱ号粉剂),能显著提高座果率,增加单果重10.3～15.5％,单株产量增加25.8～34.9％,果实品质也有所提高。在研究影响柑桔落果的各种因子中,曾发现座果的高低与激素水平相关,当内源激素水平降低时,应用外源激素能不同程度地控制果实的脱落。在应用激素方面,已证明GA对增进座果有良好的效果,生长素与细胞分裂素也对果实脱落有强烈的抑制。
In the flowering stage and juvenile stage, the metabolites (200 ~ 400 times of Ⅱ powder) of “5406” bacteria were sprayed at the flowering stage and young fruit stage, which could significantly increase the fruit set percentage, increase the fruit weight 10.3 ~ 15.5%, and increase the single plant yield 25.8 ~ 34.9% , Fruit quality has also improved. In studying the various factors affecting the fall of citrus fruits, it has been found that the height of the fruit is related to hormone levels. When the levels of endogenous hormones are reduced, exogenous hormones can control the fruit shedding to varying degrees. In the application of hormones, GA has been shown to improve the fruit has a good effect, auxin and cytokinin also fruit strongly off.
