早熟温州蜜柑春梢老熟与幼果稳果期相吻合,造成梢、果彼此争夺养分,致使幼果养分不足而大量脱落。为提高坐果率,生产上普遍采用人工抹梢进行保果,但费工费时。为减少工作量,我们于1991年至1992年,连续两年应用广西临桂综合化工厂生产的广增素(802)在早熟温州蜜柑上进行初试和中试,均取得了显著的控梢保果效果。 初试结果,用药浓度100、150、200ppm的平均梢长分别为3.9、3.7、4.0厘米,而对照(不喷药)平均梢长为9.5厘米,处理树比对照树将近缩短两倍。三种不同浓度的药液处理树,
Early maturity of Wenzhou Satsuma mandarin spring ripe old fruit and young fruiting period consistent, resulting in shoots, fruiting each other for nutrients, resulting in lack of nutrients and a large number of young fruit off. To improve the rate of fruit set, the production of commonly used artificial wipes for fruit, but time-consuming work. In order to reduce the work load, we used Guangnansuogen (802) produced by Guangxi Lingui General Chemical Plant for pilot and pilot tests on early maturity Satsuma mandarin from 1991 to 1992 for two consecutive years, both of which achieved significant control measures Fruit effect. The initial test results showed that the average shoot length at the concentrations of 100, 150 and 200 ppm were 3.9, 3.7 and 4.0 cm, respectively, while the average shoot length of the control (no spray) was 9.5 cm. Three different concentrations of liquid treatment tree,
