近年来我省柑桔产量连年上升,但仍存在着大面积单产低,结果株数比重小,还有相当一部分幼树应结果而未结果或少结果。虽采用了环割、断根、扭梢、喷布激素等保果措施,但对一些树势偏旺的幼树效果并不显著。我们于1984年进行了锦橙抹除部分春梢保果试验,取得较好效果。试验结果:以锦橙抹除总枝数二分之一春梢的效果最好,座果率为6.63％,较对照高29.5％;抹除总枝数三分之一春梢的座果率为5.61％,较对照高9.6％;全部抹去春梢的座果率为6.41％,较对照高25.2％。可见抹春梢也要因地制宜。对
In recent years, the output of citrus in our province has been increasing year by year, but there are still a large area of low yield, the result of the proportion of small number of trees, there are a considerable number of young trees should be results without results or less results. Although the use of the ring cut, cut the root, twist tip, sprayed hormones and other fruit measures, but for some tree vigor of the young tree effect is not significant. We carried out in Jinxi orange erase part of the spring shoot Paul fruit test, achieved good results. Test results: Erase the total number of branches of the spring half of the best spring shoots, the fruit rate was 6.63%, 29.5% higher than the control; erase the number of branches of the spring shoots per plant rate of one third 5.61%, 9.6% higher than the control; all erasing spring shoot fruit rate was 6.41%, 25.2% higher than the control. Spring wiping also visible spring local conditions. Correct
