为了比较机械的和化学的方法在促进“元帅”幼树的花芽分化及座果率方面的效果,进行了三年的试验。环剥、开张主枝角度和生长调节物质,对于削弱顶端生长都达到予期效果,但是这些处理都没有稳定地增加开花量。当开花量提高时,座果率不一定高.环剥能最稳定地提高开花量。1000pp m 的乙
In order to compare the mechanical and chemical methods in promoting “marshal” sapling flower bud differentiation and fruit set rate, conducted a three-year trial. Girdling, opening of main branch angle and growth regulators, all achieved the expected effect of weakening the apical growth, but none of these treatments steadily increased flowering. When the flowering increased, the fruit rate is not necessarily high. 1000pp m of B.
