1983—1984年研究了红玉血橙(Citrus sinensis Osbeck)、兴津和尾张温州(C.unshiu Tanaka)在雅安生态条件下抹芽放梢和修剪效应的研究。研究结果表明,三个供试品种抹除夏梢,放春、秋两次梢,对于减少初投产树的落果,提高早期产量有显著作用。八月上旬为放梢适期,八月梢为最佳梢类。秋梢结果母枝可以进行人工摘心,九、十月摘心对第二年结果影响不大。秋梢母枝二、三月摘心或较重程度短截,能减少花量,促发春梢营养枝。为柑桔密植、早结丰产提供依据。 In 1983-1984, research on the shoot-budding and pruning effects of Citrus sinensis Osbeck, Xingjin and C.unshiu Tanaka under the Ya’an ecological conditions were studied. The results showed that the three test varieties to erase summer shoots, let spring and autumn two shoots, to reduce the first castration tree drop fruit, improve the early yield has a significant role. In early August for the shoot shoot period, August shoot for the best shoot class. Autumn shoots results can be artificially capitated branches, in September and October topping the second year results have little effect. Autumn shoot mother twins in March or topping or heavier short cut, can reduce the amount of flowers, promote spring shoots nutrition branch. Citrus dense planting, early termination of high yield basis.
