1.疏 疏除冠内轮生、并生、徒长、重叠、密挤、病虫、干枯枝,以打开冠层,使其透光通风,为留下的枝条创造良好的生长条件。 2.缩 即对多年生枝先端下垂部分回缩到壮股、壮芽处,抬高枝条角度,增强生长势。剪口下若有二次枝可剪除,促其萌发新枣头。对过度衰弱的各级骨干枝应适度回缩,促进潜伏芽发出新枝,重新培养出主枝延长枝和侧枝,充实内膛。当骨干枝上出现更新枝时,可直接回缩至更新枝处。
1. Sparse sparse canopy, and students, leggy, overlapping, dense crowded, pests, dry branches, in order to open the canopy, so that its light and ventilation, leaving the branches to create good growth conditions. 2. Shrinkage of perennial branches drooping part of the contraction back to the Zhuanggu, strong sprouts, raise branches angle, enhance the growth potential. If the second cut under the mouth can be cut off, prompting the germination of new dates head. Excessive weakness at all levels of the backbone should be moderately retracted to promote the latent buds to issue new branches, re-cultivate the main branch to extend the branches and collateral, enrich the bore. When the sticks appear on the new branch, it can be directly retracted to the new branch.
