拉枝是果园常规管理的一项基本技术措施。对幼树进行合理拉枝,不仅能调节树体结构、改变光照、缓和树势,而且能提早形成花芽,达到早果、早丰的目的。但在生产实践中应用拉枝技术时,存在一些不当之处,应引起注意。 1.拉枝时间不当。在果树生产中,果农习惯在冬剪时同时进行拉枝。这时拉枝,首先由于树液尚未流动,枝干脆硬,拉枝容易破裂,造成伤害;其次枝条背上部易萌发出许多旺枝,如果夏季修剪控制不当,会形成“树上长树”现象,扰乱树形,影响通风透光,不利花芽形成,达不到早果早丰的目的。大量实践表明,拉枝应在8月
Pulling branches is a basic technical measure of orchard’s routine management. Solely on the saplings, not only can adjust the structure of the tree, change the light, ease the tree vigor, but also the early formation of flower buds, to achieve early fruit, early Feng purpose. However, in the practice of production branches pull technology, there are some inadequacies, should be noted. 1 pull the wrong time. In the production of fruit trees, fruit farmers accustomed to pulling branches in winter shear. At this time pull the branches, first of all because the liquid has not flowed, branches crisp hard, pull the branch is easy to rupture, resulting in injury; followed by branches back to the Ministry of easy to sprout many wangzhi, if the summer pruning improper control, will form "Phenomenon, disrupt the tree shape, affect the ventilation and light, unfavorable flower bud formation, fail to achieve the purpose of early harvest early fruit abundance. A lot of practice shows that the pull should be in August
