摘要
隐形三套枝的修剪是初次提出来的 ,它不是指冬剪后三套枝各占 1 /3,而是指剪后要使三套枝在生长季节里达到真正的协调平衡 .它考虑的因素多 ,始终处于动态之中 ,其应用范围广 ,灵活多变 ,留枝量相对大 ,枝的利用率也高 ,故对早期丰产 ,尤其对克服大小年有显著的调节作用 .
Pruning of the hidden three sets of branches is suggested by the author for the first time. It doesn′t mean decreasing three sets of branches by one third after winter pruning, but indicate that the three sets of branches must be coordinated in growing seasons. Many factors affect it and it has been changing all the time. It can be applied widely and is changeable. The branches are enough relatively and can be used highly. So it has obviously adjusting role to high yield in the beginning, especially in rich and poor years.
