整形修剪的目的是造成一定的树形,争取树冠结果面积的立体化,调节生长发育以及抽梢与开花结果的矛盾,充分发挥结果能力,平衡大小年,提高抗逆力,改进品质,降低生产成本。一、整形修剪的基本概念修剪包括整形和剪枝。柑桔树体处在幼龄阶段时,就应考虑将其修剪成什么形状,所以整形是修剪的第一步。待树形构成后,在较长年限内保持良好的树形,年年丰产稳产,品质优良,须疏删或短截树冠内的枝梢,或用其它方法调节其生长,使枝条新旧交替、生长得度,年年结果不绝,直至整个树体衰老,无法挽救为止。前期对幼年树整形修剪可
The purpose of plastic pruning is to create a certain tree shape for three-dimensional crown area of the results to adjust the growth and development as well as the culvert and flowering contradictions, give full play to the results of ability to balance the size of the year, improve resilience, improve quality and reduce production cost. First, the basic concept of plastic trim pruning, including plastic and pruning. When the citrus tree is young, it should be considered what shape it is trimmed so shaping is the first step in pruning. After the tree structure is formed, it maintains a good tree shape over a long period of years, and the annual yield is high and stable with good quality. The branch tips in the crown of the tree shall be sparsely or shortened or adjusted by other methods to alternate the old and new branches. Growth rate, the annual results never go, until the entire tree aging, irreparable so far. Pre-plastic tree juvenile pruning can be
