计划密植,又称“变化密植”,不同于一次性定植。为了获得早期丰产和长期丰产,以提高经济效益,在开始栽植果树时,就要分出“永久株”（从建园开始到全园更新永久保留的植株）和“临时株”（根据空间和地面情况逐步去掉的植株）,两者同时定植,以弥补前期永久株树体小、枝量少、叶面积覆盖率低之不足,增加叶面积系数,尽快使枝叶满冠、树满园,以利于充分利用太阳光能,形成更多的有机物质,发挥群体结果 Plan dense planting, also known as “change close planting”, is different from the one-time planting. In order to obtain early high yield and long-term high yield, in order to improve economic efficiency, when planting fruit trees, it is necessary to separate “permanent” plants (plants permanently preserved from the establishment of the park to the whole park) and “temporary plants” (according to space and Ground conditions gradually removed plants), both at the same time planting to make up for the early permanent tree small body, less branches, leaf area coverage is low enough to increase the leaf area coefficient, as soon as possible to make full of branches and leaves, tree garden, with Benefit to make full use of solar energy, the formation of more organic matter, to play a group result
