果树的生长发育与周围环境条件是统一的。密植条件下的树体,同稀植树一样,受气候、土壤和管理条件的影响,因子比较复杂。本文就密植条件下的树体调节问题进行讨论。密度的问题,固然是密植的中心环节,密植园所出现的缺光、作业不便及果品质量差等问题,均与密度过大有关,同时,也与树体的有效控制能力有关。在一定密度下,将树体控制到相应大小,是密植成功的关键措施。 Fruit tree growth and development and the surrounding environmental conditions are unified. Trees under close planting conditions, like sparsely planted trees, are more complex due to climate, soil and management conditions. This article discusses the regulation of trees in close planting conditions. The problem of density is not only the key part of dense planting but also the problem of lack of light, inconvenience of operation and poor fruit quality in dense plantation. All of these problems are related to the excessive density and the effective control of the tree. Under a certain density, controlling the tree to the corresponding size is the key measure for success of close planting.
