在日本,对温州蜜柑实行计划密植栽培近20年。现在新栽的果园,虽然其密度不一,但多采用计划密植法,因其优点是可增加幼龄期间的产量,显著缩短无收益期。然而,不管是平坦的水田轮作园或山地果园,凡在土壤保水性强而肥沃的地方,往往树势过强、着花不良,不能充分获得收益,并且树与树之间容易交叉混合,表现出过密的害处。这样,尽管特意进行计划密植,却不能缩短无收益期。 In Japan, the planting of Wenzhou Satsuma planting plan nearly 20 years. Now the newly planted orchards, although they are of different densities, adopt more dense planting plans because of their advantages of increasing yield during their young age and significantly shortening the period of no gain. However, whether it is a flat paddy field orchards or mountain orchards, where soil water retention is strong and fertile, it tends to be overgrown and poorly populated, not fully rewarded, and trees and trees are easily cross-mixed Out of the secret of harm. In this way, although deliberately plan intensive, but can not shorten the non-profit period.
