计划密植栽培是柑桔生产上推行的一项新技术。密植桔园随着树龄的增长和树冠的扩大,相继出现树冠郁闭、内膛空虚、结果部位外移等现象,影响了密植桔园的持续丰产和果实质量,成为当前生产中亟待解决的问题。为此,我们对密植郁闭园采取以大树移栽为主的试验示范,现总结如下。 Planned planting is a new technology introduced in the production of citrus. With the growth of the tree-planting age and the expansion of the canopy, the close-planting orchards have successively emerged such as canopy canopy, empty internal cavity and relocation of the result site, which have affected the continuous yield and fruit quality of the close-planting orange orchard and have become the problems to be solved urgently in the current production . To this end, we have to close the dense canopy Park to take the test of large-scale transplanting demonstration, are summarized as follows.
