目前,桃园因修剪、采收以及夏季的过旺生长,致使桃园投资很高,所以不得不考虑改变传统的修剪与管理方法。现在正研究密植的篱芭型桃园采用采收后进行剪顶的方法,以限制树的体积,提高亩产量来降低桃园的管理投资。在美国东南部,由于采用了这种方法,幼龄树和成年树都获得了较高的产量。 At present, Taoyuan has had to invest heavily in pruning, harvesting and over-growth in the summer, so it has to consider changing the traditional methods of pruning and management. We are now studying the method of shearing the harvested fence type of Taoyuan after harvesting to limit the size of the tree and improve the yield per acre to reduce the management investment in Taoyuan. In the southeastern United States, both young and adult trees achieved higher yields due to this method.
