矮化密植能使柑桔有效地提早丰产,又便于果园管理和实现果园机械化,是当前世界果树生产的主要趋向。柑桔密植有利于树冠的防寒,在柑桔冻害威胁较大的地区,更有其特殊的实用意义。 早在1963年春,我们就结合抗寒栽培开展了密植试验。试验以温州蜜桔为试材(主要品系是尾张), Dwarf and dense planting can make citrus effectively yield early, facilitate orchard management and realize orchard mechanization, which is the main tendency of the world’s fruit production. Citrus close planting is conducive to the canopy of cold, orange citrus in the larger threat to the area, more of its special practical significance. As early as the spring of 1963, we conducted intensive planting experiments in combination with cold-resistant cultivation. Wenzhou orange test as a test material (the main strain is the tail Zhang)
