桃树矮化密植可明显地提高早期产量,而且管理方便,但桃树是极喜光果树,对光照十分敏感,所以密植必须矮化,而目前尚没有理想的桃矮化砧和矮化品种。为了解决这个矛盾,我们曾想通过整形修剪来解决密植中的光照问题。1986年我所实验果园定植了10亩雨花露(砧术为毛桃),株行距为2.4×4米,对试验树进行Y形整形及相应的修剪。试验表明,以此树形适当密植的桃树可获得较高的早期产量,但很快出现枝叶郁闭,结果部位迅速外
Dwarfing peach planting can significantly improve the early yield, but also easy to manage, but the peach is a very happy light tree, very sensitive to light, so close planting must dwarf, but there is no ideal peach an dwarf an dwarf and dwarf varieties. In order to solve this contradiction, we have tried to solve the problem of light in close planting by shaping and trimming. In 1986, I experimented with orchard planting 10 acres of rain (anvil for the peach), spacing of 2.4 × 4 m, the test tree Y-shaped and the corresponding trim. Experiments show that peach tree with appropriate tree planting density can get a higher early yield, but soon foliage canopy closed, the results of parts quickly
