传统的果树栽培中土壤管理措施是清耕。要求在每年初冬树落叶后,深刨一次树盘,到吞车树发芽前也要刨。在果树年生长过程中,要多次锄树盘,保持无杂草。实践证明.冬、春刨树盘更新浅层根系,固然可以起到帮助树势转旺的作用,但是,深刨树盘,把20厘米表层土壤内的根系,全部破坏,使生长最活跃,对温差最敏感,吸收养分与合成细胞分裂素能力最强的浅层根系,不能很好地发挥作用,以至花芽难形成,果实糖度低、色泽差。日本果树专家农塚原一幸指出,苹果 Traditional soil management practices in fruit tree cultivation are tillage. Requirements in the early winter every year after deciduous trees, deep-planing a tree plate, to swallowing tree before budding also planing. In the process of annual growth of fruit trees, we should hoe many times to keep the weeds. Practice has proved that winter and spring planing tree roots to update the shallow root system, of course, can help to help the tree vigor, but the deep planing tree plate, the 20 cm topsoil within the soil, all destroyed, so that the most active growth, The most sensitive to the temperature difference, absorb nutrients and synthetic cytokinin the strongest shallow root system can not function well, as flower bud is difficult to form, low sugar content, poor color.
