结合秋季土壤深翻对幼旺树进行断根,可减弱根系生长势,提高树体营养积累水平,使较多营养供给花芽分化和开花座果。断根方法,在施基肥时,沿树冠投影外围挖40～50cm 深的环沟,沟宽3～4cm,切断直径小于2cm 的水平根,然后将基肥的土混合均匀填平,并灌足水。地上部分,修剪时除主侧枝延长枝打头外,一
In combination with deep soil fall in autumn, the pruning of the young tree can weaken the growth potential of the root system, increase the level of nutrient accumulation in the tree, and make more nutrients for flower bud differentiation and flowering. When the base fertilizer is cut off, a ring groove with a depth of 40-50cm is dug along the periphery of the canopy crown. The groove width is 3 to 4cm, and the horizontal roots with a diameter of less than 2cm are cut off, and then the soil of the base fertilizer is evenly filled and filled with enough water. On the ground, in addition to the pruning of the main branches to extend the branches pruning, one
