核桃在修剪期内有“伤流”特性,即从秋季落叶到次年发芽展叶期间,若造成枝干伤口,大量营养液就会从伤口流出,影响树体的生长发育坐果。因此,结果树果实采收后至叶片变黄以前(9月上旬-10上旬)带叶修剪最好。修剪主要是安排合理的树体骨架,枝条分布均匀合理,通风透光,达到树壮果丰的目
During the pruning period, walnuts have the characteristic of “bleeding”, that is, during the period from the fall leaves to the germinating leaves during the following year, if a large number of wounds are caused, a large amount of nutrient solution will flow out from the wound and affect the growth and development of the tree. As a result, it is best to have leaf pruning until the leaves turn yellow (early September-early 10) after harvest of the tree fruits. Pruning is mainly to arrange a reasonable tree skeleton, branches and distributed evenly and reasonably, ventilated and translucent, to reach the tree fruiting abundance of the head
