果树为多年生植物,土壤状况直接决定着果树的寿命与产量。果树管理多为人工操作,人来人往易使果园土壤板结,造成树势衰弱、产量减低、病虫害严重。因而,要想高产稳产必须深翻果园。 深翻果园一般每年进行两次,第一次在5月中、下旬,第二次应在9月上旬。若果树株行距小,特别是北疆匍匐果树树冠离地面 Fruit tree is a perennial, soil conditions directly determine the life and yield of fruit trees. Fruit tree management and more for manual operation, coming and going easy to make orchard soil compaction, resulting in frailty, yield reduction, pest and disease serious. Therefore, in order to high and stable yield must deep turn the orchard. Deep turnip orchard generally twice a year, the first time in mid-May, late, the second should be in early September. If the tree spacing is small, especially the northern crown of prostrate fruit trees from the ground
