在冬天,危害梨树的各种害虫的卵,蛹或幼虫,成长及各种病菌孢子大都隐藏在梨树的粗皮裂缝里休眠。因此,抓住这一有利时机,因树制宜地对梨树施以“刮皮术”,不仅可以促进老树更新生长,更重要的是能有效地消灭在梨树皮缝里越冬的大量病菌和害虫,为来年果树生长除病消灾,有利于梨树高产丰收。由于这一经验长期被果树应用于生产实践,并取得了明显的效果,所以,冬括皮、多结梨的经验,值得一提。
In winter, the eggs, pupae or larvae of various insect pests that endanger the pear tree grow, and the spores of various bacteria are mostly hidden in the rough skin cracks of the pear tree. Therefore, grasping this favorable opportunity, we should not only promote the regeneration and growth of old trees, but more importantly, effectively eliminate the large quantities of winter wintering in pear barks Germs and pests for the next year the growth of fruit trees in addition to eliminating diseases, is conducive to high yield pear harvest. As this experience has long been applied to fruit production practice, and achieved significant results, so the experience of winter brawn, multi-junction pear, it is worth mentioning.
