环割,就是用利刀或环割器切断果树主干或主枝基部皮层(至韧皮部,不伤木质部)一圈或几圈。环剥,就是将主干或主枝基部剥去一定宽度的皮层。果树实施环割、环剥技术,其原理是暂时阻碍光合作用生产的有机物向地下部运转,使营养集中在枝、芽上积累,促进花芽形成,提高花质,减少落花 Ring cutting, is to use a knife or torch cut off the main branch of the tree or the main branch of the base cortex (to the phloem, do not hurt the xylem) a lap or a few laps. Girdling, is the backbone of the main branch or stripped a certain width of the cortex. The implementation of the ring cut ring, girdling technology, the principle is to temporarily block the production of photosynthesis of organic matter to the underground operation, so that nutrients concentrated in the branches, bud accumulation, and promote flower bud formation, improve flower quality, reduce falling
