环割是利用机械作用促使楷杷结果树增加产量的一种技术措施,通过机械作用刺激枇杷结果树雌性激素分化,促进花芽分化的人为机械作用,为花粉形成创造条件。笔者连续3年在枇杷结果树上,采用了这一技术。一、环割对象;枇杷结果树多以夏梢形成结果枝,春秋梢极少有形成结果枝的,而营养生长过旺的树,夏梢转化为结果枝的也不多,春秋梢更是少见。特别是初进人结果期的生长势极强的树。不施行环割技术亦很难结果。因此,环割施用对象以这些结果树为主。二、环割时间:枇杷结果树的花芽分化时间,一般在7月中旬至8月中旬,这期间我县雨量充沛,阴天较多,是枇杷结果树营养生长的极盛期,很容易形成 Ring cutting is the use of mechanical action to promote the yield of the fruit of a method to increase the yield of loquat fruit tree by stimulating the mechanism of estrogen differentiation and promote flower bud differentiation of human mechanical action to create the conditions for pollen formation. The author for 3 consecutive years in the loquat tree results, using this technology. First, the ring cutting object; loquat results mostly to the summer tip of the formation of branches, the spring and autumn shoots rarely results in branches, and vegetative growth over the tree, the summer shoots into the results of the branches are not many, Rare. In particular, the results of the early entrants growing strong potential of the tree. Not circumcision technology is also difficult to result. Therefore, the target of ring cutting is based on these result trees. Second, the ring cutting time: loquat tree flower bud differentiation time, usually in mid-July to mid-August, during this period abundant rainfall in our county, more cloudy days, is the eutrophic fruit tree growth of the peak, it is easy to form
