北疆准噶尔盆地冬季气候严寒,大中型栽培苹果品种,一般不能安全直立越冬,只能采用匍匐栽培,冬季埋土防寒越冬.这种方法违反了果树向上生长的自然规律,主干和主枝产生大量的徒长直立枝.这种直立枝处于优势地位,生长旺盛,难于结果,却大量夺取养分.若加剪除,不但边剪边生,且使树干裸露;听其生长,则影响日照、紊乱树形.在不断发生的直立枝影响下,其前面和下侧生长较弱,结果后易致早衰.我师十九团农场九队园林技术员侯秉乾同志,针对这种情况,在群众性的科研活动中创造了夏季摘心,抑制徒长,促进花芽形成,次年开花结果的办法,合理控制利用了直立枝和徒长枝. Winter in Junggar Basin in northern Xinjiang is extremely cold in winter and large and medium-sized cultivars of apple are generally unable to be erect overwintering in safety and can only be cultivated by creeping cultivation in winter, which is in violation of the natural law of upward growth of fruit trees. Large quantities of stems and main branches are produced Of the upright branches. This upright branches in a dominant position, vigorous growth, difficult to fruition, but a large number of seized nutrients .If plus cut off, not only cut edge Health, and make the trunk bare; to listen to their growth, then affect the sunshine, chaos tree Under the influence of the continuous upright branches, the growth on the front and the underside is weak, and the result is likely to cause premature aging. Comrade Hou Binggan, a garden technician of nine teams in the nineteen regiments of our division, responded to this situation. In the mass scientific research activities Created in the summer topping, inhibition of leggy, to promote the formation of flower buds the following year flowering approach, the rational control of the use of upright branches and leggy branches.
