山楂果实个小,结果部位高而分散,因此人工采收山楂较费工。目前,生产中采收山楂多用棍打、摇树、手工摘的方法,这不仅效率低,而且果实易受伤,树体枝芽也易被打坏。为了解决上述问题,我们试用喷乙烯利催落的方法采收山楂,收到较好效果。 在山楂果实成熟前一周(辽北地区为9月末～10月初),用配好的500～600ppm乙烯利药液向树冠喷洒。喷药后6～7天,将棚布铺在树下,然后轻晃枝干,果实即自行脱落。 在试验中发现,喷乙烯利催落山楂,在气候干旱、气温高、小气候暖和以及树势较弱的情况下,催落效果明显。
Hawthorn fruit is small, the results of high and scattered parts, so artificial hawthorn harvest more effort. At present, the production of hawthorn and more use of sticks, shake the tree, hand-picked method, which is not only inefficient, but also vulnerable to the fruit, tree buds are also vulnerable to damage. In order to solve the above problems, we try to spray ethephon reminder hawthorn harvest method, received good results. In the week before the hawthorn fruit ripened (northern part of Liaoning from the end of September to the beginning of October), it was sprayed on the canopy with 500 ~ 600ppm ethephon liquid. After spraying 6 to 7 days, the shop shed shop under the tree, and then light branches, the fruit that fall off on their own. In the experiment found that spray ethephon hawthorn off, in arid climate, high temperatures, warm microclimates and the situation is weak, the effect of catcher is obvious.
