一、问题提出环状剥皮(以下简称环剥)对尚未开始结果的幼树可以促进早结果,对已开始结果的树可以提高早期产量。我们在西宁地区于1971年-1973年曾对吉光、元帅、祝光等三个品种进行过实验。结果证明,吉光品种经过环剥后,花芽占全枝发芽点的66.6％(而未环剥的仅占9.1％);元帅品种经过环剥后,花芽占全枝发芽点的60％(而末环剥的没有一个花芽)。
First, the problem raised ring stripping (hereinafter referred to as girdling) for young trees that have not yet started the results can promote early results, the results of the tree has been able to improve the early yield. We in Xining area in 1971 - 1973 had Ji light, Marshal, Zhu Guang and other three varieties of experiments. The results showed that flower buds accounted for 66.6% of germination points (without ring pecking only accounted for 9.1%) after ring-peeling, and flower buds accounted for 60% of germination points Girdling without a flower bud).
