经验证明:柑桔树在冻害后一般不能及时显出冻害的范围,因此不要匆忙进行修剪,否则要返工。嫩枝及叶丛可在几天后显出冻害程度,但老枝条在冻害后几星期,甚至更长时间才显出来,严重冻害的树在几个月也难测出冻害的最大程度。对冻害树应该有充分时间让新梢萌发出来,不再发生枯枝时才进行处理,晚期进行修剪反使果树恢复加快。受冻害树的果实应尽快摘掉。对冻害树主干及主枝的处理可根据五种受害程度,分别
Experience has shown that: citrus trees generally can not show the scope of frost damage after frost damage, so do not rush to pruning, or to rework. Twigs and foliage can show the degree of frost damage in a few days, but the old branches show up in weeks or even longer after frostbite, and the trees with severe frost damage can hardly detect the frost damage in a few months. Frost damage to the tree should have sufficient time to sprout out of shoots, no longer occur when dead branches, pruning in the late anti-fruit trees to speed up recovery. Frozen trees should be removed as soon as possible. Frost damage to the tree trunk and the main branch of the treatment according to the five kinds of victims, respectively
