柑橘1.减少叶片蒸腾。柑橘树枝和叶片若较长时间处于零下温度,多数枝叶会发生不同程度的冻伤。如冻后突遇晴好天气,白天升温过快,细胞内和细胞间的冰晶迅速溶化,势必加重叶片组织的失水,加剧冻害程度。可对树冠进行覆盖,防止树体因升温过快加剧冻害; Citrus 1. Reduce the leaf transpiration. If the citrus branches and leaves for a long time at minus temperature, most branches will have different degrees of frostbite. Sudden contact with good weather, such as freezing weather, during the day warming too fast, rapid melting of intracellular and intercellular ice crystals, is bound to increase the loss of leaf tissue, exacerbating the degree of frost damage. Tree crown can be covered to prevent the trees due to excessive heating to aggravate the frost damage;
