此次果树冻害严重，据调查，香蕉、龙眼、荔枝、柑桔等果树均受不同程度的冻害。果树受冻后，地上部器官（叶、枝梢）遭到破坏，使根系、枝干的生理活动减弱，地上部与地下部失调。同时，由于落叶枝条外露，抗性也大大减弱，所以冻害后的护树保树工作应抓紧。不同果树品种冻害? The fruit tree frost damage, according to the survey, bananas, longan, litchi, citrus and other fruit trees are subject to varying degrees of frost damage. After the fruit trees are frozen, the organs above the ground (leaves and shoots) are destroyed, which weakens the physiological activities of the roots and branches, and the aboveground and underground parts are out of tune. At the same time, due to the exposed branches and declines, the resistance is greatly weakened, so the protection of trees after freezing damage should be paid close attention.
