Because the temperature is higher before the low temperature comes, the dormancy of the fruit tree is shallow, and the ability to resist cold is poor. When the temperature suddenly drops, the tree can't adapt. High temperatures during the day, low temperatures at night, excessive temperature differences between day and night, and frequent frost damage are the same reason. The trunks are white in winter, and they reflect sunlight in sunny days, reduce solar heat absorbed in sunny days, reduce the temperature difference before and after frost damage, and the temperature difference between day and night on trunks, which can prevent or reduce freezing damage.崭獭 崭獭 崭獭 (8) 鸪取(四) 投嗟 嗟 苑 蓝 澄 澄 澄 澄 澄 澄 澄 澄 澄 澄 澄 澄 澄 澄 澄 康 康 康 康 康 康 康 康 康 康 康 康 康 康 康 康 康 康 康 康 堪 堪 堪 堪 堪 堪 堪 堪 堪 堪 堪 堪 堪 堪 堪 堪 堪 河 河 河 河 河 河 河 0 kg, sulfur powder 1 kg, salt 0.2 kg, add water 40 kg was evenly mixed into a paste and the trunk was brushed white from late November to late December.
