黑龙江省冬季系全国最寒冷的地区,开春昼夜温差大,白天树木吸收热量增高,夜间温度急剧降低,冷热温差大,易使树木得腐烂病,轻则导致树木畸形生长,重则造成树木死亡。树木涂白即涂混合石灰水,用生石灰、油类、农药等调制而成(因树类不同,配方比例各异)。涂自有四点好处。 一、防冻害,提高成活率。白色物体能反射阳光,树干涂白后不直接吸收阳光,缩小了昼夜温差,有效地控制了因冻害而引起的腐烂病,提高了成活率。
Winter in Heilongjiang Province is the coldest area in the country. The temperature difference between day and night in spring is big, the heat absorbed by trees increases during the daytime, the temperature drops sharply at night, the temperature difference between hot and cold is big, the tree is easy to degenerate, which leads to the deformity of trees and the death of trees. . Trees coated with white coated lime water, with lime, oil, pesticides and other modulation (due to different tree types, the proportion of different formulations). Tu own four benefits. First, frost damage, improve survival rate. White objects can reflect the sun, the tree trunk does not directly absorb the sun after the white coating, reducing the temperature difference between day and night, effectively control the rot caused due to frost damage and improve the survival rate.
