早春的“倒春寒”气候是红松发生“红梢”现象的主导因素,不同林地“红梢”发生率不同,是由于该林地苗木接收的太阳辐射不同,引起气温变幅大小不同而造成的。一切能减小气温变幅,使气温缓慢回升的措施,都能降低“红梢”的发生率。 In early spring, the climate of “late spring cold” is the dominant factor in the occurrence of “red shoots” of Korean pine. The different occurrence rates of “red shoots” in different forestlands are due to the different solar radiation received by seedlings in this woodland, Caused by different sizes. Everything that can reduce the temperature amplitude, so that the temperature rise slowly measures, can reduce the “red tip” the incidence.
