本文研究了四川省引种栽培的辐射松的抗逆性。研究结果表明:辐射松幼林在四川岷江上游干旱河谷表现出较强的抗旱性和较强的抗病、抗虫能力;根据造林地海拔与林木受冻害的关系,提出在岷江上游河谷区适宜栽培的海拔上限为2100m。辐射松在气温较高、湿度较大的区域造林保存率极低,而且易感病虫害,不宜引种栽培。
The paper studied the resistance of introduced radix pine in Sichuan province. The results showed that: young pine stands in the upper reaches of the Minjiang River in Sichuan dry valley showed strong drought resistance and strong resistance, insect resistance ability; according to the relationship between the altitude of the forestation and the forest by the frost damage, proposed in the upper reaches of the Minjiang River valley suitable for cultivation The elevation of 2100m. Pinus radiata pine in the high temperature and humidity of the region afforestation preservation rate is extremely low, but also susceptible to pests and diseases, should not be introduced cultivation.
