摘要
本文探讨了尤溪县黑荆树冻害与立地因子及气象因子间的关系,指出低温和持续霜冻是造成黑荆树冻害的主导因子,造林地的坡形、坡度和坡向对黑荆树冻害影响大。应注重宜林地的选择及栽培措施的改进,抗寒品种是关键。
In this paper, the relationships between Acacia mearnsü's freeze injury and site factors, meteorological factors have leen studied. The analyses showed that low temperature and continued frostday were leading factor of A. mearnsü's freeze injurg, and that slope shape, gradient and slope direction of planting sites were also inportance factors. As mentioned above, We must lag stress on selection of planting sites and improvement of cultural measures, especially Selection of frost-resistant varietg of A. mearnsü.
