众所周知,巴西橡胶树（Hevea brasiliensis）,从南纬6°左右的巴西他帕卓斯河（Tapajos River）附近的巴颜姆（Boim）热带原产地东迁北移到南亚热带地区的我国华南植胶区,因纬度偏北,某些年份冬期气温偏低,给橡胶生产造成不同程度的损失,解决橡胶树寒害问题虽有多种手段,诸如环境地形的选择与改造,防寒、避寒等栽培措施。但实践证明,选育抗寒高产品系对于减少寒害,建立高产稳产胶园,不断北移——扩大植胶面积,增加产量,满足我国四个现代化建设需要是一项经济而有效、积极而重要的途径。
It is well-known that Hevea brasiliensis migrates from the east of the Boim tropical origin near the Tapajos River in Brazil at about 6 ° South latitude to the south China sealant in the southern subtropics Due to the latitude northerly, the temperature in some years is relatively low in winter, causing different losses to rubber production. There are many measures to solve the problem of chilling injury of rubber trees, such as the selection and transformation of environmental topography, measures to prevent cold and avoid cold. However, it has been proved that selecting high-yielding cold-resistant products is an economical and effective way to reduce the cold damage, establish a high-yielding and rubber-producing industrial park, and move northward - expanding the planting area, increasing the output and meeting the needs of the four modernizations in our country Important way.
