一、概况闽南垦区自1953年引种试种橡胶树以来,经过二十多年的艰苦努力,到现在已发展12.8万亩,年产干胶500多吨,积累了生产、科研等方面的经验.本垦区虽然纬度较高,橡胶树曾遭受过几次大寒潮袭击,给生产造成一定的损失,但是,只要合理的使用品系,认真地选择小环境,加强防寒和抗寒的栽培措施,就能减轻或避兔寒害的威胁.历次寒潮中,不同的品系抵御不同类型低温能力差异很大;而同一个品系在不同的小环境中的寒害差异也很明显.所有这些都直接影响到无性系的生长和产胶.我们通过对垦区的七个县十三个农场和公社的六十七个林段主要无性系适应性的调查,进一步了解其抗寒、生长及产胶水平,为生产上的合理配置品系提供依据.
I. Introduction Since the introduction of the test-rubber tree in Minnan Reclamation Area in 1953, after more than 20 years of arduous efforts, up to now, it has developed 128,000 mu with an annual output of more than 500 tons of rubber and has accumulated experience in production and scientific research. Although the latitude of the reclamation area is high, the rubber tree has suffered several large cold spells and caused some losses to the production. However, as long as the reasonable use of strains, serious selection of small environment, and strengthening cold and cold cultivation measures can reduce or In the cold, the ability of different strains to withstand different types of low temperature greatly varies, while the same strains in different small environments also have significant differences in chilling injury, all of which have a direct impact on clonal growth and Through the reclamation of 13 counties in seven counties and communes 67 forest climax to investigate the adaptability of the further understanding of its cold, growth and production level, for the production of a reasonable allocation Lines provide the basis.
