本文根据在福建橡胶林场内进行的小气候观测值,拟定出辐射低温和平流低温的指标,结合调查七十四个三叶橡胶树林群体的受害情况,来分析不同品系的抗寒性,运用相关图表法求得受害临界低温值,应用比较表和四区座标法来探索各品系的抗平梳低温或抗辐射低温的特性。结果与多年寒害调查实践相吻合,看来这些方法是可行的。
Based on the microclimate observations in rubber plantations in Fujian Province, this paper developed indicators of low temperature radiation and advection and low temperature, combined with the investigation of the damage of seventy-four rubber tree communities to analyze the cold resistance of different strains, using the related charts France obtained the critical low temperature damage value, the use of comparison table and four districts coordinate method to explore the various strains of anti-combing low temperature or anti-radiation low temperature characteristics. The results are consistent with many years of cold damage survey practice, it seems that these methods are feasible.
