摘　　要：[目的]研究不同品系天然橡胶的性能。[方法]观察7个品系天然橡胶的新鲜胶乳的生理参数,将其离心浓缩后比较各个地区品系浓缩胶乳的性能,并且对浓缩胶乳硫化胶膜的物理机械性能进行研究。[结果]试验表明,云研77-4的蔗糖含量最高,热研7-33-97的硫醇含量最高,湛试93-114的总固干含最高,RRIM600浓缩胶乳的挥发脂肪酸值最高,热垦525胶膜的物理机械性能最好。[结论]研究可为橡胶栽培种植和产品性能需求选育高产、优质、优良的橡胶品系提供参考。[Objective] To study properties of natural rubber of different strains.[Method] The physiological parameters of 7 strains of natural rubber fresh latex were observed.And then centrifuge enrichment to compare the performance of concentrated latex from each district and each lines,and made research on mechanical properties of vulcanized rubber latex concentrate.[Result] The results showed that the content of sucrose was the highest in strain Yunyan77-4,the content of thioalcohol was the highest in strain Reyan 7-33-97,the content of total dry solid containing was the highest in strain Zhanshi 93-114,the number of volatile fatty acid in concentrated latex was the highest in strain RRIM600,the strain Reken525 had the best physical and mechanical properties in these strains.[Conclusion] The study can provide reference for selecting high yield and high quality rubber strain.
