摘要
选取西双版纳地区4种常见天然橡胶品系RRIM600、GT1、云研77-4和PR107,研究各品系橡胶在不同割胶月份的凝胶含量及凝胶含量与橡胶性能的关系。结果表明:各品系天然橡胶的凝胶含量均有明显的季节性变化,凝胶含量大小RRIM600>PR107>云研77-4>GT1;单一品系橡胶的P0、门尼黏度及拉伸强度与凝胶含量都有明显的正相关规律;不同品系间橡胶凝胶含量与性能之间没有可比性。
Experiment of four Hevea clones(RRIM600,GT1,Yunyan774 and PR107)wildly planted in Xishuangbanna was carried out to study the effect of tapping time on gel content of natural rubber and relationship between gel content and properties of natural rubber.The results showed that there was obvious seasonal change in gel content for different clones.RRIM600 has the highest gel content followed by clone PR107 and Yunyan774,and GT1 the least.There is a positive correlation among gel content and P0 of natural rubber,as well as Mooney viscosity in a certain clone,and there is incompatible between gel content and properties of natural rubber from different clones.
