| 摘 要： | 研究了在天然鲜胶乳中分别以盐酸羟胺、硫酸羟胺、盐酸联胺、硫酸联胺、水合联胺、盐酸氨基脲、苯胺等作恒粘剂，采用微生物凝固工艺制备的天然橡胶(NR)在常温贮存过程中门尼粘度的变化。结果表明，盐酸羟胺、硫酸羟胺的用量在0.05%(对干胶)时就可以使NR的门尼粘度稳定，可制得低粘度的恒粘NR；水合联胺的用量需要达到0.20%～0.30% 时，可制得中高粘度的恒粘NR；盐酸氨基脲的用量在0.05% 时，可制得中等粘度的恒粘NR，用量在0.10%～0.20% 时，可制得低粘度的恒粘NR；苯胺的用量在0.01%～0.03% 时，可制得中等粘度的恒粘NR，用量在0.05%～0.20% 时，可制得高粘度的恒粘NR；硫酸联胺和盐酸联胺无法使NR 的门尼粘度稳定，但它们能使NR的门尼粘度增加。

| Abstract: | The tropical invasion weed Eichhornia crassipes was used as the donor plant to determine the influence of its aqueous extracts on the seed germination and the seedling growth of four kinds of common plants which grow in the tropical areas, and explore the biological activity of Eichhornia crassipes on other plants. The test result indicated that in supply concentrations, the aqueous extracts from Eichhornia crassipes inhibited the seed germination of Raphanus sativus, Brassica pekinensis and Amaranthus mangostanus L., and the effect increased with concentrations. However, the aqueous extracts obviously promoted seedlings' growth of the three receptor plants, and the effect increased with concentrations, but exceeding certain concentration, the promotion effect starts to reduce. |
