摘　　要：研究了生物凝固液用量、鲜胶乳浓度、气候条件、氨含量等因素对鲜胶乳生物凝固效果的影响。结果表明:凝固剂适宜用量为10%;鲜胶乳浓度对凝固影响较小;当全天最高气温在25℃以下时,胶乳完全凝固需16 h以上;氨含量达0.02%时即可显著影响胶乳的凝固,用量达到0.08%时,胶乳不能凝固;添加辅助凝固剂可加快胶乳的凝固。The effects of dosage of bio-coagulation liquid, concentration of natural rubber latex, climate condition and content of ammonia on the speed of bio-coagulation of fresh natural rubber latex were studied. The results showed that the suitable dosage of bio-coagulation liquid was 10% and the influence of content concentration of natural rubber latex on the speed of bio-coagulation was less. It needs more than 16h for natural rubber latex coagulation completely when the temperature was lower than 25 ℃, the content of ammonia had significant effect on bio-coagulation of fresh natural rubber latex and the latex can＇t coagulation when reached 0.8%and booster can increase the speed of bio-coagulation of fresh natural rubber latex.
