摘　　要：对云研77-2、云研77-4的月度产胶动态进行逐步回归分析研究得出,云研77-2、云研77-4的产胶量受月平均气温、早上8时温度影响较大,而对照GT1的产胶量受月平均气温、月平均相对湿度的影响较大;提出2个新品种由于4、5月份降雨量少,干胶含量高,产胶潜力大,产量高,可适当深割,放宽割胶的控制标准;9、10月份晨温低,相对湿度小,降水量少,产胶量高,可适当浅割或适量刺激与减少刺激数。The dynamis of monthly latex production of the two rubber varieties Yunyan 77-2 and Yunyan 77-4 was studied by regression analysis. Both the control GT1 and the tested varieties （Yunyan 77-2 and Yunyan 77-4, which were bred and selected by Yunnan Institute of Tropical Crops） would be influenced greatly by monthly average temperature. Morning temperature at 8 did much affect on latex yield to Yunyan 77-2 and Yunyan 77-4 while monthly average relative humidity did the same to the control. Thus, the rubber tapping standard should be formulated based on various conditions. In dry month of April to May, should give a proper strong rubber tapping to the two varieties for high yield and content of dry rubber. And should give a surface tapping with less stimulation or without stimulation in the month of September to October because of the low morning temperature, relative humidity and rainfall.
