Abstract

The growths were comparatively analyzed for rubber tree variety ‘Yunyan 77-2’ at difference slope aspects (shady and sunny slope) in the experimental base of environment-friendly rubber plantation of Yunnan Institute of Tropical Crops. The results showed the survival rate of rubber trees was 98.67% on sunny slope, higher than that on shady slope. The average circumference of stem was 29.52 cm on sunny slope, significantly higher than that on shady slope by the end of 2018. In the first three years, the annual average growth of stem circumference was significantly higher on sunny slope than that on shady slope, but no significant difference in the fourth year. In general, ‘Yunyan 77-2’ grew better on sunny slope than that on shady slope.
