Abstract: This paper analyzes the changes in rubber tree planting density,number of growing trees per ha,number of trees available for tapping,percentage of effective tapping trees,and types of available trees in the rubber plantation based on the recent data collected from the rubber tree production in China.It also analyzes the effect of available tapping trees per unit area on the land output capacity in the rubber plantation and its reasons,and makes some suggestions on how to improve the number of available trees under tapping in rubber plantations.
