Cropping system in rubber plantations:
The wide spacing between row (DR system), an intercropping pattern in the whole rubber production period which provides more land and space available for crop intercropping without significant effect on rubber production, can effectively solve the issues of current intercropping systems.
The gap between rows is wider, people can engage in various agricultural activities of long-term crop production and normalize agricultural production, and thus attract planters to invest in rubber plantation, to improve production levels and to promote the standardization and industrial development of rubber plantation.
