We studied the effects of different planting densities on the phenological phase, main botanical characters and yield of green bean cultivar Yonglv No.4. The results showed that, rational close planting were contributive to increase the yield of green bean significantly, and the optimal plant density was 30 cm in row spacing and three plants in a hole for spring cultivated green bean in our research, under the condition, the yield of green bean was 800.1 kg/667 m2.
