摘　　要：研究了不同种植密度对青刀豆物候期、主要植物学性状及产量的影响。研究结果表明,合理密植可显著增加青刀豆产量,本试验中,以株距30 cm、每穴留3株为青刀豆春季栽培最佳种植密度,青刀豆产量为800.1 kg/667 m2。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.
