Abstract
[Objective] The study aimed to confirm the optimum planting density of Yingge mung bean in Taihang mountain area.[Method] Four planting densities of 6.0×104、9.0×104、1.2×105 and 1.5×105 plants/hm2 were set up and the influence of planting density on the growth of Yingge mung bean in Taihang mountain area was studied through investigating the plant height,pod number per plant,branch number on the main stem,grain number per pod and yield.[Result] The plant height and pod number per plant of Yingge mung bean in Taihang mountain area increased along with the increment of planting density and reached the maximum value when the density was 1.5×105 plants/hm2.The maximum values of branch number on the main stem and grain number per pod appeared when the planting densities were 9.0×104 and 1.2×105 plants/hm2 resp.At the beginning,the yield increased along with the increment of planting density,the highest yield was 1 255.6 kg/hm2 when the density was 1.2×105 plants/hm2,and then the yield started to decrease.[Conclusion] The optimum planting density of Yingge mung bean in Taihang mountain area was 1.2～1.5×105 plants/hm2.
