摘　　要：为明确内蒙古东部干旱半干旱地区绿豆种植的适宜播期及密度,以半蔓生型和直立型绿豆品种为试验材料,研究不同播期、密度绿豆群体生长及产量性状的变化。结果表明,随着播期的推迟绿豆群体叶面积指数、株高、单荚粒数大体逐渐下降,单株分枝数、单株荚数、单位面积子粒产量大体先升后降。绿豆种植的适宜播期在5月下旬-6月上旬,半蔓生型品种在种植密度为23万株/hm^2时产量最高,若晚播应加大种植密度到27~30万株/hm^2;直立型品种适宜高密度种植,不适宜晚播,适宜种植密度为27~30万株/hm^2。To investigate the suitable sowing time and density of mung bean in arid and semiarid regions of Inner Mongolia. Semi-erect and erect mung bean cultivars were used as test materials to study the changes of mung bean population growth and yield traits under different sowing time and density. The results showed that with the delay of sowing time, mung beans group leaf area index, plant height, grains per pod decreased but the number of branches per plant, pods per plant and yield increased first and then decreased. The suitable sowing time of mung bean was between late May and early June. The semi-erect cultivars had the highest yield with planting density 230 000 plants/hm^2, increase planting density to 270 000-300 000 plants/hm^2 was need for late sowing. Erect cultivars was suitable for high density planting, but not suitable for late sowing, the suitable planting density was 270 000-300 000 plants/hm^2.
