摘　　要：为生产高产、优质芸豆,以黑龙江省北部高寒条件下3个主栽中粒芸豆品种为材料,分析了种植密度对不同品种芸豆产量、产量构成因素、商品与营养品质等方面的影响。结果表明:高寒地区芸豆种植密度与经济产量呈抛物线关系,密度为15万株.hm-2时,龙270230、龙芸豆3号产量最高,分别为2 287.93,3 225.87kg.hm-2。龙271076在密度为20万株.hm-2产量最高,为2 677.00kg.hm-2。3个品种单位面积荚数随密度增加而逐渐增加,单株荚数、主茎分枝和百粒重随密度增加呈下降趋势;商品率与粒重极差随种植密度增加表现趋势载然相反。In order to produce high yield and good quality kidney bean,taking three medium grain kidney bean varieties in North Frigid Region of Heilongjiang province as material to analyze the effect of planting density of different varieties kidney bean to field production,yield formation factors,products and nutritional quality effect.The result indicated that the frigid region kidney bean planting density and economic yield was a parabola relation,when density was 150 000plant.hm2,Long270230and Long Kidney Bean had the highest yield for 2 287.93,3 225.87kg.hm^-2,Long271076had the highest yield for 2 677.00kg.hm^-2 when density was 200 000 plant.hm2.Three varieties unit area pod number gradually increased with density increased,pod number per plant,caulis branches,100-grain weight were declined with the density increased.Commodity rate,grain density and planting density were negatively correlated.
