摘　　要：为研究不同的种植密度对扁豆产量的影响,寻求最佳种植密度来提高扁豆产量,以‘上海交大红扁豆1号’为供试品种,采用4种种植密度处理,通过对扁豆2个采收阶段的产量测定与分析,研究不同种植密度下的增产效果,为扁豆密植栽培提供理论依据。结果表明,密度低于49995株/hm2时,扁豆产量随着扁豆种植密度的提高而增加。超过此密度后,产量开始降低。此试验中,获得最高产量的种植方式是行距2m,株距0.2m,种植密度49995株/hm2,与传统种植密度相比,增产了124.3%。密植后,扁豆在采收第1阶段(4月1日至6月30日)增产80.48%～272.96%,采收第2阶段(7月1日至10月15日)增产0～9.8%,扁豆增产效果第1阶段大于第2阶段。在扁豆的生产中,通过动态的合理密植,可以明显提高扁豆的产量。The cuhivar, which was named ＇Shanghai Jiaoda Red Lentil No.1 ＇, was carried out to investigate the yield of Lablab purpurues under different planting densities. A appropriate planting pattern for increasing the Lablab purpurues production was found through evaluating and analyzing their yield under four different planting densities in 2 picking stages, which also provided a theoretical basis for its high density cultivation. The results indicated that the yield was increased with the planting density under 49995 plants/hm2, and began to decrease over this point. In the experiment, the best planting pattern was as follows： row distance and its plant distance was 2 m and 0.2 m respectively, and planting density was 49995 plants/hm2, which could increase 124.3% production compared with traditional cultivation pattern. The yield increase rate reached 80.48%-272.96% under high density cultivation at the first stage （April 15^th to June 30^th）, and it was 0-9.8% at the second stage （July 1^st to October 15^th）, which demonstrated that the effect on the first stage was greater than that of the second stage. The yield can be greatly improved through reasonable high density cultivation in the production of lentil.
