摘要：

以铁丰29大豆为试材，研究了不同栽培密度对大豆生长、结荚特征及产量的影响。采用两种行距40，60cm，四种株距15，20，25，30 cm共8种栽培密度进行了大豆的田间栽培，调查了不同栽培密度条件下产量及相关指标。结果表明：60cm行距条件下大豆的株高、结荚高度明显高于40cm行距的处理；行距和株距对主茎节数的影响无明显的规律性，对有效分枝数、百粒重也无明显影响；株行距为40cm×30cm时，单株荚数、有效荚数、单株粒数、产量显著高于其它处理；大豆品种铁丰29最适宜栽培密度株行距为40cm×30cm，合理的栽培密度是夺取大豆高产的关键措施。

Abstract:

Soybean cultivar ‘Tiefeng-29’ was used as material to study the effects of planting density on growth， pod-bearing and yields. were 40，60cm， and plant spacing were 15，20，25 and 30 cm respectively. Yields and related indexes were investigated under different planting density in field culture conditions. The results showed that: plant and pod height were higher under 60cm row spacing conditions than those under 40cm row spacing conditions. Rules of row and plant spacing effects on number of node was not obvious. Numbers of branch and 100-grain weight was not affected by row and plant spacing. Pod number per plant， valid pod number and yield were significantly higher than other treatments under 40cm×30cm row and plant spacing condition. In conclusion， the proper planting density was 40cm×30cm for highest yields. Reasonable planting density was one of the key measures leading to high yields.
