摘　　要：为探索不同施肥量和不同栽培密度的组合对大豆农艺性状和产量的影响,以期提升大豆栽培生产效率,在保护生态环境的同时获得较高的大豆产量。本文以鲜食秋大豆品种萧农秋艳为试验材料,考察不同栽培密度(10,15,20万株·hm^(-2))和氮肥施用量(75,112.5,150kg·hm^(-2))组合对大豆光合性能,农艺性状和产量的影响。结果表明:在栽培密度为15万株·hm^(-2),氮肥施用量为112.5kg·hm^(-2)处理下,萧农秋艳大豆产量较高,农艺性状较好,光合性能较强。较常规氮肥施用量减少25%,配合适当增加栽培密度的措施,萧农秋艳大豆产量较高,植株光合效率较高,农艺性状优良,且对生态环境友好。To explore the influence of different fertilizer application amount and cultivation desity combinations on agronomic traits and yield,in order to increase production efficiency,obtain higher yield and protect ecological enviroment.The vegetable soybean Xiaonongqiuyan was taken as experimental material.The photosynthetic performance,agronomic traits and yield were investigated in different combinations of cultivation desity(100,150,200 thousand plants·hm^(-2))and fertilizer application amount(75,112.5,150 kg·hm^(-2)).The results showed that the Xiaononghongyan soybean obtained higher yield,better agronomic traits and stronger photosynthetic performance in the condition of cultivation density 150 thousand plants·hm^(-2) and nitrogen fertilizer application amount 112.5 kg·hm^(-2).In sum,decrement nitrogen fertilizer by 25%combined increased cultivation density could obtain higher yield and better agronomic traits in Xiaonongqiuyan,and be friendly to ecological enviorment.
