摘　　要：为充分发挥濮豆820基因优势,实现大豆高产、优质。文章研究不同种植密度和施肥量对濮豆820产量和品质影响。结果表明,种植密度和施肥量对大豆产量影响均显著。相同种植密度下,随着施肥量增加,大豆单株荚数、单株粒数、单株粒重和百粒重均呈升高趋势。相同施肥量下,随着种植密度增加,大豆单株荚数、单株粒数、单株粒重和百粒重均呈先增后降趋势。种植密度对大豆品质影响不显著,施肥量对大豆品质影响显著。当种植密度为19.5万株/hm^(2)、施肥量为300 kg/hm^(2)时,濮豆820产量和品质表现最佳。In order to give full play to the advantages of Pudou 820 gene and achieve high-yield and high-quality of soybean.This paper studied the effects of different planting density and fertilizer amount on yield and quality of Pudou 820.The results showed that planting density and fertilizer amount had significant effects on soybean yield.Under the same planting density,the number of pods per plant,the number of grains per plant,the weight of grains per plant and 100-grains weight increased with the increase of fertilizer amount.With the increase of planting density,the pod number per plant,kernel number per plant,kernel weight per plant and 100-grains weight of soybean increased first and then decreased.Planting density had no significant effect on soybean quality,fertilizer application amount had significant effect on soybean quality.We found that when planting density was 195000 plants/ha and fertilizer amount was 300 kg/ha,Pudou 820 could achieve high-yield and high-quality.
