摘　　要：2018—2019年在敦化市大桥乡试验基地,对适宜该生态区域的12个大豆品种进行了氮磷钾营养高效基因型筛选与研究。依据品种2年产量结果及考种数据,筛选出营养高效品种吉育301、吉育341、东盛2号。在减肥30%的情况下,营养高效品种显著提高了单株荚数、单株粒数和单株粒重,并实现较显著的增产。营养高效品种较非高效品种氮磷钾利用效率更高,需肥量的峰值更低,适合作为减肥增效品种用于大豆生产。12 soybean varieties,which were suitable for local ecological area,were used for high efficient screening tests of NPK nutrient and research in the experimental field of DaQiao township,DunHua,during 2018 to 2019.According to the results of 2 years'production and agronomic data,three soybean varieties with nutrient efficient soybean varieties were selected,which were JiYu 301,JiYu 341 and DongSheng 2.Reducing fertilizer by 30 percent,the nutritionally efficient varieties’pod number,grain number and grain weight per plant were significantly raised and with a higher production.Nutritionally efficient varieties with a higher NPK utilization efficiency and a lower peak value of optimal fertilizer requirement than non-efficient varieties.they are suitable for soybean production under reduced fertilizer conditions.
