摘　　要：在高施有机肥、地下亚表层灌水、窄行密植栽培模式下,对大豆合农60及对照品种垦丰16地上部干物质变化动态进行分析。结果表明:合农60荚干重增加明显,后期干物重积累迅速。在高水肥和小垄密植栽培条件下,窄行密植品种间存在差异,合农60为抗倒伏,适合于窄行密植的高产品种。Under the high-organic fertilizer,underground subsurface irrigation,narrow row and dense growth cultivation,the dynamic changes of dry matter accumulation in above-ground of Henong60 and CK of Ken-feng16 were analyzed.The results showed that pod dry weight of Henong60 increased obviously,and dry matter accumulated rapidly at later period.In the context of high fertilizer and small ridge dense planting cultivation,varieties of narrow row and dense growth exist difference,Henong60 was lodging resistance,and it was the high yielding variety suitable for narrow row.
