为了明确黑龙江省不同年代育成大豆品种对施肥水平响应的变化趋势，以黑龙江省不同年代育成的合丰25、合丰35、绥农14、合丰39、垦丰16等5个主栽大豆品种为材料，研究不同年代育成大豆品种在不同施肥水平条件下农艺性状及产量因子的变化规律。结果表明，黑龙江省不同年代育成大豆品种在不同施肥水平条件下，单株产量、主茎节数、单株荚数、光合速率等性状改良效果明显，株高、主茎节数、单株粒数、单株叶面积也得到了不同程度的改良，单株叶面积向着更适于密植栽培的清秀型发展；农艺性状和产量因子对低施肥水平适应能力的改良主要是由于单株荚数显著提高的结果；对中等施肥水平适应能力改良主要是由于光合速率显著提高的结果；对高施肥水平适应能力增强主要是由于光合速率和主茎节数极显著提高的结果。

This study aims to elucidate the response to fertilization of soybean cultivars,which were released in dif-ferent years in Heilongjiang province,such as Hefeng 25,Suinong 14,Hefeng 39,Kenfeng 16,and Hefeng 35,by in-vestigating agronomical traits and yield component .The results showed that yield per plant,main stem nodes,number of pods per plant and photosynthetic rate improved significantly,and plant height,main stem nodes,grain per plant and leaf area per plant as well .The leaf area per plant was the suitable index .Improvement in agronomical traits and yield component under low fertilization was mainly due to the increase in number of pods per plant,and that under medium fer-tilization due to the increase in photosynthetic rate,under high fertilization due to the increase in photosynthetic rate and main stem node number .
