摘　　要：为了研究不同种植参数对夏大豆产量和光合特性的影响,以夏大豆品种‘宝豆6号’和‘秦豆10号’为试验材料,采用4因素3水平的正交试验设计。结果表明:不同处理对夏大豆产量和光合性能的影响存在差异(P<0.05),处理3产量达最高,较其他处理高2.24%~24.27%,且净光合速率、胞间CO_(2)浓度、蒸腾速率优势明显,较其他处理分别高17.31%~61.44%、5.26%~28.62%和6.8%~9.36%;处理3叶片水分利用效率最高,其次是处理6,处理7最低,且花期的水分利用效率要优于鼓粒期;播期6月20日、密度15万株/hm^(2)、复合肥225 kg/hm^(2)和硼肥3.0 kg/hm^(2)分别具有较高的叶片水分利用效率。种植参数组合对夏大豆产量和光合性能具有显著影响,处理3为适宜的种植参数组合。To study the effects of different planting parameters on yield and photosynthetic characteristics of summer soybean,taking‘Baodou 6’and‘Qindou 10’as experimental materials,we set the orthogonal design(L934) with 4 factors and 3 levels.The results showed that:different treatments had different effects on yield and photosynthetic characteristics (P<0.05),the yield of treatment 3 was the highest which increased by 2.24%-24.27%compared with that of others;moreover,Pn,Ci,and Tr of treatment 3 were the highest,and they increased by 17.31%-61.44%,5.26%-28.62%,6.8%-9.36%compared with that of others,respectively;leaf WUE of treatment 3 was the highest,the next was treatment 6,and the last was treatment 7;leaf WUE of blooming period was higher than that of seed-filling phase;the planting date (20 June),planting density(150000 plants/hm^(2)),compound fertilizer (225 kg/hm^(2)),and boric fertilizer (3.0 kg/hm^(2)) had the highest leaf WUE in tested phase.The combination of planting parameters has a significant effect on the yield and photosynthesis performance of summer soybean,and treatment 3 is an optimal planting group.
