摘要
为了寻求白浆土大豆最佳群体结构,提高白浆土大豆单产水平,采用不同基因型品种、不同种植行距、不同种植密度3因素3水平正交试验(正交表采用L9(34)),对白浆土大豆不同群体结构对大豆产量及其产量性状的影响进行研究。结果表明:品种(F=43.63>F0.01=18.00)和密度(F=18.03>F0.01=18.00)均达到极显著水平,行距(F=9.28>F0.05=6.94)达到显著水平,品种、密度和行距3个因素与产量关系密切,各因素以选用半矮秆品种‘合农60’、密度55株/m2、行距17cm组合群体产量最高,产量性状表现最佳。因此,采用矮秆品种,增加密度,缩小行距是目前提高大豆产量的重要途径。
The study is aimed to search the best population structure of soybean in albic soil,and increase the yield of soybean in albic soil.So,effect of different population structure of soybean on soybean yield and yield traits were studied in different genotype varieties,row spacings,densities in albic soil with 3 factors and 3 levels orthogonal test [using orthogonal table L 9(3 4)].The results indicated that:variety(F=43.63F 0.01 =18.00) and density(F=18.03F 0.01 =18.00) were both reached very significant level,row spacings(F=9.28F 0.05 =6.94) reached significant level.The relationships between yield and the three each factors of varieties,densities and row spacings were very close.Among all these factor conbinations,the yield achieved the highest when the semi-dwarf variety ' Henong60 ' was used in density of 55 plants/m 2 and row spacing of 17 cm,in which the performance of yield traits was the best.Therefore,using dwarf varieties,increasing density,reducing row spacing was an important way to improve soybean yield at the present time.
