摘要
24个大豆品种分别种植在2块不相邻的轻度盐碱地块与重度盐碱地块上进行大田试验。对24个不同大豆品种的形态性状和产量进行测定分析。结果显示,相对轻度盐碱条件,重度盐碱条件下大豆植株的株高、主茎节数、单株荚数、单株粒数、单株粒重的变化均有不同幅度减少,且减少幅度不同。与轻度盐碱条件相比,重度盐碱条件下各大豆品种产量均有所下降,下降幅度为14.3%~30.4%,且产量差异均达到显著水平,其中有6个品种达到极显著水平。铁豆119号和沈农豆38号产量下降比例较小,分别为14.3%、16.4%,说明铁豆119号耐盐碱性最优,沈农豆38号次之,福来豆168号产量下降比例最大,为30.4%,说明耐盐碱性最差。
A total of 24 soybean varieties were planted on two non-adjacent lightly saline alkali plots and heavily saline alkali plots,and field experiments were conducted.We measured and analyzed the morphological traits and yield of 24 different soybean varieties.The results showed that under severe saline alkali conditions,the changes in plant height,number of main stem nodes,number of pods per plant,number of grains per plant and grain weight per plant of soybean plants reduced in different degrees,compared to those under mild saline alkali conditions.Compared to mild saline alkali conditions,the yield of each soybean variety decreased by 14.3%-30.4%under severe saline alkali conditions,and the yield difference reached a significant level,with 6 reaching extremely significant levels.Tiedou 119 and Shennongdou 38 had lower proportion of yield decrease,which were 14.3%and 16.4%,respectively.Thus,Tiedou 119 had the best salt and alkaline tolerance,followed by Shennongdou 38,and Fulaidu 168 had the largest proportion of yield decrease(30.4%),indicating the worst salt and alkaline tolerance.
