摘要: 以大豆[Glycine max (Linn.) Merr.]品种鄂豆8号为试验材料,采用两因素随机区组试验,研究烯效唑和亚硫酸氢钠对大豆的产量及农艺性状的影响。结果表明,不同浓度烯效唑和亚硫酸氢钠的处理对大豆均可起到增产的作用,不同浓度烯效唑处理间的大豆产量差异未达显著水平;烯效唑与亚硫酸氢钠间的互作对大豆产量的差异影响也未达显著水平,但不同浓度亚硫酸氢钠处理间的大豆产量差异达极显著水平;单株有效分枝数、单株有效荚数、单株粒数及单株粒重随着亚硫酸氢钠喷施浓度的提高都有不同程度的增加,在200 mg/L处理下最高;试验以100 mg/L的烯效唑+200 mg/L的亚硫酸氢钠(A2B3)处理的平均产量最高,在主茎节数、有效分枝数和单株有效荚数性状上也表现最高。

Abstract: Taking soybean[Glycine max (Linn.) Merr.] variety Edou No.8 as experimental material, the effects of uniconazole and NaHSO3 on yield and agronomic traits of soybean were studied by two-factor randomized block experiment. The results showed that different concentrations of uniconazole and NaHSO3 could increase the yield of soybean,and there was no significant difference in soybean yield among different concentrations of uniconazole. The interaction between uniconazole and NaHSO3 had no significant effect on soybean yield, but the difference in soybean yield between different concentrations of NaHSO3 treatment was extremely significant. The number of effective branches per plant, the number of effective pods per plant, the number of grains per plant and the grain weight per plant increased with the increase of NaHSO3 concentration, and the highest was at 200 mg/L treatment. The average yield of the treatment of 100 mg/L uniconazole + 200 mg/L NaHSO3 (A2B3) was the highest, and the number of main stem nodes, effective branches and effective pods per plant were also the highest.
