  • 摘要: 【目的】探讨不同浓度富氢水(HRW)对大豆产量和品质的影响,为富氢水在大豆高产优质栽培中的应用提供理论依据。【方法】设不同浓度富氢水0(CK)、30%HRW、60%HRW处理,大豆幼苗长至株高约15 cm时,挑选长势一致的幼苗转移至室外进行盆栽试验,每周浇灌不同浓度富氢水(每盆1.5 L)至大豆成熟期,收获后分别对比不同处理的大豆植株表型和根瘤数量,并测定大豆生物量、单株荚数、单株籽粒数、百粒重、蛋白质和脂肪含量等产量和品质相关指标,评价不同浓度富氢水处理对大豆产量和品质的影响。【结果】与CK的生长指标比较,30%HRW处理的大豆地上部和根系干重均显著增加(P<0.05,下同),单株根瘤数显著减少;而60%HRW处理的大豆株高、单株根瘤数和根系干重与CK均无显著差异(P>0.05,下同)。与CK的大豆产量相关指标比较,30%HRW处理的单株荚数显著增加48.72%,单株荚重显著升高78.40%,单株粒数显著增加58.71%,百粒重增加18.92%;而60%HRW处理的单株荚数减少14.10%,单株荚重显著降低24.73%,单株粒数显著减少23.23%,百粒重降低22.44%。与CK的大豆品质相关指标比较,30%HRW处理的大豆蛋白质含量和脂肪含量差异不显著,而单株籽粒蛋白质总量显著增加84.94%,单株籽粒脂肪总量显著增加78.12%;60%HRW处理的蛋白质含量显著降低,而脂肪含量差异不显著,单株籽粒蛋白质总量显著降低56.37%,单株籽粒脂肪总量显著降低39.84%。【结论】30%HRW可改善大豆生长,显著增加大豆植株生物量积累,同时提高大豆籽粒产量和品质。

     

    Abstract: 【Objective】The present study aimed to investigate the effects of different concentrations of hydrogen-rich water(HRW)on soybean yield and quality, in order to provide a theoretical basis for its application in high-yield and high-quality soybean cultivation. 【Method】With different concentrations of hydrogen-rich water 0(CK), 30% HRW, 60% HRW treatment, when the soybean seedlings grew to about 15 cm high, the soybean seedlings with consistent growth were selected and transferred to the outdoor for pot experiment, different concentrations of hydrogen-rich water(1.5 L per pot) were poured every week until the soybean maturity period. After harvest, the phenotypic characteristics and number of root nodules of soybean plants were compared among different treatments. Additionally, biomass, pod number per plant, kernel weight per plant, 100-kernel weight, protein content and fat content were measured to assess the effects of hydrogen-rich water on soybean yield and quality. 【Result】Compared with the growth indicators of CK, 30%HRW treatment significantly increased both aboveground and root dry weights(P<0.05, the same below) while decreased nodule numbers per plant. No significant differences were observed in terms of plant height, nodule number per plant and root dry weight between 60% HRW treatment and CK(P>0.05, the same below). In comparison to soybean yield related indicators of CK, treatment with 30% HRW resulted in a significant increase in pod number per plant(48.72%), pod weight per plant(78.40%), kernel number per plant(58.71%), and an increase in 100-kernel weight(18.92%); while treatment with 60% HRW resulted in a decrease in pod number per plant(14.10%),a significant decrease in pod weight per plant(24.73%),a significant decrease in kernel number per plant(23.23%) and a decrease in 100-kernel weight(22.44%). Compared with soybean quality related indicators of CK, the protein content and fat content of 30%HRW treatment were not significantly different, but the total protein content of kernel per plant significantly increased by 84.94%, the total fat content of kernel per plant by 78.12%; the protein content in 60% HRW treatment significantly decreased, while difference in fat content was not significant, the total protein content of kernel per plant significantly decreased by 56.37%, and the total fat content of kernel per plant significantly decreased by 39.84%. 【Conclusion】The application of 30% HRW can enhance soybean growth, significantly increase plant biomass accumulation, and improve both soybean yield and quality.
