[目的]研究等离子体不同次数处理大豆(Glycine max L.)种子对其生物学性状、产量及产值的影响,为等离子体处理大豆种子技术的应用提供理论依据。[方法]试验共设7个处理,处理1应用剂量1.0A×1次,处理2应用剂量1.0A×2次,处理3应用剂量1.0A×3次,处理4应用剂量1.0A×4次,处理5应用剂量1.0A×5次,处理6应用剂量1.0A×6次,处理7为对照(CK)。[结果]等离子体处理的大豆种子能明显提高苗期的根系数,并提高开花率、结荚率;各处理比对照增产23.0～315.0 kg/hm2,增幅达0.9%～12.6%,增值74.8～1 126.0元/hm2。处理2效果最好,与对照相比,增产、增幅、增值最高,分别为315.0 kg/hm2、12.6%、1 126.0元/hm2。[结论]等离子体处理大豆种子的最佳次数为2次,增产、增收效果显著,这可为大豆优质、高产、高效栽培技术的广泛应用提供有力的技术支撑。
[Objective] The research aimed to study the effects of plasma treatment of soybean (Glycine max L.) seeds on its biological characters, yield and yield, and to provide a theoretical basis for the application of plasma treatment of soybean seeds. [Method] The experiment consisted of 7 treatments, 1 treatment dose 1.0 A × 1 treatment, 2 treatment dose 1.0 A × 2 treatment 3 treatment dose 1.0 A × 3 treatment 4 treatment dose 1.0 A × 4 treatment, Treatment 5 application dose 1.0A × 5 times, treatment 6 application dose 1.0A × 6 times, treatment 7 for the control (CK). [Result] The plasma-treated soybean seeds could significantly increase the root coefficient at seedling stage and increase the flowering rate and pod rate. The yield of each treatment was 23.0-315.0 kg / hm2, an increase of 0.9% -12.6% 1 126.0 yuan / hm2. The treatment 2 had the best effect. Compared with the control, the yield, increase and increment were the highest, which were 315.0 kg / hm2, 12.6% and 1 126.0 yuan / hm2, respectively. [Conclusion] The optimum number of time for plasma treatment of soybean seeds was 2 times, and the effect of increasing yield and income was remarkable. This could provide strong technical support for the wide application of high quality, high yield and high efficient cultivation techniques of soybean.
