以益生菌、水温、寡糖和配合饲料为因素,仿刺参幼参的特定生长率为指标,通过L9(34)正交试验方法,研究4种因子对仿刺参幼参生长的影响,获得各因子的最佳组合参数。试验结果显示,4种因子对幼参特定生长率的影响均极显著(P<0.01),影响因素为益生菌>水温>寡糖>配合饲料。最佳的因素搭配为益生菌5mL/m3,水温24℃,壳寡糖+褐藻胶寡糖混合0.002g/L,幼参B型配合饲料。各因素水平对仿刺参幼参特定生长率影响为益生菌5 mL/m3>15 mL/m3>10 mL/m3,水温24℃>17℃>10℃,壳寡糖+褐藻胶寡糖>褐藻胶寡糖>壳寡糖,幼参饲料B型>幼参饲料加强型>稚参饲料。
Taking probiotics, water temperature, oligosaccharides and compound feed as the factors, the specific growth rate of S. ginseng was taken as the index. The effects of four factors on the growth of S. glabra were studied by orthogonal experiment L9 (34) Get the best combination of each factor parameters. The results showed that the four factors had significant effects on the specific growth rate of the ginseng (P <0.01). The influencing factors were probiotics> water temperature> oligosaccharides> compound feed. The best factor is probiotics 5mL / m3, water temperature 24 ℃, chitosan + alginate oligosaccharides mixed 0.002g / L, ginseng B type compound feed. The effects of various factors on the specific growth rate of S. ginseng were probiotics 5 mL / m3> 15 mL / m3> 10 mL / m3, water temperature 24 ℃> 17 ℃> 10 ℃. Alginate oligosaccharides> chitooligosaccharides, juvenile feed B type> juvenile feed enhanced> juvenile feed.
