摘　　要：以人参(Panax ginseng C.A.Mey)茎叶总皂苷为评价指标,研究平地栽参不同土壤改良的最优方案。试验以二次回归正交旋转设计为基本数学模型,研究玉米秸秆、猪粪、鹿粪、拮抗菌、菌糠5种基质的不同组合对人参茎叶总皂苷含量的影响。模型解析发现,在相同的栽培条件下,5种基质对人参茎叶总皂苷含量的贡献从大到小为猪粪、鹿粪、玉米秸秆、菌糠、拮抗菌。计算机模拟寻优表明,玉米秸秆施用量6.64kg/m2,猪粪施用量3.24 kg/m2,鹿粪施用量3.48 kg/m2,拮抗菌施用量6.87 g/m2,菌糠施用量7.02 kg/m2条件下,人参茎叶总皂苷含量预测值为17.81%。综上这些栽培因素的组合可以作为平地栽培人参的推荐方案。Total saponin of ginseng（Panax ginseng C.A.Mey） stem and leaf was taken as an index to appraise and study the best proposal of soil improvement treatment.Effects of different combination of maize straw,stool of pig,stool of deer,antagonistic bacteria and spent mushroom substrate on total saponin content of ginseng stem and leaf were studied by using quadratic regression and orthogonal rotation as fundamental mathematic model.The Model Analysis showed that under the same cultivation conditions,the contribution of five substrates to ginseng saponin content ranking from the largest to the smallest was pig manure,deer dung,corn stalks,waste materials from fungal and antagonistic bacteria.Computer similated selection showed that when the application dosage of maize straw was 6.64 kg/m2,stool of pig was 3.24 kg/m2,stool of deer was 3.48 kg/m2,antagonistic bacteria was 6.87 g/m2,spent mushroom substrate was 7.02 kg/m2,the predictive value of total saponin of ginseng stem and leaf was 17.81%.In conclusion the assemblage of these cultivation factors could be recommended as a program of planting ginseng on farmland soil.
