为缓解参林矛盾,发展人参生产,在比较研究长白山区现行栽参土壤基础上,在公主岭少腐殖质中厚黑土上开展了栽培人参试验。获得了平均单产鲜参1.28kg/m~2、高产处理1.47kg/m~2的结果。三年生育情况、产量和品质,一致显示施用占床土重5%至30%草炭、15—30kg/m~2猪粪处理,无明显差异;施用磷酸二铵低于等磷量的重过磷酸钙(5%水准);掺砂显著(1%水准)低于无砂。讨论了土壤理化因素对人参生产的影响。初拟了较长白山区栽参土壤为低的宜参土壤指标。
In order to alleviate the contradictions of forest resources and develop the production of ginseng, a ginseng cultivation experiment was carried out on the medium-thick black soil with less humus in Gongzhuling based on a comparative study of the existing planting soil in Changbai Mountain. The average yield of fresh shoots 1.28kg / m ~ 2, high yield 1.47kg / m ~ 2 results obtained. Three-year fertility status, yield and quality consistently showed no significant difference in the application of peat at 5% to 30% of bed soil and pig manure at 15-30 kg / Calcium phosphate (5% level); Adulterated sand significantly (1% level) lower than no sand. The influence of soil physical and chemical factors on ginseng production was discussed. In the beginning, soil parameters of planting ginseng in Changbai Mountain were suggested to be low.
