进行了田间试验和植物及土壤分析。NPK三要素及包括全部必需元素的完全营养液田间试验,均无显著肥效,~(32)p、~(83)R_b凡示踪试验证明,吸自肥料磷、钾占人参全量磷、钾的百分率(pdff和kdff)确实甚小(<5％)。有机培肥试验中,大于土壤腐殖质4％的有机质增量,不表现产量效应。从人参需肥量仅为农作物的1/6,土壤(参床土壤含腐殖质>8％)供肥远过于求角度,论证了施肥无效的原因。提出了现行栽培制度下无须施肥的论断,和人参推广到淋溶黑土上种值无须伐林的建议。

Field trials and plant and soil analyzes were conducted. NPK three elements and complete nutrient solution including all the necessary elements in the field test, no significant fertilizer, ~ (32) p, ~ (83) R_b Where tracer test showed that the absorption of fertilizer phosphorus, potassium, total phosphorus, potassium Percentages (pdff and kdff) are really small (<5%). In the organic fertilization experiment, the increase of organic matter more than 4% of the soil humus did not show the yield effect. From the ginseng required fertilizer is only 1/6 of the crop, the soil (soil with humus> 8%) is too far to supply fertilizer, proving the reason of ineffective fertilization. Propose the suggestion that no fertilization is needed under the current cultivation system and the suggestion that the ginseng should be popularized to the leaching black soil without deforestation.
