丹东太子参生境土壤养分测定与分析

对丹东地区5个典型野生太子参生境土壤进行取样和分析测定,为今后建立太子参规范化种植基地和科学合理施肥提供理论依据。结果表明,太子参生境土壤的酸碱度总体呈酸性;土壤有机质、全氮和碱解氮含量丰富;退耕还林土壤速效磷、速效钾含量稍缺,未耕作的土壤相对丰富。为此,如果进行人工栽培,应注意施磷钾肥。

Analysis of Nutrient in Habitat Soil of Radix Pseudostellariae in Dandong Area

Soil samples from five habitats of Radix Pseudostellariae in Dandong area were analyzed.It was found that the soil was generally acidic with rich content of organic matter,total nitrogen and alkali-hydrolyzable nitrogen.In areas returned from grain plots to forestry,the soil was slightly lack of rapidly available phosphorus and potassium,but was relatively rich in uncultivated under-tree soil.Consequently,attention should be paid to fertilizing phosphorus and potassium in artificial cultivation.
