| 中文摘要:根据商洛市五大道地中药材之一的南五味子人工栽培种植基地分布情况,进行土壤调查和样品分析。结果表明,商洛南五味子种植区土壤类型复杂,土壤理化性状和肥力水平差异较大。土壤质地、pH值、阳离子交换量(CEC)评价较好,土壤有效磷较高,处于优良级占总土样的90%,但土壤有机质、全氮、碱解氮、有效钾含量均有缺乏,处于较差级的分别占总土样的65%,60%,75%,25%,因此,在栽培中应注意增施有机肥,注重氮肥、钾肥的配合施用。 |

| Abstract:According to the distribution of Fructus schisandrae man-made planting base in Shangluo, soil surveys and sample analysis were conducted to study the soil fertility properties.The results showed that there were complex soil groups and significant differences in soil physical and chemical properties and fertility level in Shangluo Fructus schisandrae planting area.Soil texture,pH,CEC were in better level.The content of soil available phosphorus was comparatively high in which those ranked in the first grade(level) were 90% of the total soil samples.but the contents of soil organic matter,total nitrogen and available nitrogen and potassium are all insufficient,in which those ranked in the worsegrade(Ⅰ level) were 65%,60%,75% and 25% of the total soil samples respectively.So,increasing organic fertilizer application and cooperated application of nitrogen and potassium fertilizers should be payed more attention in Fructus schisandrae production. |
