摘要
以高海拔地区党参不同种植方式下种植土壤和党参植株为试材,采用野外调查与室内分析相结合的方法,研究了不同种植方式下高海拔地区党参种植土壤有机质、全氮、全磷、碱解氮及有效磷含量和党参不同部位中有机碳、全氮、全磷含量分布特征,并研究了不同种植方式下土壤与植株C/N、C/P及N/P化学计量比特征。结果表明:有机质表现为轮作>套作>间作>净作,全氮为间作>套作>轮作>净作,全磷轮作>间作>套作>净作,碱解氮为轮作>套作>间作>净作,有效磷为套作>轮作>间作>净作;根、茎及叶中有机碳含量表现为轮作>间作>套作>净作,根中全氮含量表现为套作>间作>净作>轮作,茎中全氮含量表现为间作>净作>轮作>套作,叶中全氮含量表现为间作>套作>净作>轮作,根中全磷含量表现为间作>套作>轮作>净作,茎中全磷含量表现为净作>间作>轮作>套作,叶中全磷含量表现为间作>轮作>套作>净作;土壤C/N和C/P表现为轮作>套作>净作>间作,土壤N/P为套作>间作>净作>轮作,叶中N/P比为净作>间作>套作>轮作。综合4种种植模式下土壤肥力、土壤养分供给能力,高海拔地区党参种植模式优先考虑间作,其次为套作。
Planting soil and Codonopsis pilosula plant in different planting patterns of Codonopsis pilosula in high altitude localities was studied as test material. The combination of field investigation and laboratory analysis was adopted. The content of planting soil organic matter, total nitrogen, total phosphorus, available nitrogen and available phosphorus under different planting patterns in high altitude area of Codonopsis pilosula, and the distribution characteristics of organic carbon, total nitrogen and total phosphorus of different parts of Codonopsis pilosula in high altitude area under different planting patterns, the stoichiometric characteristics of C/N, C/P and N/P of soil and plant under different planting patterns were studied. The results showed that the content of soil organic matter was being crop rotation〉relay intercropping〉intercropping〉single cropping, the content of soil total nitrogen was being intercropping〉relay intercropping〉crop rotation〉single cropping, the content of soil total phosphorus was being crop rotation〉intercropping〉relay intercropping〉single cropping, the content of soil available nitrogen was being crop rotation 〉 relay intercropping intercropping〉single cropping, the content of soil available phosphorus relay intercropping：〉 crop rotation〉intercropping〉single cropping. The content of organic matter in roots, stems and leaves was being crop rotation〉intercropping〉relay intercropping〉single cropping, the content of total nitrogen in roots was being relay intercropping〉intercropping〉single cropping〉〉crop rotation, the content of total nitrogen in stems was being intercropping〉single cropping〉crop rotation〉relay intercropping, the content of total nitrogen in leaves was being intercropping〉relay intercropping〉single cropping〉 crop rotation.

The soil C/N and C/P was being crop rotation〉 relay intercropping〉 single cropping〉 intercropping, the soil N/P was being relay intercropping〉 intercropping〉 single cropping〉 crop rotation, the leaves N/P was being single cropping〉intercropping〉relay intercropping〉crop rotation. The soil fertility and nutrient supply ability of the 4 kinds of planting patterns were integrated, and the intercropping was first considered in the high altitude area of Codonopsis pilosula, followed by relay intercropping.
