摘要
以十大功劳(Mahonia fortunei)、核桃(Juglans regia)、越南槐(Sophora tonkinensis)和玉米(Zea mays)为试验材料,研究十大功劳与其他3种植物间作对土壤化学性质的影响,并通过主成分分析法计算3种模式下土壤养分的综合得分,探索最合适的十大功劳间作模式,可为十大功劳规模化种植提供科学指导。结果表明,在十大功劳-越南槐模式下,土壤中的全氮、全磷、全钾、硝态氮、速效磷和速效钾含量分别为3.66 g/kg、2.66 g/kg、16.42 g/kg、38.76 mg/kg、231.37 mg/kg和305.43 mg/kg,均为最高;土壤养分综合表现为十大功劳-越南槐>十大功劳-玉米>十大功劳-核桃。
Taking Mahonia fortunei,Juglans regia,Sophora tonkinensis and Zea mays as materials,effects of in⁃terplanting of M.fortunei and different plants on chemical properties of soil were studied.Principal component analysis was made to compute comprehensive scores of soil nutrients in three interplanting models,and the most suitable interplanting model for M.fortunei was explored,which could provide scientific guidance for large-scale cultivation of M.fortunei.Results showed that contents of total nitrogen,total phosphorus,total potassium,nitrate nitrogen,available phosphorus and available potassium in soil of M.fortunei-S.tonkinensis model were 3.66 g/kg,2.66 g/kg,16.42 g/kg,38.76 mg/kg,231.37 mg/kg and 305.43 mg/kg respectively,which were the highest.Com⁃prehensive scores of soil nutrients were M.fortunei-S.tonkinensis>M.fortunei-Z.mays>M.fortunei-J.regia.
