| 摘 要： | 利用生物多样性作用机理进行不同作物间作套种是目前养分利用、生物抗病、化感作用和信息交换的研究热点。采用盆栽和田间小区试验方法，研究了烤烟间作草木樨对土壤养分的影响，结果表明，烤烟间作草木樨后对植烟土壤碱解氮和土壤速效磷含量的影响间作处理与单作处理比较没有显著差异，而在烤烟成熟中后期间作体系能不同程度地增加植烟土壤的速效钾含量，对平衡和协调土壤养分有积极的作用。

| Abstract: | The crop intercropping basing on biodiversity effect mechanism is a hotspot of nutrient utilization, disease resistant, allelopathy and information exchange. In this paper, field experiment and pot culture were conducted to study the effects of flue-cured tobacco and sweet clover (Melilotus officinalis lam.) intercropping on soil nutrient contents. The results showed that no significant difference of the contents of available nitrogen and available P was found between the treatment of intercropping and single cropping, but in the middle or late stage of flue-cured tobacco growth, the content of available K increased in the intercropping treatment, which might contribute to the balance of soil nutrients. |
