胶药复合系统生态功能评价

Study on Evaluation of Ecological Function of Rubber and Medicinal Plant Compound System

通过构建橡胶—黄精的人工群落,研究土壤的容重、田间持水量、土壤养分含量、杂草防除效果和药材的主要有效成分含量。结果表明,胶药间种后的土壤容重、田间持水量、土壤养分含量等生态指标均有改善,杂草防除效果明显。胶药复合系统对于生态环境具有积极的调节功能。

Through constructing artificial community of rubber and Polygonatum,studying soil bulk density,field water holding capacity,soil nutrient content,weed control effect and contents of main active ingredients in medicinal materials.The results showed that the ecological indexes such as soil bulk density,field water holding capacity and soil nutrient content have improved effects after interplanting,the effect of weed control is obvious.Rubber and medicinal plant compound system has a positive regulation function on the ecological environment.
