鄂西南山区不同幼林林下黄连种植模式优化研究

Optimization of compound planting mode of Coptis chinensis and different young forests at mountain areas of the southwest of Hubei

为了探寻适用于鄂西南山区不同幼林下栽种黄连的科学种植模式,采用比较法,用数据处理软件SPSSBase 11.5对不同种植模式中的黄连成活率、黄连产量及相关幼林的生长量、经济效益、生态效益和黄连有效成分含量进行了测算与分析。结果表明:日本柳杉-马桑-黄连乔灌草混交栽连模式,有利于幼林生长,有利于环境保护,且其经济效益比其他模式的要高,是一种比较科学的栽培方式,值得大力推广。同时认为,要逐渐减少以至杜绝采用传统的搭棚栽连模式。

In order to find out scientific compound planting mode of Coptis chinensis and different young forests at mountain areas of the southwest of Hubei, survival rate, production, activity ingredient of C. chinensis, increment, economic benefit and ecological benefit of young forests under different planting modes were measured, calculated analyzed by using comparative method and data processing software SPSS Base 11.5. The＇results show that the tree, shrub and herb compound planting mode of Cryptomeriajaponica-Coriaria sinica-C, chinensis are helpful for young forest growth and environment protection, and has higher economic benefit than other modes, so it is worth being extended as a more scientific cultivation mode. The C. chinensis planting mode under artificial shelter should be gradually reduced until completely eliminated.
