鄂西南山区不同幼林林下黄连种植模式优化研究

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。

林下黄连种植模式研究

通过对黄连(Coptis chinensis)不同种植模式中黄连成活率、黄连产量、相关林分的生长量、经济效益、生态效益和有效成分含量的研究,探索不同林分林下黄连种植模式。研究表明,日本柳杉林下栽连模式有利于林木生长,有利于环境保护,且经济效益比其他栽连模式高,是一种比较科学的栽培方式,应大力推广,同时要逐渐减少以致杜绝搭棚栽连模式。

Cultivation Techniques of Panax notoginseng F.H. Chen under Different Forests

To overcome the issues of high cost and continuous cropping obstacles in facility cultivation of Panax notoginseng_ F. H. Chen, satisfy the market demand, save the production cost, improve the utilization rate of forest land, increase the in-come of forest farmers and protect the ecological environment, the cultivation tech-niques of high-quality P. notoginseng seedlings from Wenshan, Yunnan under four kinds of forests （walnut forest, China fir forest, grape forest and kiwi forest） were in-vestigated in this study. The results showed that the height growth, crown diameter, survival rate and 3-year-old tuber weight of P. notoginseng_under walnut forest were higher than those under the other three kinds of forests; the height growth, crown diameter, survival rate and 3-year-old tuber weight of P. notoginseng under China fir forest were higher than those under grape forest and kiwi forest; and the crown di-ameter and survival rate under grape forest were higher, and the height growth and tuber weight under grape forest were lower than those under kiwi forest. Walnut is a broad-leaved deciduous tree species, so large-scale cultivation of P. notoginseng_should be conducted under broadleaf deciduous forest with canopy density around 0.8, taking advantage of the cool environment and rich humus layer under forest. This cultivation technology could save labor, shade, fertilizer and other costs, and accord with the ecological habit and the growth rules of P. notoginseng, thus im-proving yield and achieving high economic benefit.
