不同栽培模式对油茶林下多花黄精生长的影响

Effects of Different cultivation patterns on polygonatum cyrtonema under the camellia oleifera Forest

摘要:

采用多花黄精根茎繁殖苗在油茶林下开展不同栽培模式种植效果比较 。结果表明:在容器、大田和油茶林下三 种栽培模式下,多花黄精平均株高和平均地径大小为:容器>大田>林下,且容器栽培显著高于大田和油茶林下栽培,平均 块茎鲜重大小为:容器>林下>大田,容器和油茶林下显著高于大田栽培 。 三种栽培模式对多花黄精地下块茎多糖、黄酮 和薯羰皂苷元等活性成分含量大小均为:林下>大田>容器,且林下栽培显著高于大田和容器栽培 。 三种不同油茶密度对 多花黄精地径、株高和根茎鲜重影响均为:D1>D2>D3,其中平均株高 D1显著高于 D2和 D3, D1根茎鲜重显著高于 D3。 不同坡位对多花黄精生长有一定影响,株高下坡位>上坡位>中坡位。

Abstract:

The effects of different cultivation patterns of polygonatum cyrtonema rhizome propagation seedlings in ca- mellia oleifera forest were compared. The results showed that the average plant height and ground diameter of polygona- tum cyrtonema under container, field and camellia oleifera forest were:container > field > forest, and container cultiva- tion was significantly higher than that under field and camellia oleifera forest, the average fresh weight of tuber was : con- tainer > forest > field, container and camellia oleifera forest were significantly higher than that under field cultivation . The contents of polysaccharide, flavone and diosgenin in rhizome of polygonatum cyrtonema were:under forest > field > container, and under forest cultivation was significantly higher than that in field and container . The effects of three differ- ent density of camellia oleifera on the diameter, plant height and fresh weight of rhizome of polygonatum cyrtonema were:D1> D2> D3, the average plant height D1was significantly higher than D2and D3, and the fresh weight of rhizo- me D1was significantly higher than D3. The growth of polygonatum cyrtonema was affected by different slope position . The plant height was lower slope position > upper slope position > middle slope position .
