油茶林梯壁栽植黄花菜植物篱生长效应研究

Growth Effect of Daylily Hedgerow Planted on the Terrace Wall of Oil-tea(Camellia oleifera Abel.)

通过在油茶林梯壁上栽植黄花菜植物篱研究复合模式的生长效应,结果表明:油茶和黄花菜复合经营林分群落结构比较合理,层次明显;油茶林梯壁套种黄花菜(YH)处理油茶总覆盖度(为85%)与油茶林梯壁未套种黄花菜(CK_1)处理(为47%)差异达极显著水平,YH处理油茶冠幅、春梢数量、春梢长度和单株产量分别比CK_1处理增加20.8%、29.2%、34.2%和24.8%,差异均达显著水平;油茶林梯壁套种黄花菜(YH)处理黄花菜与邻近相似立地条件边坡裸地种植黄花菜(CK_2)处理的平均株高、平均分蘖丛数、平均抽薹枝数、花蕾重、鲜蕾产量差异均不显著。

Growth effects of daylily hedgerow planted on the terrace wall of oil tea fields were studied.The results showed that the community structure of compound management stand consist of oil tea and daylily was more reasonable and the plant gradation was distinct.The coverage of oil tea interplanting daylily on the terrace wall（YH treatment）was very significant higher than the CK1 treatment（with no daylily interplantation）,and the crown diameter,the number of spring shoot,the length of the spring tip and the fruit yield were all significant higher than the CK1.And the plant height,average tiller number,average number of bolting branches,bud weight and fresh bud yield of daylily planted in the oil tea field were with no significant differences with those planted in the bare land nearby with the similar soil conditions（CK2）.
