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

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).
