Effects of Fertilizer Formula and Brassinolide on Growth of Camellia oleifera

In order to study the best dosage of fertilizer and brassinolide (BR) for the growth of Chang-Lin 4, Chang-Lin 166 and Chang-Lin 18 camellia clones, L9(34) orthogonal experiment design was adopted to test the fertilizer formula and foliar spraying BRs for the three clones. The results are as follows: (1) Varieties is the critical factor affecting the growth index of camellia. (2) The weights of various factors affecting ground diameter, crown diameter, yield and net photosynthesis are in the order of variety, interaction among factors, fertilizing and BRs. Fertilizing has stronger effect on leaf SPAD value than the interaction among factors, while the latter has stronger effect on height growth than the former. The factors affecting the seeding rate are variety, fertilizing, BRs and interaction among factors. (3) With the treatment composition of Chang-Lin 18, N2P2K2 and 0.067 mg·L-1 BRs, the indexes of tree height, crown diameter and seeding rate are the highest. With the treatment composition of Chang-Lin 4, N1P1K1 and 0.067 mg·L-1 BRs, the ground diameter, leaf SPAD value and the yield are the highest. With the treatment composition of Chang-Lin 4, N2P2K2 and 0.033 mg·L-1 BRs, the daily average net photosynthesis rate is the highest.
