Effects of different arrangement density and fertilization treatment on the growth of Camellia osmantha
To investigate the effects of different arrangement density and fertilization treatment on the growth of Camellia osmantha,the 1-year cutting seedlings of Camellia osmantha Yichen were taken as experimental materials,and the seedling height,ground diameter,crown width,and biomass were measured under different arrangement density(no space between containers,5 cm between containers)and fertilization treatment(no fertilization,water soluble compound fertilizer 1.0 g/plant).The results showed that seedling height,ground diameter,crown width,fresh weight of above ground/lower part,and dry weight of above ground/lower part of seedlings in treatment 2(5 cm between containers,water-soluble compound fertilizer 1.0 g/plant)were the largest.Compared with treatment 1(5 cm containers spacing,no fertilization),the increase was 72.01%,63.89%,85.89%,224.93%,88.49%,169.80%,and 85.74%,respectively.The seedling height,ground diameter,crown width,fresh weight of the above/lower part,and dry weight of the above/lower part of the seedlings in treatment 2 were all greater than those in treatment 3(no space between containers,water-soluble compound fertilizer 1.0 g/plant).It can be seen that in the process of seedling cultivation,fertilization and the arrangement density of seedling containers are important factors affecting the quality of Camellia osmantha,treatment 2 has a good effect on the growth promotion of Camellia osmantha.
