Effects of Different Shading Treatments on the Euonymus japonicus

Effect of different periods and different shading treatments on the chlorophyll content, height of seeding, diameter growth of Euonymus japonicus were researched. The results showed that in 70%, 50%, 30% shading treatments and full exposure treatment, the Euonymus japodicus growth in the 50% shading treatment was the most apparent and the growth was apparently larger than growth in full exposure treatment, in 70% and 30% shading treatments. In the whole growing process, different treatments could increase the chlorophyll contents, and were higher than full exposure treatment, and in the 70% shading treatment, the chlorophyll content was the highest. The chlorophyll contents orders were:70% shading treatment 50%shading treatment 30% shading treatment full exposure.
