| Abstract: | High growth of Eucommia ulmoides was very fast between April and July, and reached peak in June. Diameter of Eucommia ulmoides grew rapidly between May and July, and two peaks appeared in June and September respectively.Fertilization in Eucommia ulmoides stand was the best in April and May.Fertilization quanlity was different with tree age. According to slope and mesa fertilization shoud be done in sink and hole patterns. |
| Keywords: | Eucommia ulmoides growth rhythm fertilization period fertilization quanlity fertilization methods |
