| Abstract: |
| Under natural rainfed condition, factors affecting the growth, development, flowering and the productivity of ‘Ruhe’ (a tea chrysanthemum cultivar) were studied regarding cultivation techniques like transplanting method, planting density, the number of pinching and fertilization management. When planting seedlings‘Ruhe’with naked root were treated with the rooting powder, and covered with plastic film, a 2.42% increase was obtained compared to direct planting seedlings with naked root. Planting at row spacing 40 cm×40 cm with film covering showed higher plant height, canopy and flower yield per square meter than that of other treatments, with flower yields being 45 g·m-2, 58.33 g·m-2 higher than 30 cm×30 cm, 40 cm×40 cm row spacing and 236.67 g·m-2 higher than the 40 cm×40 cm row spacing. Flower per square meter for pinch once was 40 g and 20 g higher than pinch twice and control, respectively. Results of single fertilization experiment demonstrated N1 treatment promotes plant growth and performs better in number of branches, flower diameter, double layer flower, canopy breadth, plant total biomass than other treatments, with flower fresh weight, number and per square meter per plant flowers flower production being significantly higher for N1 and N2 treatments. In conclusion, the best practice for Shanxi forest land interplanting cultivation techniques of chrysanthemum tea is using naked-root transplanting with plastic film covering technology, setting the plant row spacing of 40 cm× 40 cm, pinching once, and using the N1 and N2 fertilization treatment. |
