| 【Objective】In order to obtain an excellent fertilization scheme,study on the effects of different
fertilizer treatments on Cerasus campanulata was carried out by using the one-year-old container seedling as material.
【Method】Using a randomized complete block design,the study set up four kinds of fertilization treatments consisting
of chicken manure, NPK compound fertilizer and liquid fertilizer,and compared the growth indexes of C. campanulata.
【Result】The growth rate of plant height,ground diameter,crown diameter,number of branchlet,length of branchlet and
number of leaves in fertilizer treatment groups were higher than those of the group without fertilizer (CK). The group which
applied chicken manure 20 g per seedling in autumn (F1) obviously promoted C. campanulata growth,and the increments
of growth indexes were significantly better than those of CK. The average increments of plant height,crown width andbranchlet length of F1 were 120.88, 81.18 and 79.94 cm, respectively,which were 1.99, 3.13 and 1.97 times of those of CK. The
ground diameter, number of branchlet, and number of leaves of F1 were 10.34 mm, 9.00 and 111.00. The group which applied
chicken manure 15 g per seedling and NPK 5 g per seedling in autumn (F2) was significantly inferior to F1 only in the number
and length of branchlet. There were significant differences between the groups which applied NPK and liquid fertilizer in spring
and summer (F3 and F4) and CK only in ground diameter and plant height,and the growth indexes except for ground diameter
increment were significantly smaller than that of F1.【Conclusion】Applying fertilizer could effectively promote the growth of
C. campanulata. Under the test conditions,the best fertilization scheme for one-year-old container seedling of C. campanulata is
applying chicken manure 20 g per seedling in autumn. |
