| 【Objective】The response of Myrciaria cauliflora Berg to different fertilization and light treatments
were studied.【Method】Taking the 4-year-old raw M. cauliflora as experimental objects, the effects of different
fertilization and light treatments on the growth characteristics of M. cauliflora were studied.【Result】Different types
and concentrations of fertilizer were conductive to the increase in plant height, ground diameter and crown width of the
M. cauliflora. The maximum increase in plant height was found in the condition of 0.2 kg compound fertilizer/plant,
increased by 15.51% compared with that of non-fertilization(CK); The maximum increase in ground diameter of M.
cauliflora was found in the condition of 0.2 kg compound fertilizer/plant, increased by 8.49% compared with that of the
CK; The maximum increase in crown width of the M. cauliflora was found in the condition of 0.1 kg nitrogen fertilizer per
plant, increased by 15.37% compared with that of the CK. Different concentrations of fertilizer had the same effect on the
growth of ground diameter and plant height, but had different effects on crown width. The growth of ground diameter and
plant height increased with the increase of fertilization amount. The contents of chlorophyll a and b increased under the
treatments of different types and concentrations of fertilizers. Among all the treatments, the treatment with the compound
fertilizer of 0.2 kg/plant had the greatest effect on the improvement of chlorophyll a and b content; Shading of different degrees had no effect on the growth of plant height of M. cauliflora, but inhibited the growth of ground diameter and the
content of chlorophyll a and b to some extent.【Conclusion】The application of compound fertilizer of 0.2 kg/plant in
production had a promoting effect on the growth of plant height and ground diameter of M. cauliflora Berg. |
