Abstract:
Taking chicken manure, compound fertilizer, bioorganic fertilizer, specialty fertilizer for camellia as basal dressing and BRs with different concentrations of 0067 mg/L, 0033 mg/L and 0020 mg/L as top dressing according to Split Plot Design method, a twoyear experiment was conducted by successive sampling survey at different growing stages and specific indexes measurement to study the effect of applying varied types of fertilizers and different concentrations of BRs on the growth of ‘Ganwu’ Clone of Camellia oleifera. The results obtained were as follows:The optimal height growth of ‘Ganwu’ Clone plants was acquired by applying the compound fertilizer plus spraying 0020 mg/L of BRs; the maximum increment of the crown amplitude was got by applying the specialty fertilizer plus spraying 0020 mg/L of BRs. The highest SPAD value was obtained by spraying 0033 mg/L BRs top dressing; the most increase of SPAD value was got by applying the specialty fertilizer plus top dressing with 0067 mg/L of BRs. The highest N content in the leaves was got by spraying 0067 mg/L of BRs without any fertilizer application, which was followed by applying the specialty fertilizer plus spraying 0020 mg/L of BRs. The highest P content in the leaves was obtained by applying organic fertilizer plus top dressing with 0020 mg/L of BRs; the highest K content in the leaves was realized by applying the compound fertilizer plus spraying 0020 mg/L of BRs; whereas the highest dry matter content of leaves was obtained by applying the specialty fertilizer plus top dressing with 0033 mg/L of BRs.
