以湘林1号油茶无性系为试验材料,研究喷施不同浓度的磷酸二氢钾、尿素、赤霉素、硼肥等4种叶面肥对其枝条和有效芽生长的影响。结果表明:硼肥和尿素对油茶新梢长生长、有效芽数量有极显著影响,4种叶面肥对新梢粗的影响不显著;对新梢长和有效芽生长效果最好的浓度和肥种组合是200 mg/mL的硼肥。
Effect of foliage dressing on the growth of Camellia oleifera branches and buds
With Xianglin NO.1 clone of Camellia oleifera as research object,the effects of different concentrations of mo-nopotassium phosphate,urea,gibberellin and boron fertilizer on the growth of Camellia oleifera branches and buds were studied.The results showed that,the boron fertilizer and urea had significant effect on the length growth of new shoot and the number of effective buds.Four kinds of foliar fertilization had relatively small effect on the diameter of new shoot.For growth of new shoot length and effective buds the best combination of fertilizer and concentration was 200 mg/mL boron fertilizer.
