大果石笔木引种栽培研究
Journal of Southern Agriculture(2011)
Abstract
【目的】在柳州市引种种植大果石笔木,观察其对环境的适应性,为大果石笔木应用于园林绿化提供科学依据。【方法】在柳州市设点对大果石笔木进行物候期观察、种子繁殖、生长量测定及不同地点栽培试验。【结果】在柳州市气候环境条件下,大果石笔木种子繁殖发芽率达84.75%,年高生长达100.0cm以上,年茎粗生长达1.00cm以上;不同地点栽培的大果石笔木物候期基本一致,植株个体生长正常,树形丰满茂盛,均表现出较强的抗寒、抗旱、抗高温、抗病虫害能力,但耐涝能力较弱。【结论】大果石笔木适应柳州市自然气候环境条件,可作为乡土树种在柳州市城市园林绿化中推广应用。
