野生豆科植物三点金的无性繁殖研究

研究了三点金Desmodium tiflourum营养体在广东亚热带气候条件下的快速繁育技术，结果表明：三点金适应性强，适宜在多种土壤条件下生长，在不同类型的土壤上栽植成活率平均达83%以上，其中以砖红壤上栽植成活率最高，平均达96%；春、夏、秋三季均可进行栽植，其中7月栽植成活率高达98%；不同的无性繁殖方法繁育或建坪成活率在92%以上，最高可达98%；植株材料的保湿，避免失水萎蔫是提高成活率的关键因素；无性繁殖或建坪最优基质是砖红壤，最适宜的季节是夏季。

Study on asexual propagation of the wild leguminous plant of Desmodium tiflourum

Rapid reproduction technique of nutritive part of Desmodium tiflourum in subtropical climate of Guangdong was studied.The results showed that D.tiflourum was adapted to various soil conditions,and its average planting survival rate in various soil was over 83%,with 96% in latosol.The D.tiflourum could be planted in spring,summer and autumn,and the survival rate reached 98% in July.The survival rate of various asexual propagation methods was more than 92%,and the highest rate was 98%.Plant moisture retention...
