邓恩桉容器苗培育新技术研究

Study on a New Container Nursery Technique of Eucalyptus dunnii Seedling

采用新的邓恩桉容器苗培育技术即在室内用平盘垫滤纸作发芽床,与室外采用黄心土98%+过磷酸钙2%和黄心土50%+火烧土48%+过磷酸钙2%作为苗床,进行邓恩桉种子播种及以后的芽苗移栽,培育容器苗。对比的结果表明:采用室内平盘垫滤纸作为发芽床比室外的2种方法发芽率提高了22.1%-34.8%,苗高生长提高了53.8%-98%,成本降低了18%-47%。

A new container nursery technique was sumitted in this paper,E.dunnii seeds were scattered on three seedling beds, one was used a plate with some filter paper indoor, the other was made of 98% yellow subsoil and 2% calcium super-phosphate, and another was made of 50% yellow subsoil and 48% burned soil and 2% calcium super-phosphate as the seedling beds. After bud shoots were transplanted and cultured into container-growing seedlings, the results indicated that the germination percent on flat plate with some filter paper on it indoor was 22.1%-34.8% and height growth was 53.8%-98% higher than on the other two seedling beds outdoor,but its cost was 18%-47% lower than the others.
