摘　　要：为获得景观型木麻黄优良品种要建立采穗圃,为生产单位提供更多优良苗木,开展了木麻黄采穗圃密度试验,结果表明:圆头木麻黄为1.2m×1.2m,千头和垂柳木麻黄为1.0m×1.0m,龙柏和如意木麻黄为0.8m×0.8m较为适宜,得到的单位面积合格穗条数量及采穗可及度为最佳;圆头木麻黄截干促萌的高度为80cm,其他木麻黄高度为40cm。共培育景观型优质苗木5万株,造林成活率达90%以上,水培苗穗条采集可持续使用5年。In order to obtain the fine varieties of landscape-type CaswaWna ,provide more excellentseedlings for the production unit, the density test of Casuarina equisetifolia were conducted, result shows that the suitable planting density of cutting orchard of Casuarina equisetifolia 6 Yuantou is 1.2 m×1.2 m, Casuarina equi-setifolia 4 Qiantou and Casuarina equisetifolia Chuiliu are 1. 0 m×1. 0 Casuarina equisetifolia 6 Longbai7 ＆ Casuarina equisetifolia 〈Ruyi;〉 are 0. 8 m×O. 8 m〉 the number of qualified per unit area and the availability of cut-tings are the optimal. The sprout of truncation of Casuarina equisetifolia ‘ Yuantou’ are 80 cm. The height of other Casuarina equisetifolia is 40 cm. More than 50 thousand landscape-type seedlings were cultivated together, the col-lection of hydroponics seedlings of scions can be continuously used more than 5 years.
