摘要
在油茶(Camellia oleifera)林和桉树(Eucalyptus spp.)林林下套种葫芦茶(Tadehagi triquetrum)、糙毛假地豆(Desmodium heterocarpon var.strigosum)、大叶山蚂蝗(Desmodium gangeticum)、大翼豆(Macroptilium lathyroides)4种牧草,用株高、分支、冠幅等参数表征其生长状况,检测它们的生长情况的变化。结果表明:桉树林下葫芦茶的株高、分支、冠幅分别为:(81.7±5.5)cm、(9.4±6.2)条、(5685.6±3 452.1)cm2,生长良好;而油茶林下糙毛假地豆的株高、分支、冠幅分别为:(20.2±3.4)cm、(44.6±24.6)条、(3 673.3±2 675.2)cm2,生长状况最好;大叶山蚂蝗在两种林下的成活率低,生长不良;大翼豆容易攀附于上层植物中,不适合在林下种植。葫芦茶和糙毛假地豆都可套种于林下,但葫芦茶更适于桉树林下套种;糙毛假地豆更适于油茶林下套种。
Under Camellia oleifera and Eucalyptus plantations, four kinds of forages were set up, including Tadehagi triquetrum, Desmodium heterocarpon var. strigosum, Desmodium gangeticum, and Macroptilium lathyroides. Changes of growth index（height, branch and crown width） of four forages were investigated and analyzed. The result shows that the height, branch and crown width of Tadehagi triquetrum under Eucalyptus plantation are（81.7±5.5） cm,（9.4±6.2） branches,（5 685.6± 3 452.1） cm^2, respectively. The height, branch and crown width of Desmodium heterocarpon var. strigosum under Camellia oleifera plantation are（20.2±3.4）cm,（44.6±24.6） branches,（3 673.3±2 675.2） cm^2, respectively. Both the growths of Desmodium gangeticum and Macroptilium lathyroides are poor under plantations. These two kinds of forages are not suitable for planting under the forest. We conclude that both Tadehagi triquetrum and Desmodium heterocarpon var. strigosum can be planted under the two plantations. While Tadehagi triquetrum is more suitable for planting under Eucalyptus plantation, Desmodium heterocarpon var. strigosum is more suitable under Camellia oleifera plantation.
