尾叶桉为桃金娘科桉属树种,梅县近几年引种在各水土流失区大量栽植,特别是在谷坊、拦沙坝等地栽种更多,梅县位于北纬20°10′～24°44′东径115°45′～116°35′,属中亚热带气候,具特点是冷热分明、干湿显著。年平均气温21.2℃,年降雨1400～1800mm,山地丘陵成土母岩主要有花岗岩,砂岩、流纹岩等,水土流失区的土壤多为瘦瘠、干旱、含砂石量较大之地。尾叶桉在这些地区都能生长,且表现良好。实践证明,尾计桉是一种较理想的水土保持树种。
Eucalyptus urophylla is Myrtaceae Eucalyptus species, Meixian introduced in recent years a large number of soil erosion areas planted, especially in the valley, barrage and other places planted more, Meixian located at latitude 20 ° 10 ’~ 24 ° 44 ’east 115 ° 45’ ~ 116 ° 35 ’, is a sub-tropical climate, characterized by distinct hot and cold, significant wet and dry.
