摘　　要：在地处闽西北的永安市开展山牡荆栽培适应性试验,通过多年定位观测,结果表明:山牡荆具有较强的适应性和速生性,造林成活率可达95%以上,幼林林分保存率达85%。在轻微受冻或不受冻情况下,其当年树高可达0.9 m、地径在1.0 cm以上,造林后第2年开始生长较为迅速。第5年林分开始郁闭并进入速生期,7.5年生的林分平均树高、胸径、冠幅分别达8.76 m、9.86 cm和3.12 m,年均树高、胸径达1.17 m和1.31 cm;山牡荆可耐不超过-4℃且持续时间2 d以内的短暂寒流霜冻,即在该极端低温和持续时间范围内,幼林可能会出现轻微至中度冻害,但可恢复生长;此外,山牡荆抗风性、耐旱性和抗病虫害能力较强。其适合在年均19℃以上、极端低温不低于-4℃的区域栽培。The adaptability test of Vitex quinata cultivation was conducted in Yongan City,located in the northwest of Fujian Province.Through years of positioning observation,the results showed that V.quinata had strong adaptability and rapid growth,with the survival rate of afforestation reaching more than 95%and the preservation rate of young stands reaching 85%.In the case of slight freezing or no freezing,the height of the tree in the current year can reach 0.9 m,and the ground diameter was more than 1.0 cm.After afforestation,it begins to grow rapidly in the second year.In the fifth year,the stand began to close and entered the fast-growing period,and the average height,DBH and crown width of 7.5 a trees were 8.76 m,9.86 cm and 3.12 m respectively,the average annual tree height and DBH of the fast-growing stand were 1.17 m and 1.31 cm,respectively.V.quinata can withstand short cold current frosts that do not exceed-4℃and last for less than 2 days,that is,within the extreme low temperature and duration range,the young forests may suffer slight to moderate frost damage,but growth can resume;In addition,V.quinata has strong wind resistance,drought resistance and disease and insect resistance.It is suitable for cultivation in areas where the annual average temperature is above 19℃and the extreme low temperature does not below than-4℃.
