在宁夏选择不同立地条件的造林试验区,进行了梭梭(H.ammodendron)人工造林试验研究,通过2年的调查研究,在地下水位较高,苗期管理规范的试验区,当年平均株高达47.98cm,平均地径0.53cm,第二年平均株高达93.21cm,平均地径0.91cm。梭梭当年造林根系生长快,第二年地上部分生长迅速,株高和地径增长率为94.3%和71.6%。沙质土壤平均成活率达79.25%,保存率达66.25%,说明我区部分地区立地条件和生态环境适宜梭梭生长,可以进行人工造林。
In afforestation experiment area of Ningxia, which chose different site conditions, the experiment of H. ammodendron afforestation was conducted. Through two years of investigation and study, in the experimental area with high groundwater table and standard management of seedling stage, 47.98cm, the average diameter of 0.53cm, average annual height of 93.21cm in the second year, with an average diameter of 0.91cm. In the same year, Haloxylon ammodendron grew fast and the aerial part grew rapidly in the following year. The growth rates of plant height and diameter were 94.3% and 71.6% respectively. The average survival rate of sandy soil was 79.25%, the preservation rate was 66.25%, indicating that the site conditions and ecological environment in some areas of our country are suitable for Haloxylon growth and afforestation can be carried out.
