摘 要:为了系统研究野漆树轻型基质播种苗造林效果,在相同立地条件下,运用随机区组设计试验方法,对野漆树大田裸根苗和轻型基质苗进行造林对比试验,探讨2个类型苗木山地造林时,其造林保存率、林木生长量的差异。结果表明:野漆树2个类型苗木山地造林时在保存率、树高、地茎等方面都存在较大差异,且差异显著。轻型基质苗造林保存率平均达94.83%,大田裸根苗造林保存率达90.56%。轻型基质新造幼林1年生树高平均值为208.79cm,地茎平均值为30.2820mm。大田裸根苗新造幼林1年生树高平均值为124.39cm,地茎平均值为21.677mm。试验表明,用野漆树轻型基质苗造林,造林后的早期生长和保存率都优于常规的大田裸根苗。可以大力推广野漆树轻型基质育苗技术,特别是在石漠化、荒漠化土壤上,应积极提倡和推广应用野漆树轻型基质苗造林,具有重大的现实意义。In order to systematically study the effect of afforestation by light medium Toxicodendron succedaneum seedlings, the afforestation comparison trial of Toxicodendron succedaneum field bare-root seedlings and light medium seedlings was studied in the same site conditions, using a randomized block design test methods, to explore differences of afforestation survival rate and growth in the two types of seedlings mountain reforestation. The results showed that: the two types of Toxicodendron succedaneum seedlings mountain afforestation were quite different in terms of survival rate, tree height, basal diameter, and the difference was significant. The average survival rate of light medium seedlings was 94.83% and the survival rate of field bare-root seedlings was 90.56%. The average tree height and basal diameter of one year seedling with light medium reforestation method were 208.79 cm and 30.2820 mm respectively. While the average tree height and basal diameter of one year seedling with field bare-root reforestation method were 124.39 cm and 21.677 mm, respectively. The experiments showed that the early growth and survival rate of the seedlings using light medium seedlings afforestation method were better than conventional field bare-root seedlings. Therefore, it was of great practical significance to promote light medium Toxicodendron succedaneum seedlings afforestation method, especially on the stony desertification soil and desertification soil.
