Abstract:

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 were124.39 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.
