Abstract
A forestation experiment was conducted by revegetating cutting slope using the method of seedling placement and growth base spraying. The experiment planted 11 specie container seedlings in a 4 kind of fields consisting of a 2 kind growth base (organic thick growth base material and inorganic thick growth base material) and a 2 kind growth base with a 5cm and 10cm thickness on a 45degrees of cutting slope of soft rock. The probability of survival of a young tree 3 years 7 months after planting was over 70 % for 8 species, while withered and dead plants were substantial for 3 species. Dead plants were common in the inorganic thick growth base material. Withered and dead plant patterns varied for first year to second year. For most species, tree height tended to be much more vigorous in organic thick growth base. The results suggest that when using the method of seedling placement and growth base spraying for cutting slope forestation, design and execution compatible with species and growth base are crucial.
