Afforestation of Platycladus orientalis in Rocky Coast in Western Liaoning

Experiment on planting technology and survival ratio of Platycladus orientalis in rocky coast in western Liaoning were conducted by seeding age,planting season,hydrogel treatments,root treaments.The result shows that 1.5-year-old container seeding is suitable to be planted in rocky coast,there is no significant difference in spring,summer and autumn of uniform container seeding.Bare-root seeding with water immersion and take soil balling can enhance survival ratio availably before affoerstation.Using hydrogel to treat bare-root seeding has significant function on improving survival ratio and the optimal dose of hydrogel treatment is 200-250 g per hole.
