Abstract: The different trunk-stem cutting of barren tolerance elites clone of Cunninghamia lanceolata was treated in different season. The results indicated that rate of survival of the cutting with single-crown was higher than that of the cutting without crown by cottage propagation. And the height and ground diameter were significant different between them. Current year’s rate of survival, height and ground diameter were affected by cutting seasons. Current year’s height and ground diameter of cuttings in March or May were exceed the national standard, current year’s of height and ground diameter of cuttings in June were smaller because of the short growing period. With the cutting without crown before June, current year’s seedling wasⅠseedling of the national standard of clone of C. lanceolata, which could increase the use ratio of cutting wood, and was in favour of popularization and application of clone.
