Abstract

The invention discloses a cutting propagation method of cryptomeria fortunei. The method includes the following steps that 1, cutting pretreatment is conducted; 2, exogenous hormones NAA50-150 ppm + IBA100-300 ppm are used, and cuttings are soaked for 0.5-1.5 h; 3, cutting is conducted; 4, after-management of cutting is performed. According to the cutting propagation method of cryptomeria fortunei, it is proved by experiments that under the conditions that exogenous hormones NAA150ppm + IBA100ppm are adopted and the cuttings are soaked for 1.5h, the rooting rate of the cryptomeria fortunei cuttings can reach 98.33%, the survival rate of the cuttings is increased, and the root growth can be promoted. The method is simple and feasible, and reliable seedling sources are provided for fast-growing and high-yield cryptomeria fortunei forest planting.

Description

technical field

[0001] The invention belongs to the technical field of plant cuttings, and in particular relates to a method for propagating cedar cuttings. Background technique

[0002] Cedar is a genus in the family Taxaceae. Plant taxonomists believe that the Cryptomeria fortunei can be divided into two species, namely Cryptomeria fortunei and C.japonica. The growth height of cedar can reach about 40m, and the diameter at breast height can reach more than 2m. Cedar is an evergreen tree, and it is also cultivated in southern Jiangsu, Zhejiang, Henan, Jiangsu, Shandong, Anhui and other provinces, and the growth of Cedar is good. The general growth height of cedar is: the leeward sunny place at an altitude of 400m ~ 1400m, often mixed with some broad-leaved tree species such as Castanopsis eyrei Tutch. 14~19℃, the average temperature in January is above 0℃. Cedar has fast growth speed, light and soft material, straight texture, high strength, strong corrosion resistance,...
