Research on Cutting Seedling Cultivation Technology of Abies chensiensis Tiegh. in Shade Shed

Abstract

As a unique tree species in China, Abies chensiensis Tiegh. boasts hardwood that is both strong and corrosion-resistant, thus possessing significant economic value. However, due to its specific growth environment and anthropogenic damage, the population of Abies chensiensis Tiegh. is gradually decreasing. Therefore, the protection and propagation of this species are particularly crucial. In terms of propagation, cuttage technology is an effective method for Abies chensiensis Tiegh. By selecting appropriate cutting seasons, cutting substrates, and cutting branches, the survival rate of cuttings can be improved. This study conducted a screening investigation on the cutting season, cutting substrate, and cutting maturity of Abies chensiensis Tiegh. under shade shelter conditions and drew the following conclusions: (1) There is a competitive relationship between rooting and decay during the cutting process; (2) Abies chensiensis Tiegh. belongs to a species with difficulty in rooting, and its suitable cutting season is from the middle to late June to the middle of July; (3) By selecting semi-lignified branches and substrates with good permeability, water retention, and nutrition for cuttings, a survival rate of 45.8% can be achieved. This study provides a beneficial exploration and reference for the cutting propagation of Abies chensiensis Tiegh.
