[0001] The invention relates to a method for raising seedlings by cuttings, in particular to a method for raising seedlings by cuttings of Alnus chinensis, belonging to the technical field of alders cultivation in the south of the Yangtze River. Background technique

[0002] Jiangnan alder (Alnus trabeculosa Hand.-Mazz.) is a deciduous tree belonging to the Betaceae Alder family, with a height of 25 m and a diameter at breast height of 40 cm. 400 mm hills and mountains, it can also grow on hillsides with drier soil. Alder grows quickly and becomes a forest quickly, and it grows well on deep, moist soil. It grows more than 1 m or even 2 m in one year, and generally becomes a forest in three years, but it grows slowly in places with poor soil. Its peak growth period is 5-15 years, and the peak period of DBH is 10-15 years, so it is suitable for short-rotation afforestation, and then it can be regenerated by budding. Jiangnan alder is light reddish-brown in c...
