Abstract

The invention discloses a method for cutting seedling-raising of Alnus trabeculosa. The method is characterized by comprising the following steps: (1), collection and treatment of a stalk for cutting; (2), arrangement of a cutting bed; and (3), cutting on the cutting bed. The cutting method provided by the invention has the advantages that the rooting rate of Alnus trabeculosa is high, original properties of plants can be retained, propagation of Alnus trabeculosa is accelerated, and the market demand for garden greening is satisfied.

Description

technical field [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...
