Cuttage propagation method for Ailanthus altissima

Abstract

The invention discloses a cuttage propagation method for Ailanthus altissima. The method comprises the following steps: collecting cuttage cuttings; preparing cuttage seedling beds, wherein a substrate of the seedling beds is prepared from peat, mushroom cultured residues, mulberry twig powder and vermiculite which are in the weight ratio of 10: (2 to 3): (3 to 4): (2 to 4), and the substrate is firstly subjected to spraying disinfection by a 0.2% potassium permanganate solution and then is loaded to seedling raising cups; subjecting the cuttings to soaking disinfection by a 0.2% potassium permanganate solution, then, soaking the cuttings in an ABT rooting solution with the concentration of 200mg / L, so as to obtain treated cuttings; inserting the treated cuttings into the seedling raising cups in a cuttage manner in accordance with that the depth of each cutting inserted into the substrate is 3cm to 4cm, and then, drenching the substrate with water; and after cuttage, carrying out cuttage management and seedling hardening and transplanting, thereby obtaining Ailanthus altissima seedlings. After carrying out cuttage cultivation for 20 to 25 days by the method disclosed by the invention, the rooting rate reaches 90% or more, and the survival rate of cuttage can reach 90%. The method disclosed by the invention has the advantages of simplicity in operation, low cost, high propagation speed and high survival rate, can be used for rapidly obtaining a large number of Ailanthus altissima seedlings and has a very good popularization value.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a method for cutting and multiplying Ailanthus ailanthus. Background technique [0002] Ailanthus altissima tree (Ailanthus altissima) belongs to Ailanthus family and Ailanthus genus, also known as Ailanthus bark and Ailanthus altissima. Distributed in China, from Guangdong, Guangxi, and Yunnan in the south to southern Liaoning in the north, across 22 provinces and regions. It has strong smoke resistance and is a good tree species for greening in industrial and mining areas; because of its strong adaptability and strong sprouting ability, it is a pioneer tree species for mountain afforestation, and it is also a tree species for water and soil conservation and soil improvement in saline-alkali land. Because the Ailanthus ailanthus tree has great application value, the market demand is increasing year by year, and the price increases accordingly. Since the wild Ailanthus tr...

Problems solved by technology

Cutting propagation can maintain the characteristics of the variety, and the cultivated plants grow faster than sowing seedlings, and can be cultivated into large seedlings in a short time, but the cutting seedlings obtained by cutting propagation have poor root systems and cannot form taproots. The survival rate of seedlings is low, and the life span is longer than that of sowing. Seedlings are short and less resistant to stress

At present, there are few studies on the cutting propagation of Ailanthus ailanthus tree, and the existing cutting propagation methods of Ailanthus ailanthus tree have problems such as long seedling cultivation period, unstable rooting rate, less root system of cutting seedlings, weak disease resistance, etc., resulting in the survival rate of seedlings after planting Low and slow growth rate, not conducive to large-scale production of Ailanthus tree cuttings
