Cuttage technology optimization-based high-efficient cultivation method for taxodium Zhongshanha container seedlings

Abstract

The invention discloses a cuttage technology optimization-based high-efficient cultivation method based on taxodium Zhongshanha container seedlings, and belongs to the technical field of taxodium Zhongshanha cuttage seedling raising. The method comprises the following steps: performing cuttage on taxodium zhongshanha cutting slips by adopting degradable non-woven fabric cuttage seedling raising bags in early June and middle June, and after cuttage is completed, putting cuttage seedlings into a shading shed for spraying management; and after 20-30 days, planting the cuttage seedlings and the cuttage seedling raising bags into a large-specification seedling raising container, and after 2-3 months of seedling refining management and later maintenance, obtaining high-quality taxodium zhongshanha container seedlings with the height being 50 cm or above in the current year. According to the method, seedling bag cuttage replaces a cuttage bed type cuttage method, so that the ventilation condition of a cutting rooting environment is improved, and rooting of cutting slips is promoted; and a one-bag and one-seedling mode is adopted, so that after cuttage seedlings root, containers can be replaced for planting in time, and damage to root systems of the cuttage seedlings cannot be caused.

Description

technical field [0001] The invention belongs to the technical field of cutting seedling cultivation of Zhongshan fir, and in particular relates to a method for efficiently cultivating container seedlings of Zhongshan fir based on cutting technology optimization. Background technique [0002] Zhongshan fir is the collective name for the excellent hybrid clones of the genus Baldox. The Institute of Botany, Chinese Academy of Sciences, Jiangsu Province has been introducing and hybridizing the trees of the genus Baldactyl since 1973. Up to now, it has obtained 8 national new plant variety rights, There are 10 national and provincial forest tree varieties. The "Zhongshan Shanshan 302" and "Zhongshan Shanshan 401" promotion projects were selected by the Ministry of Forestry as one of the 100 national forestry science and technology promotion achievements in 1997. Zhongshan fir has the advantages of fast growth, water and humidity resistance, salt-alkali resistance, good material,...

Problems solved by technology

In order to ensure the emergence rate in production, the traditional cutting method of bed-type cuttings generally has about 500 cuttings per square meter, and some production companies even have a higher cutting density of 700 or more. This method uses high-density cuttings and centralized management. To a certain extent, the cost of seedling breeding has been reduced, and the seedling output per unit area of ​​the facility has been increased. However, due to the use of high-density cuttings, there are often problems such as uneven quality of cutting seedlings, susceptibility to diseases during bed retention, and growth efficiency. Low, large root damage when raising seedlings, etc.
