Abstract

The invention provides a method for culturing a cutting seedling of phoebe zhennan. The method comprises the following steps: selecting a cutting shoot of the phoebe zhennan for cutting and watering,spraying an acidic foliar fertilizer every 15-20 days, stopping fertilization when new bud branches and leaves grow to 5-6 cm, and diluting GENDUODUO rooting agent and then irrigating the roots every15-20 days; after the main root of the cutting seedling of the phoebe zhennan is lignified and fibrous roots grow to 1 cm or above, completely prying out root hairs and cutting off overlong main roots, clamping one third of the lower part of the root system by using a seedling planting device, then planting the cutting seedling of the phoebe zhennan in a container bag filled with a transplanting matrix, compacting the surrounding matrix, and then watering the cutting seedling of the phoebe zhennan thoroughly; and transferring the watered cutting seedling of the phoebe zhennan into a sunshade arched shed, and after transferring for 20 days, diluting 300-500 times of the GENDUODUO rooting agent with water every 15-20 days, and irrigating the roots. According to the method provided by the invention, an acidic environment required for growth is provided for the cutting seedling, extension of the root system can be ensured, the plant height is controlled, the survival rate is high, and theproblems of low survival rate, easiness in dehydration and high cost of the cutting seedling of the phoebe zhennan are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of zhennan planting, and in particular relates to a method for cultivating zhennan cutting seedlings. Background technique [0002] Zhennan (Phoebe zhennan) is an evergreen tree belonging to Lauraceae (lauraceae). Widely used, it is the one with the highest economic value in the genus Phoebe, and it is also a famous garden ornamental and urban greening tree species. Phoebe zhennan is naturally distributed in Guizhou, Sichuan, Chongqing, Hubei and other regions of my country. It is the main tree species that compose evergreen broad-leaved forests, and there are many excellent adult trees with fast growth and good stem shape. [0003] However, the tissue culture technology is immature at present, while the cutting seedling raising technology tends to be mature. Most of the research focuses on how to improve the rooting rate of cuttings. The rooting seedlings of cuttings are usually cut in the cutting pool, wh...
