Problems solved by technology

Although there are currently some studies on the rapid propagation technology of Nanjing Tilia cuttings, it is difficult to control the humidity and temperature during the cutting process, and the seedling production cannot be effectively guaranteed, which largely limits the health and sustainability of the Nanjing Tilia seedling industry. The development has directly affected the popularization and application of Nanjing Tilia
Therefore, the number of seedlings of this species is very small in China at present. Relevant studies have shown that it is difficult for the seeds of Nanjing Tilia to germinate, so resources are very scarce, and the application is also "out of stock".

Embodiment Construction

[0039] A method for facility-based high-efficiency cutting Nanjing linden is characterized in that it comprises the following steps:

[0040] A) Female parent selection and cultivation; B) Cutting facility construction; C) Cutting substrate selection and treatment; D) Cutting selection and treatment; E) Cutting method; F) Cutting seedling transplanting and fertilization management.

[0041] In November 2015, the female parent selected 2-year-old seedlings, and re-cut the female parent of Nanjing Tilia fringe, and pruned at the base of the main trunk to keep 2-3 axillary buds.

[0042] The female parent culture method in step A) is: container cultivation, the perlite of culture substrate selection volume ratio 1:1:1: peat soil: yellow core soil, base fertilizer is to add the organic slow-release fertilizer of weight fraction 10% in the substrate; 2016 March Before the shoots germinate in the month, put the ear-picking female parent in the greenhouse or seedling greenhouse for g...

Abstract

The invention belongs to the technical field of plant seedling propagation, and discloses a method for installation efficiently cutting tilia miqucliana. The method comprises the following steps of A, selecting and cultivating a female parent; B, building a cutting cultivation room; C, selecting and treating a cutting medium; D, selecting and treating cutting slips; E, cutting; F, transplanting, fertilizing and managing cutting seedlings. According to the method for installation efficiently cutting the tilia miqucliana provided by the invention, the rootage duration of the tilia miqucliana can be greatly shortened to 15d, the survival rate of cutting is 95 percent or more, and 12 times of cutting can be carried out one year, so that the problem of market resource vacancy of the tilia miqucliana is effectively solved, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of seedling propagation of woody plants, and in particular relates to a facility-based cutting method for Nanjing linden. Background technique [0002] With the development of the modernization of agriculture and forestry, tree growth as one of the important industries has broad prospects for development, Nanjing Tilia ( Tilia miqueliana ) is a deciduous tree with a height of 20 meters. It is a "native tree species" in Jiangsu Province. It is an excellent tree species integrating timber species, honey plants and garden ornamentals. However, due to the difficulty in propagating this tree species, its popularization and application has been greatly restricted, resulting in its failure to be effectively promoted today. [0003] Cutting, grafting, and tissue culture are common asexual propagation methods in the art. Cutting, also known as cuttings, is a common propagation method for cultivating plants. The ste...
