Tilia miqueliana layerage propagation method

Abstract

The invention belongs to the technical field of propagation of plant seeds and seedlings, and discloses a tilia miqueliana layerage propagation method. The tilia miqueliana layerage propagation methodcomprises the following steps of A, performing female parent selection and culture; B, performing layerage selection and treatment; C, performing layerage substrate selection and treatment; D, executing a layerage method; and E, performing layerage seedling transplanting and fertilizing management. The tilia miqueliana layerage propagation method disclosed by the invention is simple to operate, tilia miqueliana seedlings can be cultivated in a large scale, massive female parents can be used for sprouting tillers and branches, and cost is reduced for seedling culture. The rooting time of layerage is 55d, the survival rate is 90% or above, the vacancy of tilia miqueliana market resources is effectively filled, and the application prospects are great.

Description

technical field [0001] The invention relates to a Nanjing linden bead rapid propagation method, and belongs to the technical field of woody plant seedling propagation. Background technique [0002] 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. Nanjing linden has been positioned as a key development landscape tree species and afforestation tree species as early as in the forestry development plan of our province and the "Jiangsu Province Forest Tree Seedling Development Plan (2008-2015)", and it is also the "Nanjing Green Space System Planning" (2013~2020) ) and "Nanjing Street Tree Species Planning" (2014) proposed to focus on the promotion and application of garden native tree species, and it is also one of the 10 priority recommended precious tree species in the "Jiangsu Province Precious T...

AI Technical Summary

Problems solved by technology

Although there are currently some studies on Nanjing Tilia rapid propagation technology, most of them focus on cutting propagation. During the cutting process, the cuttings are separated from the parent body, and the humidity and temperature of the environment must be controlled to improve the survival rate. It is difficult and the seedling production Can not be effectively guaranteed, which largely limits the development of Nanjing Tilia seedling industry

Therefore, at present, the number of seedlings of this tree is very small in China. 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".
