Method for quickly culturing seedlings of ternstroemia gymnanthera

Abstract

The invention relates to a method for quickly culturing seedlings of ternstroemia gymnanthera. Common ternstroemia gymnanthera breeding methods include a seed propagation method and a cutting propagation method which have the problems of long seedling culturing time, small specifications of nursery stocks and the like. The method for quickly culturing seedlings, disclosed by the invention comprises the following steps of (1) in spring, spraying full trees with cytokinin; (2) in autumn, girdling side branches, wrapping cut positions with substrates mixed with No. 1 rooting powder so as to promote rooting, wherein the substrates mixed with the No. 1 rooting powder include components of sphagna and yellow mud, and the mass ratio of the sphagna to the yellow mud is (40-80%) to (20-60%); (3) in winter in the same year, cutting off layering branches, temporarily planting the layering branches into deep holes, and covering films for heat preservation and moisture preservation; and (4) in March in spring in the next year, digging out temporarily-planted seedlings, removing wrapped plastic films, transplanting the temporarily-planted seedlings without the plastic films into flower pots, and periodically watering the seedlings so that the seedlings can be shaped in the same year and the seedlings can be taken out of a nursery after four seasons. According to the method disclosed by the invention, the ternstroemia gymnanthera cultivating time can be effectively shortened, the operation is simple and convenient, the investment cost and the operation cost are low, and the method is suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the field of seedling cultivation methods; in particular, it relates to a rapid seedling cultivation method of thick skin fragrant. Background technique [0002] Ternstroemia gymnanthera (Ternstroemia gymnanthera), also known as pearl wood tree and wild daphne, belongs to the family Theaceae. Thick-skinned incense has regular branch sequence, luxuriant branches and leaves, beautiful tree shape, red petiole and new leaves. It is suitable to be planted in clusters on the edge of forests or beside walls and bamboo fences, and is widely used in landscaping. The common breeding methods of A. chinensis include seed propagation and cutting propagation. These two methods have problems such as long seedling time and small size of seedlings. Therefore, the research on rapid and efficient seedling raising technology on A. chinensis can greatly shorten the seedling time. Improve economic efficiency. Contents of the invention [0003] ...
