A method for rapid cultivation of large-leaf hydrangea container seedlings

Abstract

The invention provides a method for quickly cultivating large-leaf hydrangea container seedlings, which comprises the following steps: 1) selecting healthy and disease-free large-leaf hydrangea seedlings, cutting new shoots, removing leaves, leaving some petioles, and cleaning them for later use; 2) ) On the ultra-clean workbench, the branches are soaked and disinfected with alcohol solution and mercuric solution successively and rinsed; 3) The branches are cut into small sections, inserted into the starting medium and placed in the cultivation room for cultivation; 4) After cultivating for a period of time , the axillary buds germinated, cut off and inserted into the proliferation medium for culture; 5) After cultivating for a period of time, a small amount of callus tissue was formed at the base, and adventitious buds were formed. From the callus, the plants were divided into several clusters, and clustered seedlings were inserted Cultivate in the induction medium, further induce adventitious buds and rooting, form multi-branched rooted seedlings, and place them in the greenhouse for domestication; 6) After domestication for a period of time, clean the seedlings, and harden the seedlings in a full-light spray greenhouse; 7) Harden the seedlings After completion, plant in a 1-gallon container for the next step of cultivation to form a full-bodied container seedling product. The method for quickly cultivating large-leaf hydrangea container seedlings of the present invention saves the process of pinching the heart, has a short cultivation period, does not affect the flowering of the next year, has high consistency, and has a full plant type, and is suitable for large-scale container seedlings of large-leaf hydrangea and factories. Anniversary production.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for rapid cultivation of large-leaf hydrangea container seedlings. Background technique [0002] Macrophylla belongs to Saxifragaceae (Saxifragaceae) Hydrangea (Hydrangea), also known as large-flowered hydrangea, is a deciduous shrub with a flowering period from May to July. Its inflorescences are huge and colorful, including white and blue. , pink and purple, etc., are the most important materials for garden greening, potted plants, fresh cut flowers and dried flowers. Big-leaf hydrangea blooms from terminal buds, and the number of branches determines the flower volume. Therefore, the number of branches is an important basis for judging the product specifications and quality of big-leaf hydrangea. The breeding of big-leaf hydrangea is mainly based on cuttings. After the cuttings take root, the seedlings need to go through more than two toppings to meet the re...
