Rapid cultivation method for hydrangea macrophylla container seedlings

Abstract

The invention provides a rapid cultivation method for hydrangea macrophylla container seedlings. The method includes the steps of: 1) selecting healthy and robustly growing and disease-free hydrangeamacrophylla seedlings, scissoring newly growing branches, removing leaves, retaining parts of petioles, and performing cleaning for standby use; 2) conducting immersion disinfection on the branches with an alcohol solution and a mercuric chloride solution in order on a super clean workbench, and rinsing the branches clean; 3) cutting the branches into small pieces, inoculating the small pieces ofbranches into a medium, and conducting culture in a culture room; 4) after culturing for a period of time, sprouting axillary buds, cutting off the sprout tender branches, and inoculating the branchesinto a proliferation medium for culture; 5) after culture for a period of time, forming a small amount of calluses and adventitious buds at the root, dividing the plants into several clusters, inoculating the plants into a clustered seedling induction medium for culture, further inducing adventitious buds and rooting to form multi-branch rooting seedlings, and putting the seedlings in a greenhouse for acclimatization; 6) after acclimatization for a period of time, cleaning the seedlings, and conducting seedling hardening in a full-illumination spray greenhouse; and 7) at the end of seedling hardening, planting the seedlings in a 1 gallon container for next-step cultivation, thus forming a full-plant container seedling product. The rapid cultivation method for hydrangea macrophylla container seedlings provided by the invention eliminates the pinching process, has short cultivation period, does not affect the flowering of the next year, has high consistency, and can achieve full plants,and is suitable for large-scale and factory anniversary production of hydrangea macrophylla container seedlings.

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...
