Cutting and seedling raising method for hydrangea macrophylla

Abstract

The invention belongs to the technical field of planting, and discloses a cutting and seedling raising method for hydrangea macrophylla. The method comprises the steps of (1) planting a hydrangea macrophylla maternal plant in a cultivation matrix, spraying a nutrient solution, and timely watering; (2) picking cutting slips after the hydrangea macrophylla maternal plant grows for 10-20 days in thecultivation matrix, and cutting the cutting slips into cutting branches with the length being 3-5cm; (3) placing a cutting matrix in a 72-hole tray, soaking the cutting branches in a rooting solutionfor 1-3min, then cutting the cutting branches into the cutting matrix, profoundly watering immediately, profoundly spraying the cutting slips with carbendazim, placing the cutting slips in a greenhouse, setting a sunshade above the seedbed for shading, spraying water timely, spraying a foliar fertilizer 10 days after cutting, and then spraying the foliar fertilizer every 10-15 days after wateringuntil obtaining rooted hydrangea macrophylla seedlings. The cutting and seedling raising method is simple to operate and high in propagation speed, the survival rate of hydrangea macrophylla cutting propagation reaches up to 98% or above, and the cutting and seedling raising method can be applied to large-scale production.

Description

technical field [0001] The invention relates to the technical field of hydrangea planting, in particular to a hydrangea cutting seedling raising method. Background technique [0002] Hydrangea, also known as hydrangea and hydrangea, is a plant of the genus Hydrangea in the saxifrage family. Hydrangea flowers are white and plump, large and beautiful, and its flower color can be red or blue. It is a common potted ornamental flower and tree. Huge in shape, bright in color, long in flowering period, large and shiny in leaves, both flowers and leaves are appreciable. In Europe, the Netherlands, Germany and France are more commonly cultivated. The provinces in the Yangtze River Basin of my country are generally planted in the open field, and there are many greenhouse potted plants in the north. Hydrangea is an ideal flower and tree suitable for both garden cultivation and potted ornamental. Its potted plants can be used to decorate exhibition rooms and halls. Because of its ric...

Problems solved by technology

[0003] Most of the traditional hydrangea propagation methods use cuttings to reproduce, while the ear-picking mother plants are generally cultivated in pastoral soil. The mother plants grow slowly and are susceptible to diseases. However, the traditional cutting substrate has a single function and poor water and fertilizer retention. It is difficult to control, the slow seedling period after transplanting the cutting seedlings is long, and the pastoral soil is easy to cause the roots to rot. Therefore, the survival rate of traditional cuttings is not only low, but also the cost of raising seedlings is high
