Problems solved by technology

However, in the process of cutting and cultivating rhododendrons, the cutting branches of rhododendrons have special requirements on the substrate and growth environment, and they are easy to be infected with germs and suffer from insect pests during the seedling cultivation process. low, which also brings great difficulty to large-scale rhododendron cutting cultivation and increases the cost of rhododendron cutting cultivation

Embodiment 1

[0028] A cutting cultivation method for increasing the rooting rate of rhododendrons. Select 10cm semi-lignified branches of rhododendrons in the same year, and then cut the obtained branches after pretreatment, and cultivate them under daily management until they grow into seedlings. The specific steps of the pretreatment In order to remove the excess leaves from the obtained branches, leave the top 2 leaves, then put them into the disinfectant for 0.5h, remove and drain the liquid on the surface, and then insert the lower part of the branch with 20% of the length into the nutrient solution for 16 hours. Scoop out the liquid that drains off the surface;

[0029] The disinfectant is composed of 1 part of isoquercitrin, 1 part of catarrhine, 1 part of shikonin, 1 part of isopulegol, 2 parts of chlorogenic acid, 2 parts of gibberellins and 40 parts in parts by weight. It is formed by mixing boric acid with a mass concentration of 0.3%;

Abstract

The invention discloses a cutting cultivation method for improving the rooting rate of azalea. A semi-lignified azalea branch with the length of 10-15cm which is generated in the current year is selected, the obtained branch is pretreated and then subjected to cutting, and daily management is performed until seedling is bred, wherein the pre-treatment comprises the following specific steps: redundant leaves are removed from the obtained branch, and 2-3 leaves at the top end of the branch are reserved, and then the branch is soaked in a disinfectant for 0.5-2.5 hours and then fished out and the liquid on the surface of the branch is drained, the lower end part of the branch with the length of 20%-40% of the whole length of the branch is inserted into a nutrient solution and soaked for 16-20 hours, the branch is fished out and then the liquid on the surface of the branch is drained. The cutting cultivation method is time-saving, labor-saving and low in cost, batch process is easily performed, and the rooting rate and the survival rate of the azalea cutting branches are greatly improved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cutting cultivation method for increasing the rooting rate of azaleas. Background technique [0002] Rhododendron, also known as azalea and pomegranate, is an evergreen or ordinary green shrub. Rhododendron generally blooms in spring, with 2-6 flowers per cluster, funnel-shaped corolla, red, light red, apricot red, snow green, white, etc., with luxuriant and bright colors. It is a typical acid soil indicator plant in south-central and southwest China. The whole rhododendron can be used for medicinal purposes. It has the effects of promoting qi and blood circulation and nourishing deficiency. It can treat internal injury cough, kidney deficiency and deafness, irregular menstruation, rheumatism and other diseases. Because of its bright red corolla, it is a famous flower plant with high ornamental value. [0003] Rhododendron can be propagated by five methods: cutting,...
