[grafting method of Azalea] how to graft Azalea

Azaleas in decorating the home environment can play an important role, on the one hand to bring visual enjoyment, on the other hand can clean the air. Let's talk about the grafting method of Azalea and the maintenance of Azalea.

1. Grafting method of Azalea

1) wiping head splicing. When the branches of the rootstock only have several rounds of leaves at the top and there are no leaves in the middle and lower parts, this grafting method should be adopted. First cut off the tip of the leafy branch, and then cut a gap 0.6 cm deep in the middle of the cut. The scion should pick the shoot with the top leaf and cut the base to 0. 5 cm long duckbill-shaped, inserted into the rootstock incision, so that one side of the cambium aligned and ligated.

2) keep the head and abdomen. On the branches of the rootstock, there are not only leaves around the growing point, but also leaves in the middle and lower parts, so this method should be used for grafting. Do not cut short the rootstock, but cut an oblique opening 0.5 cm long under the middle of it, and do not exceed the diameter of the branch Ibig 2, and tie up the duck-billed face at the base of the scion.

Azaleas are evergreen flowers and trees, and the scion is fresh and tender with leaves, which must be protected by plastic film after grafting to prevent the leaves from withering. The temperature in the cover should not exceed 30 ℃, the humidity should be maintained above 80%, shade maintenance, most of them can heal after 20 days, and then remove the film after 30 days.

II. Matters needing attention in rhododendron culture

The main results are as follows: 1. After the rhododendron flower is faded, the residual flowers must be cut off to avoid fruiting and consuming nutrition. after the new branches germinate, they should be thinned properly and stay according to the growth of the plant.

2. Potted azaleas are generally placed on the southeast balcony and should be ventilated and move as little as possible. If it is not ventilated, it is easy to suffer from black spot disease and a large number of fallen leaves.

3. Timely thinning of buds and leaves, removing part of the buds and leaves that grow too much and too dense, so as to circulate the air and concentrate nutrients on the buds. After the formation of buds, it is necessary to increase nutrition and apply more phosphorus and potassium fertilizer, otherwise the buds will be transformed into leaf buds.

4. Excessive direct light in summer, frostbite, too much watering, too thick fertilization, too long indoor time, poor air circulation or dark and humid places, acid rain, etc., may lead to azaleas falling leaves or not blooming.

5. Turning the basin and changing the soil do not need to be carried out every year, usually once every 2 to 3 years, with as little damage to the roots as possible. The time should be after the flower fade or autumn, and topirazine should be sprayed at the same time to prevent diseases.

Third, the cultivation knack of rhododendron

Potted rhododendron varieties are Sihai wave, cold peony, crown, five pearls, peach (also known as Holland). Choose to use cuttings or high-pressure propagation of robust seedlings, it is appropriate to use mud basin. In the basin soil, humus soil under coniferous trees is mixed with a small amount of garden soil and sand, and then bone powder is added, or 4 parts of rotten leaf soil under broad-leaved trees, 4 parts of rotten barnyard manure and 2 parts of sand are mixed evenly, and appropriate amount of sulfur powder is added to make the soil acidic and apply basic fertilizer. the size of the basin should be appropriate to the size of the plant, the basin is too large to cause the soil to be too wet and rotten roots, and the bottom of the basin is covered with tiles to facilitate drainage. The seedlings should be compacted around the pot. After that, the immersion basin irrigation method is used to pour water through. Keep the basin soil moist during the growth period. It is best to store tap water in a tank for 1-2 days and place it in a ventilated and shaded place. Place the balcony in a ventilated and half-shaded place after 10-12 days.

Phosphorus and potassium fertilizer should be applied frequently (once a week) in autumn, and fresh water should be irrigated once the next day after fertilization. Stop fertilizing in winter and rainy season.

The above are the grafting methods of Azalea introduced in this paper, matters needing attention in rhododendron culture and cultivation tips. Hope to let you understand the breeding and breeding of azaleas, as well as the matters needing attention in the process of breeding, and cultivate an exuberant Azalea for yourself.
