[Michelia] how to grow Michelia

Michelia mollissima is a famous flower and foliage plant, which is generally planted in the courtyard at home, while some people choose small varieties of Michelia to plant in the living room, window, and other places. Michelia blossoms are filled with fragrance, giving people a very comfortable feeling. Today let's learn how to grow Michelia flowers:

First, how to raise Michelia flowers

Potted plants with Michelia mollissima should be changed before the new leaves grow after flowering in spring every year to meet the nutritional needs of their growth and development; they should be placed in a well-ventilated semi-shady place, and the mud must be loose and breathable and well drained. Michelia has many roots and is fleshy. If it is watered too much or waterlogged after rain, it will cause root rot and even death caused by diseases and insect pests. Fertilization should be fully mature, if possible, it is best to cooperate with phosphorus and potassium fertilizer. Base fertilizer is applied before new buds germinate every year, and dilute fertilizer is applied every other month thereafter. Before leaving the room in March every year, the dead and diseased branches should be cut off; after the new branches grow, they should also be properly cut where they are too dense to facilitate growth.

In addition to sowing and grafting, the propagation method of Michelia mollissima usually adopts the method of cutting and pressing. Autumn planting takes place in mid-September and spring planting takes place in late March. Cut in the open field, choose one-or two-year-old branches, cut them into about half a foot, and take root in a month and a half. Autumn cuttings are usually put into pot in March of the following year, while spring cuttings are usually put into pot in September.

Michelia in the room meat winter, due to high temperature, not ventilated, prone to shell insects, and suffer from soot disease, must be timely prevention and control.

II. Matters needing attention in the cultivation of Michelia mollissima

1. Temperature: the lowest temperature of Michelia mollissima overwintering is not less than 5 ℃. Once the temperature is lower than 5 ℃, the normal physiological activity of the plant will be affected, the absorption capacity of the root will be weakened, and the twigs and leaves of the plant will wilt. At the same time, the highest temperature should not exceed 15 ℃. If the temperature is too high, too much nutrients are consumed in the plant, which is disadvantageous to the growth of the next year. Therefore, it is suitable to keep the room temperature at 5 ℃ to 15 ℃ in winter.

2. Fertilization: Michelia likes fertilizer, and retting fertilizer such as rotten cake fertilizer, bone meal, chicken and duck manure and fish belly intestines are often mixed with water. Fertilizer is applied every 15 days in the growing season (from April to September), and fertilizer is stopped after flowering and October. If you find that the leaf color is not bright and thick green, you can apply fertilizer and water for once.

3, insect pests: Michelia often occurs shell insect damage, but also can induce soot disease, shell insects can be brushed off with a small brush, or with 150 times the water of the No. 20 petroleum emulsion spray: soot disease can be scrubbed with clean water or sprayed with 500 times water and 1000 times carbendazim aqueous solution.

4. Pruning: Michelia flowers should not be overpruned. Usually, the overgrown branches, weak branches and overdense overlapping branches that affect the shape of the tree can be pruned after flowering, and the fruit after flowering can be subtracted to reduce nutrient consumption. Before sprouting in spring, remove some old leaves properly to trigger new branches and leaves.

Third, the breeding method of Michelia mollissima:

1. The method of grafting breeding of Michelia mollissima

Michelia mollissima grafting propagation, often with purple magnolia, Tianmu magnolia as rootstocks for branch grafting, but also easy to survive. The time of grafting should be from late March to early April before the germination of Michelia mollissima. Autumn pickup should be from late September to early October. The seedlings of autumn grafting should be strengthened, the management of spring grafting is easy, and the survival rate of grafting can generally reach 85%. The grafting method is generally adopted, and the strong annual branches in the middle and upper parts of the mother tree are selected as scions, which grow 1 / 2 nodes without leaves. The operation technique is in accordance with the general cutting routine. After cutting, in order to prevent water from soaking into the wound, it is necessary to cover the straw and expose the top tip. After about 25 days, the scion can heal and begin to sprout, then remove the cover grass and wipe off the sprouting on the rootstock in time.

2. The insertion breeding method of Michelia mollissima

The cutting propagation of Michelia mollissima can reproduce more plants in a short period of time, but the growth is slower than that of grafted seedlings. Spring and summer are the appropriate time for insertion. Spring insertion is carried out in late March, selecting 1-2-year-old branches and shoots with a length of 10 mi 15 cm, cutting off the lower leaves and inserting them into a seedbed with loess mixed with river sand (6:4) as the substrate. After insertion, shade is required (about 30% light transmittance), and the bed surface is often kept moist. Planting in the basin after rooting. The summer insert selects the semi-lignified branches of the same year, which are about 8 meters long, the method is the same as that of spring planting. It should be noted that the summer temperature is high, the air humidity is high, and there are conditions for the breeding of various diseases. Therefore, the intercalated matrix must be disinfected. In addition, if the base of the cuttings can be soaked in indolebutyric acid of 200ppm for 15 minutes, and then dried, the hairy roots can be accelerated and the survival rate can be improved.

The branches and branches of Michelia are elegant, and when they bloom, they think of charming flowers. They are well-known varieties of foliage and flowers. It is very appropriate to beautify the living room. Through the breeding method of Michelia flowers, the maintenance is relatively simple. If you like Michelia flowers, you might as well decorate in the living room and other places.
