The latest Culture method of Magnolia

Purple magnolia is a plant endemic to China, also known as magnolia, magnolia, wood pen, etc., the famous early spring ornamental flowers, Magnolia deciduous shrubs, full of purplish red flowers in early spring, elegant posture, unique amorous feelings, suitable for planting in front and back of the classical garden, can also be planted alone or scattered in a small courtyard, let's take a look at the breeding methods of Magnolia!

Growth habits of Magnolia lanceolata

Purple Magnolia is produced in Fujian, Hubei, Sichuan and northwestern Yunnan, and is a traditional flower in China for more than 2000 years. It is born on the forest edge of hillside at an altitude of 300m to 1600m. It has been cultivated in major cities and has been introduced to cities in Europe and the United States. It is light-loving, cold-resistant and can survive the winter in open ground. Love high dryness, avoid low dampness, waterlogging is easy to rot roots. Like fat and beautiful, excellent drainage and slightly acidic sandy soil, can also grow on weakly alkaline soil.

Propagation methods of Magnolia mandshurica

1. Sowing and propagation: the seeds of Magnolia Magnolia were sowed with picking after maturation from September to October, soaked in warm water of about 50 ℃ before sowing, sowed in ditches and sowed, and fertile sandy soil was selected for seedling cultivation. After sowing, the soil was covered with 2 cm soil, watered thoroughly, covered with grass, and often kept moist. Generally, the seedlings could emerge after about 2 months, and the soil could be divided after thawing in the following spring.

2. Grafting propagation: Magnolia seedlings of 2 ~ 3 years old should be selected as rootstock, bud grafting should be carried out from July to August, and cutting should be carried out in autumn. After cutting, the scion should be covered with soil, and the soil should be removed in the late spring of the next year. It can also be cut and grafted in the greenhouse, and then stored in wet sand. After the graft is healed, it will be transplanted before germination in the following spring.

3. Cuttage propagation: before cutting, the cuttings are stained with rooting powder or soaked in 25ppm's Tsai acetic acid solution for 20 hours, which can promote rooting and improve the survival rate. The cuttings are collected from the 1-year-old branches on the mother plant of Magnolia magnolia. The cuttings are 15 cm long and 2 leaves are retained at the upper end.

4. Ordinary pressing: the ordinary pressing is best carried out in February to March, cut the base of the branch to be taken into half the depth, cut a section upward, and then stick a tile in the middle, then gently press it into the soil without breaking it, insert it into the soil with "U"-shaped thick iron wire, fix it to prevent it from warping, and then pile it on the soil, and the spring pressing can be cut off and planted after sending out root buds.

5. High branch pressing: select strong and disease-free twigs (1.5 cm in diameter) on the mother plant before volley, cut the cracks in the lower part of the basin fork, then cover them with bamboo tubes or bottomless tile pots, fill them with culture soil, tie them tightly with string on the outside, be careful not to touch them, often spray a small amount of water, keep them moist, and grow new roots around May of the following year.

Culture methods of Magnolia mandshurica

1. Potted soil: Magnolia prefers loose and fertile acidic and slightly acidic soil, which can be cultivated by the same amount of rotten leaf soil and vegetable garden soil. The basin should be a little deeper and bigger, and some hard plastic foam blocks should be put at the bottom of the basin to enhance air permeability and drainage and prevent rotting roots. Turn the pot and change the soil once a year or every other year after flowering, keeping the persistent soil from 1x2 to 1x3.

2. Fertilization: Magnolia likes fertilizer. Fertilization should seize the two key opportunities of February before flowering and May after flowering. Nitrogen, phosphorus and potassium compound fertilizer should be applied once every ten days. The former makes buds expand and flowers bloom, while the latter promotes more pregnant buds and more flowers in the next spring. When the leaves fall in winter, the fertilizer mainly composed of phosphorus and potassium is applied once to enhance its cold resistance and overwintering ability.

3. Light and temperature: purple magnolia likes warm, humid and sunny environment, and is more resistant to cold. It is placed in sunny courtyards and rooftop gardens, where the sun grows vigorously and luxuriantly. Although it can grow under semi-shady conditions, it is thinner and has fewer flowers, while if it is too shady, it has no flowers. More hardy, Beijing and its southern areas can survive the winter outdoors.

4. Water and fertilizer: Magnolia likes to be moist and afraid of waterlogging, so timely and appropriate watering is very important. The Beginning of Spring to flowering, pot soil to keep moist but not wet, after flowering to keep moist but not waterlogged, after defoliation to keep slightly moist but not dry. Do not be dry or waterlogging at any time, especially in the rainy season.

5. Pruning: the root of Magnolia mandshurica has strong sprouting and tillering ability. if there is no need for reproduction, cut along with the growth and keep 3 trunk in each pot. For the branches that are too high and too long, they can be cut short just after flowering, and the healing ability is poor. After cutting, they should be coated with sulfur powder for anticorrosion. If it is not necessary, they should not be cut. If there is no need to leave seeds for reproduction after flowering, the residual flowers should be cut off with pedicels.
