Planting methods of Magnolia

Magnolia, also known as Magnolia Magnolia, comes from the flowers of Magnolia in Magnoliaceae. There is another kind of magnolia, which has large flowers and can be used as a street tree for viewing. The petals of magnolia are white or purple striped. Magnolia is one of the most valuable flowers and trees in China, and it has been loved by people since ancient times.

1. Soil: White orchid likes acidic soil, and the requirement of soil pH value is 5.5-6.3. it is best to use fertile, loose and well-drained soil. TV can be prepared with 5 parts of pine needle rotten leaf soil, 2 parts of crude bran ash, 2 parts of coarse sand and 1 part of retted barnyard manure, and do not use fine sand or clay heavy soil with poor air permeability.

2. Sunshine: Magnolia magnolia is a positive flower, which needs plenty of sunlight and should be maintained on sunny ground with long sunshine and strong light during growth, especially during flowering. The light should not be less than 6 hours a day. If it is maintained in a shaded place, it will only grow leaves but not blossom, or blossom very little, the branches are slender, the leaves are light, and the leaves are thin and dull, which is disadvantageous to the growth. But in summer to avoid direct sunlight, 9 am to 4 pm to give shade, at the same time to spray water on the leaf and the ground to increase air humidity.

The growth of Magnolia needs to receive sufficient light, the growing period should be placed on the balcony or other sunny places with long sunshine and strong light, pay more attention to the maintenance of light during flowering, and ensure more than 6 hours of light every day. Long-term maintenance in the shade is not conducive to the normal flowering of Magnolia. Only in the "dog days" where the strong light is directed for a long time, it is usually between 12 and 16:00 every day. At this time, the ground temperature should also be cooled, the specific method is to spray cold water to the ground, but also increase the humidity of the air, artificial to create a suitable environment for the growth of Magnolia.

3. Temperature: White orchids like to be warm and afraid of cold, so special attention should be paid to protection to make them safe to survive the winter. It is generally moved into the room in late October and placed in the sunny place. it is better to keep about 10 ℃ at room temperature, not less than 5 ℃.

4. Watering: White orchid belongs to fleshy root, the potted soil is too wet, the leaves will wither and fall off, and even the rotten roots will die, and if they are too dry, they will wither and curl their leaves. They are flowers that are afraid of both waterlogging and drought. During the flowering period, when the petals are too open, it shows that the water is insufficient, and the suitable moisture is in the shape of a bud; the surface of the basin soil is dry, and the soil should be watered immediately when the soil is hard and cracked. Watering requires that the water temperature and soil temperature must be the same, and can not suddenly pour cold or hot water. Spring and autumn generally can be watered once a day, hot summer, large evaporation, exuberant growth, can appropriately increase the number of watering and weight. When moving indoors in winter, you should refrain from watering.

Therefore, watering should be carried out every day from early summer to late autumn to keep the soil moderately moist, especially in the dry "dog days" in the morning and evening, and the air humidity should also be improved by spraying leaves and flowerpots. If tap water is used for watering, the soil should be prevented from being alkalized. If leaves are yellowed, ferrous sulfate or 0.7% concentration of acid and vinegar water should be applied to water the roots in time.

5. Fertilization: White orchid flowers have a long flowering period and like fertilizer, but if there is not enough fertilizer, they will blossom less. Inappropriate fertilization will lead to excessive growth of branches and leaves and poor flowering. Before the germination of new buds from February to March, mature cake fertilizer was used as base fertilizer. , apply thin human feces and urine during flowering, or apply 9 parts of fermented liquid fertilizer from bean cake, tea seed cake and fish bones to water, once every 3-4 days. Stop fertilizing half a month before entering the house for the winter.

Magnolia needs more nutrients for its growth because of its long flowering period, large flower shape and large number of flowers. Appropriate fertilization is needed to provide sufficient nutrients for its growth, so as to ensure that Magnolia can blossom luxuriantly and beautifully when the normal flowering time comes. When potting, you should apply enough base fertilizer, and fertilize organic liquid fertilizer (rotten cake fertilizer and water) every 5-7 days during the flowering period from May to July. To adhere to the principle of "frequent application of thin fertilizer", fertilizer can be prepared first light and then thick, do not apply raw fertilizer, so as to avoid root burning. In addition, extra-root fertilization should be taken every 7-10 days, and 0.5% concentration of plant oxytocin and 0.3% concentration of potassium dihydrogen phosphate can be sprayed.

6. Pruning: during the growth of white orchid, the plant should be pruned, the diseased branches and overgrown branches should be cut off, and part of the lower leaves should be removed so as to inhibit plant growth and promote more flowering of pregnant buds. Magnolia branch wound healing ability is poor, so generally do not prune. However, for the sake of reasonable tree shape, the overgrown branches, withered branches, disease and insect branches and branches that hinder the beauty of the tree shape should still be cut off at the initial stage of leaf expansion. In addition, after the flower fade, if there is no seed, the remnant flower and the ear of oyster should be cut off so as not to consume nutrients and affect the flowering in the coming year.

Magnolia is fresh and elegant, is an important garden beautification plant, in Magnolia culture should pay attention to:

Magnolia is a flowering tree species with early spring color and fragrance. When planting, it is necessary to grasp the right time, neither too early nor too late. It is most suitable to plant Magnolia 10 days before germination in early spring or before spreading leaves after flower fade. When transplanting, regardless of the size of the seedlings, the roots should carry mud clumps and be careful not to damage the roots as far as possible. To ensure survival. Before planting, fully mature organic fertilizer should be applied in the hole as base fertilizer. After planting, seal the soil and press it, and pour enough water in time.

The root system of Magnolia is fleshy and can not tolerate stagnant water. It is advisable to keep the soil moist during the flowering and growing period. After entering the autumn, we should reduce watering, delay the rooting of magnolia, and promote the branches to mature in order to survive the winter. It is generally not watered in winter, but only once when the soil is too dry.

Magnolia prefers fertilizer, but avoids big fertilizer; generally applying fertilizer twice during the growing period can be beneficial to flower bud differentiation and promote growth. Once in early spring, and again in May-June. Fertilizers are often made of fully mature organic manure. Newly planted seedlings do not need to be fertilized until after falling leaves or in the following spring.
