The cultivation method of Magnolia denudata_Family flower cultivation

Magnolia, also known as white orchid, yellow orchid, is an evergreen tree, Luzhou-scented flowers. Its green leaves, white flowers such as jade, fragrant Ruolan, long florescence, suitable environmental conditions, can blossom all the year round. But it is afraid of drought, waterlogging, cold and alkali, so it is regarded as a delicate and difficult flower in the north. Culture requirements:

First, it requires fertile, loose and well-drained cultivated soil. It 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 with poor permeability. The upper basin uses ventilated tile pots (plain burning pots), do not use glazed pots, porcelain pots, purple sand pots, etc., it is best to use deeper cylindrical flowerpots, buckle empty flowerpots under the pots, and erect them with bricks to prevent poor drainage; the bottom of the basin is paved with about 5 cm of slag and gravel.

Second, the moisture should be suitable. White orchid is a 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. Watering must be thoroughly watered, often half of the water will cause shallow roots. White orchids should not be watered in spring and autumn, they should be watered every day in midsummer and must be watered in the evening, and the amount of water should be reduced at the end of autumn and watered every 10 days in winter. The overcast and rainy season should be moved to shelter.

Third, be afraid of alkali. White orchid prefers acid soil, and the requirement of soil pH value is 5.56.3. In the northern region, white orchids are not easy to raise because most of the water and soil there are alkaline, which dissolves the protoplasm of white orchid cells, resulting in slow growth and poor growth of flowers. Often irrigated with fermented Amoy rice water, the effect is better.

Fourth, be afraid of thick fat. White orchids like phosphorus and potassium fertilizer, but avoid too high concentration, otherwise it will produce reverse osmosis and cause "physiological drought" of the plant, wilting lightly or burning to death. The fertilization principle of white orchid is: "sparse application, regular application, evening application". Practice has proved that using thin human feces, urine and bean cake water mixed with smashed fish offal, rotten shrimp, chicken viscera, etc., after retting, it is applied every 3-5 days according to the proportion of fertilizer and water at 1:9, and calcium sulfate is added when it is applied, the effect is better, and the fragrance of white orchid can be strong.

Others: pick leaves and hearts. My Magnolia Magnolia leaves the shed from the Spring Equinox to Qingming Festival and chooses cloudy or cloudy days. 3 days after leaving the room, let the potted flowers adapt to the outdoor environment, and then remove the old leaves, leaving only a few tender leaves, so that they can promote the development of new shoots. After each batch of flowers, a small number of old leaves should be removed to promote the growth of new branches and the formation of flower buds. During the growth period, it is necessary to often pick the heart, control the apical dominance, and promote multiple lateral branches.

The light is suitable, Magnolia is a positive flower, it needs plenty of sunlight, and it should be maintained on the sunny ground with long sunshine and strong light during the growth period, 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 the hot and hot "dog days" to moderate shade, 12-16:00 every day to avoid scorching sun exposure, but also to avoid brick walls or cement floor high-temperature radiation. At this time, it is not only necessary to spray water to the plant to cool down, but also to water the ground or spray water to cool and dissipate heat to increase the humidity of the air.
