How to plant Damu orchid seed

Damu orchid, also known as magnolia, is suitable for indoor cultivation, and very beautiful, as well as noble gentleman style, so how to grow magnolia seeds?

I. preparation of basin soil

Damu orchid is a fleshy root, which requires loose, fertile and well-drained soil, and grows best in slightly acidic soil (PH value 6.2 ~ 6.7). Rotten chicken manure and pond mud can be mixed according to 4 ∶ 6, and pine needles, rotten organic fertilizer and river sand should be mixed at the ratio of 5 ∶ 3 ∶ 2.

Second, lighting

Damulan likes semi-overcast, especially in summer, when the scorching sun shines directly, it is easy to produce "sunburn disease". Therefore, the sun must be shaded in summer, with half-shade and half-sun as well, with thick green leaves; but in winter, there should be sufficient sunshine and good light, which is an important condition for producing large flowers and bright colors.

Third, humidity

Damulan likes to grow in a humid environment, the air relative humidity should not be less than 60%, the leaf color is shiny; the environment is dry, the leaves are dull, even wilting, the leaves are yellowing, and the growth is not good. Therefore, in the summer with high temperature and fast evaporation, sprinkle water on the ground around the basin and spray water on the leaf surface 3 times a day to humidify, cool down and keep the leaf surface clean. But be careful not to make the water flow to the rhizome to prevent waterlogging of the basin soil.

Fourth, watering

To accurately grasp the dry and wet condition of Damu orchid basin soil is the key to watering, the method is not dry, no watering, watering thoroughly. Spring and autumn two seasons exuberant growth, the amount of water can be larger, keep the basin soil moist; "dog days" evaporation is large, such as good ventilation can be more watering, such as muggy weather, poor ventilation, less watering; "three or nine days" basically stop growing, should not be watered, in order to keep the basin soil wet, you can put a layer of moss on the basin surface.

5. Fertilization

Take "thin fertilizer diligently" as the principle, do not apply thick fertilizer or raw fertilizer, avoid leaf scorch and rotting roots. Organic manure should be fully mature. The suitable growth temperature of Damu orchid is 15ml 25 ℃. If it can be controlled within this range, sustainable fertilization can be applied all the year round. If the natural temperature, more should be applied in spring and autumn, less or no in summer and winter. The unflowering plants are often fertilized with nitrogen-rich fertilizers such as rotten cooked cake fertilizer (annual seedlings are not fertilized), and potassium-rich fertilizers can be applied at the end of autumn, which can not only promote the robust growth of leaves, stems and roots, but also improve the ability of cold resistance and disease resistance. For flowering plants, more rotten cake fertilizer is applied in spring, especially in autumn, more phosphorus and potassium fertilizer should be applied, and 0.2% potassium dihydrogen phosphate solution can be used for extra-root topdressing in the morning or evening.

VI. Change the basin soil

Change the basin soil once a year, do not plant too deep, bury the soil to the fleshy root neck, the surface can be covered with a layer of moss.

In the maintenance process of Damulan throughout the year, the pot plants should be often sprayed with clean water, and it is best to dry them with fine cloth after spraying, which can not only increase the smoothness of the leaves, but also improve the ornamental value.
