Such as the great victory, dyeing factory, oil craftsman Lao Chen, and victory, Huang technician short leaf monk, round head, holding head monk, spring city short leaf and so on.

Native to southern Africa. I like half yin. I'm afraid of bright light. Like warm and cool climate. A slightly acidic soil with fertile, loose and good permeability is required.

3. Main points of cultivation.

(1) Basin soil

When potted, choose sand and peat or sand and rotten leaf soil. The basin of the adult seedling should be changed every 2 ~ 3 years, and the size of the basin is determined according to the seedling. Change the soil when changing the basin, and retting at the same time with cake fertilizer, barnyard manure, etc., in order to promote the rapid growth of Magnolia.

(2) watering

The gentleman orchid likes the warm and humid environment, its fleshy roots are well developed, and it has a certain ability to withstand drought, but it is afraid of waterlogging, and it is necessary to master the principle of humidity between dryness and wetness when watering. It is best to keep the relative humidity of the soil at 80%-90%, not less than 60%. Wash the leaf surface with tea water every week to make the leaf surface fresh and bright. In short, the four seasons as long as the spring bogey wind, summer sunscreen, autumn rain, winter is not dry to maintain exuberant plant growth, luxuriant flowers and leaves.

(3) fertilization

Magnolia can be fertilized after 1 month of slow seedling, fertilize and water once in 10-15 days, and stop application in summer. Half a month before the arrival of the two growth peaks in spring, it is appropriate to apply dried bean cakes or chicken dung in the basin, but not too close to the root, so as not to hurt the root. After autumn begins to conceive buds and blossom, it is necessary to increase the application of phosphate fertilizer to make the flowers big and colorful, and can prevent the occurrence of arrows. When applying fertilizer, do not pour it on the leaves or in the leaf sheath. If the fertilizer is not enough, the leaves are not glossy, the flowers are few and small, and there will be the phenomenon of blooming every other year. Regular topdressing is generally carried out in spring and autumn, but less in summer and winter.

(4) Lighting

The leaves of Magnolia are broad, according to a certain shade-tolerant, like semi-shade environment, the leaves of plants growing in 50% light transmittance environment are green and green, which can greatly improve the ornamental effect. The light will also affect the arrangement direction of the leaves of Cymbidium. On one side, the leaves that were originally arranged in a shape will be confused, resulting in a decline in ornamental effect, so we should pay attention to let the plants receive light evenly and rotate the direction of the basin regularly.

(5) temperature

The suitable temperature of Cymbidium is 15-20 ℃. When the plant growth is higher than 25 ℃, the plant growth is poor, and the excessive growth of leaves often occurs, which affects the flower bud differentiation. At this time, attention should be paid to ventilation and cooling; when it is lower than 10 ℃, the growth is slow; when it is below 0 ℃, the plant will freeze to death. Attention should be paid to cooling in summer, which can promote flower bud differentiation. The temperature difference between day and night is large, which is beneficial to the growth of Cymbidium, and the suitable temperature is 6-10 ℃.
