Sex likes yin and avoids direct sunlight. Therefore, it should be properly shaded and placed in a place that can absorb scattered light but avoid direct sunlight.

2. Temperature. Cymbidium grows best in the environment of 15 ℃-30 ℃, and grows poorly above 35 ℃. The severe cold below 5 ℃ will affect its growth, and the orchid will enter the dormancy period.

3. Soil. Bract glossy orchid is a fleshy root, which is suitable to use sandy loam rich in humus with good drainage. Generally, rotten leaf soil or mountain soil, slightly acidic loose soil or iron-containing soil are selected, and the pH value is 5.5 ~ 6.5.

1. Watering. Glossy orchid in summer is a period of vigorous growth, and if it is short of water, it will grow badly. The growth of glossy orchid should follow the principle of "dry is watered, wet is stopped, and properly dry", and watering should be thoroughly watered.

2. Fertilization. Cymbidium likes fertile land, and farm manure needs to be compost and mature for more than a year before it can be applied. There is not much fertilizer needed in the growing period, and dilute liquid fertilizer can be applied every 10 minutes and 15 days.

2. points for attention:

1. Control the temperature reasonably. If the temperature is too high, the leaves will burn or scorch. At this time, you should spray around, lower the ambient temperature and shade properly. If the temperature is too low, there will be frostbite, so the orchid should be transferred indoors in time.

2. Maintain good ventilation. Glossy orchid is suitable for planting in a well-ventilated environment, so it is often ventilated to maintain humidity and fluidity in the air.

3. Apply fertilizer to avoid touching the leaves. When fertilizing, be careful not to stain the fertilizer liquid on the leaves, nor on the roots of the orchid, so as not to cause the decay of the leaves and roots.

How to install the pot of glossy orchid

2. Pour the mixed gravel into about 1/3 places at the bottom of the basin, then pour the medium-grained mixed soil into four-fifths of the flowerpot, then take out the branches, compact the soil, and do not reserve space.

3. After that, pour large grains of gravel into the flowerpot, keep the 1.5 cm gap along the pot, finally pour into the bean seed, bury all the false bulbs in the soil, gently press the plant material with earth pressing tools, and flatten the surface. After planting, it is best that the plant material is slightly higher in the middle of the basin.

Diseases and insect pests of Cymbidium bracteatum and its control

1. Anthrax. It can happen all the year round, and the high temperature and rainy season is more common. The disease spot spreads from the leaf tip to the rhizome, at first it is brown, then gradually expands and increases, there are many dry black spots, and in severe cases the plant dies.

Prevention and treatment: during the onset period, 50% methyl topiramate wettable powder can be sprayed with 1500-fold solution, once every 10 days, and then supplemented with 1% equal Bordeaux solution, once every semimonthly, for 3 consecutive times.

2. Scale insects. Commonly known as "blue lice", it multiplies fastest under the condition of high temperature, high humidity and poor air circulation. It will suck the sap from the leaves of the orchid, causing the leaves to fall off, slow plant growth and serious plant death.

Control method: 1% omethoate or 1500 times 50% Mala sulfur was sprayed during the incubation period. If the number of domesticated magnolia is small, it can be brushed off manually.

In fact, the cultivation of Magnolia is not difficult, in breeding, we must pay attention to temperature control, summer to do a good shade treatment. In the process of breeding, timely watering, plant diseases and insect pests and fertilization are all very important. Only by doing these work well can we ensure the good growth of Magnolia.
