Orchids should bloom in four seasons, focusing on winter and summer.

Orchid is a kind of flower plant that can be seen in leaves, flowers and stems. However, the maintenance of orchids, there are too many people are not sure, in addition to daily watering and fertilization and other work, want to see orchids bloom in the four seasons, florists should focus, and this focus should be on "winter and summer."

Point one: winter

The maintenance in winter is related to the growth and flowering of orchids in the coming year. Florists need to do a good job in the following maintenance methods:

1. Enter the room to keep warm

Jianlan, Mulan and Hanlan have poor cold resistance and should enter the house early. Chunlan and Huilan should also enter the room when they are frozen. The room temperature should be kept at 5-15 ℃, and the room temperature should be controlled at 3-8 ℃. Generally, 15 ℃ is suitable, which is higher than 15 ℃, which has adverse effects on the development of flower buds and arrows.

2. Control watering

Summer and autumn can not be dry, winter and spring should not be wet, this is the previous experience of raising orchids. Generally keep the basin soil some wet can safely survive the winter, if the basin soil has been dry, then in the warm weather around noon, with water similar to room temperature spray, basin soil slightly wet. Do not flood water to prevent rotting roots and frostbite. When watering, gradually flow into the flower root from the edge of the pot, until the flower root is wet, do not water the leaf and orchid core.

3. Control fertilizer and increase light

Orchid hibernation generally do not apply fertilizer, orchid root has no whisker root, there is mycorrhizal symbiosis in the root, spring orchid, cold orchid growth, the leaf can be sprayed 0.1% potassium dihydrogen phosphate or orchid general organic liquid fertilizer, diluted 500 times to water the root. Orchids should have sufficient light in winter and should be placed on the sunny side of the closed balcony, so that they can receive light sooner or later, such as insufficient light, there should be lights to supplement.

4. Timely ventilation and ventilation

Orchid spring warm need air circulation, afraid of smoke and dust pollution, away from the stove, sunny day around noon window ventilation, orchid pot end in the outdoor shelter to the sun to see the sun, the temperature dropped immediately back to the room.

Point 2: summer

1. Shading

Orchids like a cool and shady environment and are afraid of direct sunlight. Shading should be given from late April to the end of September every year, with a shading rate of 50% and 70%. Chunlan and Huilan have higher requirements for light, and the shading rate of Jianlan and Mulan is more than 80%. Shade net is used for shading, and the orchid basin is placed near the water surface or in a place with fresh air and good ventilation.

2. Rain protection

The rainy season is the exuberant stage of orchid growth. continuous wet soil will affect the growth of leaf buds, cause black spot, rot and die, so there should be a rain shelter and move it indoors before it rains. Summer temperature is high, the light is strong, to ensure enough moisture, in addition to watering, but also need to spray water upward into the air, can cool and humidify. The heavy rain splashes the basin soil on the orchid heart or orchid leaf, which will cause brown rot.

3. Fertilization

To fertilize orchids in summer, we should abide by the principle of frequent application of thin fertilizer, with organic nutrient solution, diluted 500 times, once a month. Spring orchid, Huilan, summer nitrogen and potassium fertilizer, Jianlan phosphorus and potassium fertilizer, cold orchid do not apply fertilizer. Fertilization can not pollute the leaf surface, before and after flowering, do not apply fertilizer in the summer.
