The potted soil should have good drainage ability and be suitable for growing in sandy loam rich in humus. The soil can be mixed with fertile garden soil, rotten leaf soil and river sand.
The growth environment of wine bottle is 20-28 ℃. It can survive in 33 ℃ high temperature environment, but it is not cold resistant. Generally, it will stop growing at about - 13 ℃ in winter, and keep the temperature above 10 ℃ in winter, otherwise it will lead to the decay of the base, which will make the plant wither.
Magnolia is suitable for growing in the environment with sufficient light. Because of its strong growth ability, it is also resistant to certain shade. Lack of light will cause the leaves to become thin and weak, which is not conducive to the survival and development of plants.
In addition to summer, the Magnolia needs to receive sufficient sunlight to ensure its growth. During the growing summer, it needs to be shaded. The shaded area is more than half of its own area, and one side of the leaves is yellow and withered.
When receiving the light, it is necessary to move regularly to facilitate uniform light, so as to make the plant have a beautiful shape. It is better to turn the flowerpot once a month and a half.
The bottle is wet. Therefore, the relative humidity of the air should be kept at 70% - 80%. If it is too low, the leaves will turn yellow, wither, or fall off, dim, affecting the overall ornamental value.
Because of its thick rhizome, it has good drought resistance. It can grow and develop without watering for half a year or so. As long as the humidity of the wine bottle orchid is well controlled, it can ensure that the basin soil is slightly dry, reduce watering in autumn and winter, and no water can accumulate in the basin.
In general, the compound fertilizer or liquid fertilizer containing nitrogen, phosphorus and potassium should be applied to the wine bottle orchid, and the fertilization should be stopped in winter.
As long as it is well maintained, the wine bottle orchid will grow very fast. When it grows to a certain size, it should be considered to change a larger basin for it to continue to grow vigorously. One of the following can be selected as the culture soil and component proportion for basin changing: vegetable garden soil: slag = 3:1; garden soil: medium coarse river sand: sawdust (dregs) = 4:1:2; or paddy soil, pond mud, rotten leaf soil.
Move to a bright place for maintenance.
In the outdoor, it can be wrapped with film to survive the winter, but every two days, it is necessary to uncover the film at noon when the temperature is high to let it breathe.
Light: sufficient sunshine can be given in autumn, winter and spring, but shade more than 50% in summer. When it is placed in the room for maintenance, it shall be placed in the place with bright light as far as possible, such as the living room, bedroom, study and other places with good lighting. After indoor maintenance for a period of time (about a month), it is necessary to move it to a place with shade (with insulation conditions in winter) for maintenance for a period of time (about a month), so it can be exchanged alternately.
Fertilizer and water: for potted plants, in addition to adding organic fertilizer when potting, proper fertilizer and water management should be carried out in the ordinary maintenance process. Spring, summer and autumn are the growth peak seasons of Magnolia. The fertilizer water management follows the following sequence: fertilizer water fertilizer water water water. The interval period is about 1-4 days. The interval period is shorter in sunny or high-temperature days, longer or no watering in rainy or low-temperature days.
In the winter dormancy period, the main task is to control fertilizer and water. The fertilizer and water management should be carried out in the following order: Fertilizer - clear water - clear water - fertilizer - clear water - clear water, with an interval of about 3-7 days. For the plants planted in the field, according to the drought situation in spring and summer, apply 2-4 times of fertilizer and water: first, separate a circle of small ditch 30-100 meters away from the root neck (the larger the plant is, the farther away from the root neck), and the width and depth of the ditch are 20 cm. 25-50 Jin organic fertilizer, or 1-5 two particles of compound fertilizer (chemical fertilizer) are sprinkled into the ditch, and then water permeable is poured. After winter and before spring, fertilize again according to the above method, but do not need to water.
Pruning: in winter, when the plant enters into dormancy or semi dormancy period, it is necessary to cut off the branches such as thin, weak, disease and insect, dead and too dense. It can also be combined with cuttage to arrange the branches.
Diseases and insect pests will also affect the growth and development of Magnolia, especially leaf spot. Bordeaux solution of 1:1:100 can be sprayed once every 15 days for control. The main pests are whitefly and scale insect, which can be controlled by spraying 40% of the nourishing dimethoate emulsion.
