Maintenance methods of bonsai of Cymbidium

Use soil: loose and fertile neutral or weakly acidic humus soil should be used. Fertilization: apply appropriate amount of fertilizer, do not apply thick fertilizer and raw fertilizer that has not been fermented. Watering: watering must be thoroughly watered, more watering should be done after budding, and watering should be controlled when room temperature is low to prevent the basin soil from getting too wet. Temperature: give it a growth environment of 15 ℃ and 20 ℃, not less than 10 ℃.

1. Use soil

The original place of the orchid is under the trees of the high-altitude forests of southern Africa, and its roots are rooted in the decaying leaves accumulated over the years. The bonsai of Magnolia should be made of loose and fertile neutral or weakly acidic humus soil, which can be mixed with 65% humus soil, 20% net sand and 15% fine furnace ash. The relative humidity of the soil should be about 40%. If the soil is hardened and the drainage is not smooth, it will lead to rotting roots. When changing soil in spring, it is best to buy special soil for planting. The special soil is rotten leaf soil, which is very suitable for the growth of Cymbidium.

2. Fertilization

The magnolia should be applied once in winter with solid fertilizer, less nitrogen fertilizer, more phosphate fertilizer and potash fertilizer. Eggshell powder and retting fish water is a good phosphate fertilizer, bran ash and soot are easily available potash. Nitrogen, phosphorus and potassium compound fertilizer can also be applied to promote the germination of more new plants and leaves. Fertilization must be appropriate, do not apply thick fertilizer and unfermented raw fertilizer, otherwise, it is easy to cause leaf tip scorch or rot. In winter, if the new leaves are spotted and the roots are yellow, it means that there is too much fertilization, while the narrow, thin and light color of the new leaves is a sign of lack of fertilizer.

3. Watering

The soil should not be too dry or too wet. Every time it is watered, it must be thoroughly watered, and some more should be watered after budding. Every 20 days or so, combine watering with fermented bean cake water, fresh fish water and horseshoe water to combine watering and fertilization. Watering should be controlled when the room temperature is low to prevent the basin soil from being too wet, which will cause the rotten roots of the plant to die, but it can not make the basin soil too dry.

4. Temperature

The suitable temperature for the growth of Cymbidium in winter is 15 ℃ 20 ℃, and it is better not lower than 10 mol. The temperature should be kept at about 18 ℃ after scurrying, and the temperature difference between day and night should be about 10 ℃, otherwise the flower arrow will blossom if it does not reach a proper height, and it is easy to form a "sandwiched arrow". The magnolia should be moved indoors when the outdoor temperature is lower than 10 ℃ at night. When the indoor temperature is lower than 10 ℃, in addition to covering the surface of the basin soil with a layer of 1 cm thick charcoal powder, the flowerpot should also be placed in the indoor sunny warm place. When the indoor temperature is very low, cover the film on the flowerpot to raise temperature, but the temperature in the cover should not exceed 25 ℃, if it exceeds, it should be ventilated and cooled in time.

5. Lighting

The magnolia is easy to blossom in short days. Hot sun exposure, summer direct sunlight will get sunburn, inhibit growth. It should be cultivated in a shady shed or in a semi-shady environment without direct sunlight from May to September every year. But the longer the sun shines in winter, the better. Low light can prolong the flowering period during flowering. It likes to be warm and cool, and avoids severe cold and heat. It generally grows well at a temperature of 18 ℃ and 20 ℃, and stops growing below 5 Mel. After the orchid enters the room, the light is limited and needs to be adjusted by manually moving the flowerpot. Under normal circumstances, the flowerpot should be placed indoors in the sunny place during the day so that the sun can shine on the plant. Before flowering, flowerpots should also be placed under fluorescent lamps to replenish light at night. Because the two rows of leaves of Cymbidium are opposite, if the light is in one position for a long time, it will make the leaves grow unevenly and affect the ornamental effect. Therefore, when adjusting the light, we should pay attention to the direction of the leaves and change to the sunny side every 10 days or so. There are two ways to arrange the flowerpot indoors: one is to make the leaf parallel to the sunny window, and the other is to make the leaf perpendicular to the sunny window, and the effect of the latter is better than the former.

6. Florescence control

The florescence of Magnolia is mostly from December to March of the following year. The way to prolong the flowering period is to place the flower in a dark place when it is about to bloom, properly control the watering, and keep the temperature at 8 ℃ 12 min. In this way, the florescence can be prolonged by 10 mi for 20 days.
