The latest culture methods and matters needing attention of hydroponic orchids

Cymbidium, also known as hanging orchid, fishing orchid, orchid, etc., is a perennial evergreen herb of Liliaceae, with slender and drooping branches, small white flowers when the temperature is high in summer or other seasons, flowers concentrated at the end of the hanging branches, the stamens are yellow, and the inner tender leaves are sometimes purple, which can be watched by potted plants. let's take a look at the breeding methods and matters needing attention of hydroponic orchids.

Planting method of hydroponic Magnolia

1. Container selection: there are many kinds of hydroponic plant containers, which are divided into peat, porcelain, glass, plastic and so on according to the material, and can be divided into transparent, opaque and semi-transparent according to the light transmittance. The root system of the orchid can be watched, so choose a transparent glass container.

2. Nutrient solution: add 1.8g of calcium nitrate, 0.187 g of ammonium sulfate, 0.62g of potassium dihydrogen phosphate, 0.54g of magnesium sulfate, 0.62g of potassium chloride and 0.0278 g of ferrous phosphate per liter. After dissolving, dilute it to 1 liter and mix evenly.

3. Hanging orchid treatment: hydroponic hanging orchids need to deal with the plants dug out from the soil, wash the soil on the roots with water, then cut off the old and rotten roots, leave the whisker roots, and clean up the diseased leaves. It is best to wash the dust and soil on the leaves with clean water to keep the leaves intact.

4. Fixed placement: insert the treated orchid into the bottle and fix it with materials such as glass balls or stones, ensure that the plant can stand upright in the glass container, keep it upright when moving and blown by the wind, and pay attention to maintaining the integrity of the root system. Don't hurt the root system.

Culture method of hydroponic Cymbidium

1. Sufficient water: hydroponic orchids do not need to be watered, but water must be changed frequently. Especially in summer, the plant needs to be cooled by changing water. Usually change every 3-4 days, and sprinkle more water around the plant at noon to keep the air moist.

2. Moderate light: Cymbidium is a shade-loving plant, but it also needs light. Do not put the orchid directly in the sun in summer, you can put it on the windowsill and shade it properly. If the orchid is exposed to the sun, the leaves will turn yellow and lose their luster.

3. Proper fertilization: hydroponic Magnolia is mostly soaked in nutrient solution, which needs less fertilizer, but still needs it. With each change of water, you can sprinkle a few grains of nitrogen fertilizer into the water, preferably in a granular form.

4. change the culture medium: add water and change the nutrient solution every 7 days or so, which can be a common hydroponic nutrient solution on the market or a special nutrient solution, pay attention to timely replacement, keep the water body clean, and clean the roots of the orchid when necessary.

Matters needing attention of hydroponic Cymbidium

1. Cymbidium prefers warm, humid and semi-overcast environment, the optimum temperature for growth is 15-25 degrees, and the overwintering temperature is 5 degrees. The air is too dry, poor ventilation is prone to dry tip phenomenon, too strong sunlight is easy to burn leaves.

2. Add water and flower nutrient solution to the single-layer bottle every 4 days, and the water is input from the straw until the water is full. Change the water of the double-layer bottle once a week, pour out the water when changing the water, wash the bottle clean, fill it with water and flower nutrient solution, and then put the plastic sieve on the bottle.

3. It is advisable to immerse the roots with 1 stroke in water, change every 5-7 days in summer, 7-10 days in spring and autumn, and 10-15 days in winter. It is best to choose tap water standing for 2-3 days, and the difference of water temperature should not be more than 2 degrees.

4. The original strong fleshy roots of Cymbidium hydroponics will rot by root washing method or split method. The water must be changed every day, the roots must be cleaned and the rotten roots can be removed. The new roots can grow in about 25-30 days, and the old roots can gradually adapt to the hydroponic environment before they can be cultivated in nutrient solution.

5. the nutrient solution should be added in the process of changing water. the nutrient solution should be kept in a dry and light-free environment, where it is not easy for children to reach, the temperature should not exceed 35 degrees.
