How to cultivate a leaf orchid in hydroponics?

One leaf orchid is not called spider holding egg, big leaf evergreen, bamboo tendon and so on. It is a perennial evergreen persistent herb of Liliaceae, which can absorb formaldehyde, carbon dioxide and hydrogen fluoride. It can also absorb a certain amount of dust. Let's take a look at how to cultivate a hydroponic orchid.

Growth habits of Cymbidium mongolica

One-leaf orchid is native to the provinces and regions of southern China, and is now cultivated all over China. It is widely used, evergreen all the year round, elegant plant type, small and lovely flowers, and is loved by people. Sex like warm and humid, semi-overcast environment, more cold-resistant, extremely shade-resistant. The suitable temperature for growth is 10: 25 ℃, while the range of growth temperature is 7: 30 ℃, and the overwintering temperature is 0: 3 ℃.

Ramet Propagation of Cymbidium chinense

The main results are as follows: 1. Ramet time: Cymbidium is very suitable for family breeding, and the method of ramet can be used to propagate when raising Cymbidium. The ramet propagation of Cymbidium can be divided in combination with changing pots before the new buds sprout before the temperature rises in spring. It is usually carried out after the soil is thawed in early spring (February and March).

2. Split method: take the mother plant out of the flowerpot, shake off the excess potted soil, separate the root system as much as possible, and cut it into two or more plants with a sharp knife. Each plant should have a considerable root system, and its leaves should be pruned properly, so that each clump has 5 leaves in order to survive.

How to cultivate a leaf orchid by hydroponics?

1. Selection of utensils: according to the specific conditions of the varieties, forms, specifications and colors of one-leaf orchids, select substitute bottles, pots, vats and other instruments that can complement and complement each other with the varieties of one-leaf orchids, and purchase or process and make themselves in accordance with the principles of the selection of hydroponic instruments, so that they can be used appropriately and elegantly, and the instruments used must not be taken or misused at will. So as not to affect the image of hydroponic orchids and the beauty of interior decoration, so as to achieve unity and harmony between utensils and flowers and the living environment, so as to achieve a more ideal ornamental effect.

2. Removing soil and washing roots: soil cultivation is organic nutrition, but after changing to water culture, it is completely changed to inorganic nutrition cultivation, and the organic matter in the soil and attached to the root system should be strictly cleaned so as not to affect the normal growth of hydroponic Cymbidium and the infection of diseases and insect pests. The method of root washing is to dig out the selected flower plants from the soil or gently pour them out from the flowerpot, first gently lift the branches with the right hand, gently support the root system with the left hand, change the right hand to gently shake, and slowly pat, so that the root soil falls off and reveals all the roots. Then soak in clean water for 15 to 20 minutes, gently wash the roots with hands, change water for 2 or 3 times, until the roots are completely soil-free, and wash the roots when the water is clear and transparent without sediment. There must be no soil left, which is one of the important links in the success of hydroponics, and we must not be negligent.

3. Cut off the old root: after washing the soil, the old root, diseased root and old leaf yellow leaf can be properly cut off according to the growth of the flower root system, because the hydroponic one-leaf orchid root is also an important part of ornamental. Therefore, when finishing the root system, we should also consider the beauty of its shape. After pruning its roots and leaves, wash them again in clean water to wash away the residue of root hair left when cutting, so as to avoid pollution caused by hydroponics.

4. Root disinfection: after cleaning the root system of a leaf orchid, prepare 0.1% potassium permanganate aqueous solution and place it in a plastic or enamel basin. The amount of solution can be determined according to the number of one leaf orchid soaked, and several or more one-leaf orchid can be soaked at a time. The standard is to submerge all the roots. After soaking for 10 or 15 minutes, take out the solution, then wash it in clean water and plant it. Note that the root disinfection time should not be too long or too short, and the degree of potassium permanganate solution should not be too thick or too thin. In addition to using the balance scale, the appropriate ratio mainly depends on the empirical preparation and seeing the color of the solution (light fuchsia).

5, scientific planting: if it is a glass vase, because the glass is thicker and has a certain weight, you can carefully put a leaf orchid root system into the vase. In order to make a leaf orchid stand upright, you can fix it with stones or pebbles around the mouth of the bottle, and then pour it into the bottle body 2pm 3 moisture can be, pay attention to stretch the root system. If you use a plastic vase, because the texture is very light, it is difficult to support the one-leaf orchid plant even if there is water, resulting in top-heavy and lodging, so you can put a certain number of stone particles in the bottle before planting to increase the weight of the vase, and then insert the leaf orchid into the vase as before. If you use other flowerpots without bottom holes or use round and oblong fish tanks to grow hydroponic flowers, the problem of root fixation in water must be considered.
