3The main points of orchid cultivation.

3.1 during cultivation, it is necessary to consider that the root system of orchid is relatively well developed. according to the requirement of hydrophobic ventilation habit of orchid, the flowerpot selected by orchid is more special than the general flowerpot. Orchid pots with coarse texture, beautiful glaze, empty bottom and basin feet should be chosen to raise orchids. Orchid pots are generally large and small, with a deep bottom, like a mouth-up trumpet. There are water holes at the bottom, and there are many small water holes in the lower part of the basin for the purpose of making the roots of orchids more breathable. Newly planted orchids are best planted in tile orchid pots. After being cultivated for more than 1 year, the new root can not be moved to the beautiful purple sand orchid pot until the new root develops normally.

3.2 the key to growing orchids with sandy soil and humus soil lies in the use of soil. Orchids are semi-airroot flowers, which must use acidic soil containing humus and good air permeability. The mountain mud in which orchids grow in mountain areas has a better cultivation effect. Orchid soil can also be prepared by using 70% sandy loam and 30% coarse-grained humus. After blending, it can only be used after stacking for more than 3 years.

3.3 pay attention to the maintenance of wild orchid roots newly dug from the mountain, the new roots of wild orchids have not been sent, and there are more roots broken, first clear the soil from the roots, wash them with clean water, and cut off the withered and scorched leaves. For leaves infected with disease and insect spots, the disease spots should be cut off mercilessly. In addition, the rotten and yellow old roots should be cut off. If the orchid is not fully rooted, the old root and root core without root tip should be retained. It is best to mix the orchid plant with 600x solution of killing alum or medical penicillin streptomycin, each bottle of injection powder is dissolved in 2.5kg water, soak in the solution for 2 hours, and then remove and wash. Drying the orchid root in the sun can activate the vitality of the orchid plant, make the orchid root soft, easy to straighten out, not easy to break, and easy to put on the basin. In order to prevent the orchid leaves from drying, the orchid leaves can be shaded by the sun, usually with about 2 hours of light.

3.4 it is not advisable to water too much water orchids are terrestrial plants that like moisturizing and waterlogging. Many beginners, for fear of lack of water, ended up watering too much water and rotting away the fleshy roots of orchids. The watering principle of the local orchid is that it would rather be dry than wet, as long as the orchid soil is kept moist. On the contrary, orchids cultivated in soilless culture would rather be wet than dry.

Orchids do not have high requirements for moisture, and should be dry rather than wet. In January and February, once every 7 days; in March and April, once every 3 to 4 days; in May, once every 2 days; in June, once a day; in July and August, once every 3 days; from September to December, from twice a day to once a week, and be careful not to get caught in the rain.

Acid-base test paper can be bought at the pharmacy to test the water quality. For those with insufficient acidity, you can add some salt and rice vinegar to the water to adjust it. Orchid watering is very knowledgeable, who should be watered at the edge of the basin. Summer season should be watered in the early morning or evening, avoid watering at noon, the amount of water should not be too large. Generally watering once a week, watering twice a week in summer, watering will lead to orchid root diseases and insect pests. Especially in the continuous rainy weather, the potted soil should be dry rather than wet, and the dry pot is beneficial to the orchid to produce new leaves.

Orchids should be exposed to sunlight from the first half of March to the middle of April. From late April, after 09:00, orchids should not be exposed to the sun. Spring orchids should be exposed to 2 hours a day and shade early every day from June to September. Shading can be postponed after October.

3.6.The newly planted orchids should not be fertilized until the new roots of 2cm grow. Generally, the new roots grow for about 2 months, and some people advocate that they should be cultivated for 1 year or 2 years before fertilization. The fertilizer of orchid can be prepared by ourselves. the method is to use 4 parts of plant ash, 10 parts of bean cake and 6 parts of bone meal, mix them well, store them in a container and add water step by step, and dilute them after fermentation for one year.
