Cultivation and Management of Orchid

1. Orchid breeding place: Orchid can be cultivated indoors, on balcony, in courtyard, greenhouse or in large-scale orchid farm.

2. Choose orchid basin: clay pot is the first choice for orchids, permeable, breathable, not easy to waterlogging, convenient management, not easy to rot roots.

3. Soil selection: orchids like loose humus soil, mountain forest soil, pond soil or peat soil is the best. Also available broken bricks, weathered aggregates and special granular soil, etc.

4. Orchids for pots and sub-pots: Under normal circumstances in spring and autumn for two seasons, sub-pots most appropriate. If in the summer high temperature for pots, sub-pots, it is easy to make orchid roots infected, orchid leaves yellow and lost seedlings. Winter orchid dormant, the temperature is too low to change, sub-pot, orchid not easy to grow new roots, but also the next year to send the bud infected. Before the pot should check whether there are rotten roots, rotten leaves, if there is pruning off. Before pruning, disinfect the scissors with alcohol, prune and disinfect, mix the pesticide with a basin bucket, soak the roots of bluegrass for about 10 minutes, take them out and dry them, and then put them into the basin.

5. Light and ventilation: orchid growth and other plants can not be separated from light, but not strong light, summer and autumn strong light can be used to cover the sun, such as the temperature is too high available two layers of shade net. Ventilation is the key to the success or failure of orchid cultivation, which requires the upper and lower parts of the orchid cage to be in the air. In the indoor orchid without wind should be given the conditions of air convection, summer fan exhaust available, winter should regularly open doors and windows ventilation, but the temperature should not be lower than 0℃, so as not to frostbite buds and buds.

6. Watering management: the ancients cloud "dry orchid wet chrysanthemum" is to emphasize that orchid grass should be dry, orchid grass can not specify the time to water, but when dry when watering, orchid grass is fleshy root, water is big very easy to rot roots, too dry will make orchid root wrinkle dehydration and die. The supply of water required by orchid grass depends on the absorption of roots and transportation to the whole grass through vascular vessels; the other is that moisture in the air is sucked into the body from the stomata of leaves, so that the water required for metabolism can be supplied. Summer and autumn high temperature dry, especially balcony orchid, should spray some water on the ground to volatilize, artificial space humidity, but also need to spray leaves often.

7. Pest control: Orchid pests and diseases are mainly based on prevention.

(1)Orchid pests are mainly scale insects, red spiders and mites, etc. These pests mainly occur in high temperature and humidity, without ventilation. Control of scale insects can be trichlorfon, etc., according to 1% dilution spraying, pest occurrence period once every 5 days, continuous spraying three times, prevention once a month. Dicofol, acaricide and enemy kill are mainly used for controlling red spiders and mites, and the dilution ratio is according to the instructions of the pesticide.

(2)Orchid fungus disease mainly black spot disease, brown spot disease, anthracnose, leaf yellow disease and so on. Mainly use carbendazim, thiophanate methyl, chlorothalonil, anthrax and other bactericidal drugs, dilution ratio according to the instructions.

(3)Virus diseases include stem rot, root rot, etc. The main control drugs are potassium permanganate, copper sulfate, antivirus alum, etc. There is also an extinct virus called Belas disease, the symptoms of which are irregular yellow-white stains on the surface of the leaves, translucent. The main drugs to prevent and treat this disease are penicillin, isatis root, etc. If the plant is found infected with this disease, it should be isolated or burned as soon as possible.

8. Fertilization management: the root of bluegrass fertilization under normal circumstances as little as possible, organic fertilizer can be used a small amount of bean cake, fishy water, yogurt, etc., inorganic fertilizer can be used a small amount of compound fertilizer, potassium dihydrogen phosphate, etc., generally 3 to 4 times a month. Orchid foliar fertilization, mainly Gaole (high potassium type), high yield Ling, foliar treasure, Aiduo harvest, potassium dihydrogen phosphate, etc., generally twice a month, dilution ratio according to the product instructions

9. Orchid flower proliferation technology: orchid raise good standards, one is blue leaves grow black, strong, green, bright; second, increase the number of seedlings; third, can bloom, bloom well.

(1)To make orchid leaves grow black, strong, green and bright, the key lies in proper moisture, regular foliar fertilizer spraying and pest control.

(2)To make orchids more new seedlings, the key lies in often changing pots, sub-pots. For example, a pot of 5 to 6 seedlings of orchid grass normally sends out 2 to 3 new seedlings every year. If it is divided into three pots, and the orchid bulbs in the three pots are twisted to 180 degrees, so that their lotus roots are broken and connected, 6 to 9 new seedlings can be sent. The germination rate will also increase if each ball of the whole pot is evenly twisted to about 180 degrees without dividing the pot.

(3)Flower appreciation is the greatest spiritual enjoyment of orchid growers. Let orchids bloom in time and on time, giving sufficient sunlight, appropriate temperature and humidity during their growth. Water should be acidic, especially in the case of neutral alkaline water in Shandong area, ferrous sulfate, oxalic acid and other improvements can be used. Fertilizer to use partial potassium, more plant regulators, on the pot as far as possible when the bulb exposed to the soil surface, control moisture to dry mainly.
