The latest Culture method of Cymbidium

Single garlic orchid is orchid single garlic orchid semi-epiphytic herbs, pseudobulb ovate to ovate cone, the upper end has a clear neck, often born in evergreen broad-leaved forest or shrub edge humus-rich soil or moss-covered rocks, this flower has cultivation, with high horticultural value, let's take a look at the cultivation method of single garlic orchid!

Growth Habits of Solanum nigrum

Solarium like cool, ventilated semi-shade environment, cold, winter does not dormancy, winter minimum temperature-10℃ above, suitable for planting in loose, breathable, good drainage fern roots, moss or humus soil. I like the weather with four distinct seasons. Summer temperatures should not be higher than 25 degrees Celsius, occasionally a few days 30 degrees Celsius high temperature can also be tolerated. Winter dormancy period, the temperature requirements close to freezing point, that is, the ideal 1 to 5℃, this temperature and the general refrigerator is basically the same, low temperature dormancy after a period of time will sprout new buds.

A method of propagation of Solanum nigrum

The plant is usually propagated by dividing or aseptic sowing, because its embryo is incomplete and can only be sown in culture medium under aseptic conditions, and the plant is divided after flowering. Like warm and humid and semi-shady environment, with peat, moss or humus shallow pot planting, just transplanted plants should be controlled watering, to prevent pseudobulb rot. During the growing season, thin fertilizer should be applied, and the rhizosphere should be well ventilated and drained. In autumn, it will gradually enter dormancy. After the leaves are dried, the pot soil will remain dry until the next spring before germination.

Culture method of single garlic orchid

1, choose basin: pottery basin and plastic basin can be. Pottery pots need more frequent watering. Evaporation of water from the surface of pottery pots helps keep the root environment cool. The advantage of plastic pots is that they do not need to be watered frequently and are clean and portable. Many people plant them in half-height pots because wild Solanum plants have shallow roots. It has been found that they can develop fairly well developed roots if provided with deep pots. Be sure to clean and disinfect flowerpots before planting.

2, substrate: potted substrate requirements loose, permeable and good ventilation, water retention capacity should also be strong. Therefore, the common garden soil and potting soil are not suitable for planting Solanum uniflorum. The culture medium of epiphytic orchids or semi-epiphytic orchids can be selected as pot culture material, and there are many kinds of proportions. The commonly used ones are 6 parts of bark for planting epiphytic orchids, 1 part of coarse pearlite, 1 part of moss cut into 5~6 mm long and 1 part of peat crushed.

3, on the pot: garlic orchid should be in the dormant period on the pot or change pot, generally at the end of January and early February, pseudo-corms should be exposed to one third of the pot soil, old roots do not need to be trimmed, in order to facilitate stable corms, corm planting spacing about two centimeters, a few varieties of pseudo-corms are required to be completely buried in the matrix. When potted, the lower 2/3 of the pot body is filled with the coarse particles mentioned above, and the finer ones are filled on the top. Fill the circumference of new pseudobulbs with fine bark pieces and shorter mosses.

4. Watering: The key period of watering is the early stage of the growing season, when the root system of Solarium orchids has just begun to grow and the flowering period enters the end. Small amounts of water should be given to keep the substrate moist only, in order to promote rooting. At this time, if you water too much, it is easy to rot roots. After a period of time, when the root system basically grows well, you can start watering a lot.

5, fertilization: garlic orchid like small fertilizer frequently, fertilization can only be carried out in the flood period, the initial application of higher nitrogen fertilizer, and then to phosphorus, potassium higher formula. In Australia, horse dung has been used directly as a substrate, and success has also been achieved.

6, light: garlic orchid can tolerate direct sunlight, but the best summer growth period shade 50%. Outdoor shade is a good place to grow, and like other orchids like air circulation.

Control of diseases and insect pests of Solanum nigrum

1. Leaf spot disease: leaf spot disease mainly harms the leaves and buds of Solanum nigrum, which can be controlled by 1% bordeaux mixture, 50% carbendazim, 50% thiophanate-methyl 1000 times solution or 40% dimethoate emulsion 1500 times solution.

2, sheath rust: usually on the upper and lower surfaces of the leaves, less raised blisters on the stem, containing yellow, orange, rust or even purple-black powdery spores. Rust does not kill, leaves do not die, but it weakens plant growth. In addition to cutting off the diseased leaves, 65% zineb powder 500~600 times solution or copper-containing fungicide can be sprayed.

3, white silk disease: white silk disease occurs mostly in the rainy season. At the beginning of the disease, the leaf base was covered with white threads. Causing the rhizome to rot. The control method is to remove the soil with bacteria and sprinkle pentachloronitrobenzene powder or lime. Radical cure method: pay attention to ventilation and light transmission, basin soil drainage is good. Seriously sick plants burn.

Anthracnose: The disease spots extend from the leaf tip to the rhizome first, initially brown, and then gradually expand and increase, with many dry black spots appearing, which in severe cases lead to the death of the whole plant. In addition to actively improving environmental conditions, 50% thiophanate-methyl WP 800~1500 times solution can be sprayed once every 7~10 days, and then supplemented with 1% equivalent Bordeaux mixture, once every half month, continuously sprayed 3~5 times.

5. Scale insects: scale insects parasitize the edge or back of leaves of plants to absorb juice, causing plants to wither. In severe cases, the whole plant will wither and die, and the secretion of scale insects will also cause black mold. It can be sprayed with 50% omethoate emulsion, 50% malathion, 25% imine emulsion or 80% dichlorvos emulsion 1000 times, generally sprayed once every 5~7 days for more than 3 times.
