Culture methods and matters needing attention of Cymbidium

The first thing for many orchid friends to buy ink orchid is to consult an article on "breeding methods and precautions of ink orchid" to be prepared. This paper discusses the breeding methods and matters needing attention with flower friends from many aspects, such as ink orchid habit, environment, watering, fertilization and so on.

1. The habits and conservation environment of Cymbidium.

Ink orchid likes warm, humid and well-ventilated environment, likes water, thin fertilizer and high humidity air, avoids direct light, avoids stagnant water in the basin, is basically similar to asparagus, its growth is slow, the plant is not easy to age, the leaf is thick and green, and the flowering period is from January to March. 10:00 in the morning, 7 o'clock in the evening is more obvious, and related to the environmental temperature.

Family indoor culture of Cymbidium must be ventilated on four sides, and the indoor relative air humidity is not less than 50% and 80%, and the humidity is not enough. The high-foot orchid basin is equipped with a water basin to store water to increase local air humidity, and the water depth of 1.5 cm ~ 2 cm is suitable. In order to prevent the corruption of the growing bacteria in the basin, salt can be added in the basin, and the water can be changed not less than once a semimonthly. Dry weather requires foliar spray 2 or 3 times a day to increase humidity. However, before closing the window, we must ensure that there is no stagnant water on the leaf surface and leaf tip (plant heart), otherwise the perishable leaves and stems.

The air humidity is high in the plum rain season, so the above operation measures are omitted.

During the winter heating in the northern region, special attention should be paid to increasing indoor air humidity to prevent the scorched tip of leaves and buds from withering buds.

Lighting: in addition to winter and spring, should not directly receive direct light, winter and spring can be exposed to the morning sun for about 2-3 hours every day, summer and autumn need shading.

Temperature: no less than 3 ℃ in winter and no more than 30 ℃ in summer. The suitable temperature for growth is 20 ℃ ~ 28 ℃.

2. Watering and fertilizing methods and specific operations:

The watering of the orchid is the same as that of other orchids. It is necessary to keep the basin soil moist and not dry enough to water again. It is watered in the morning in winter and spring, and begins after sunset in summer and autumn. Generally, it is watered every 4-7 days in winter and spring, and every 2-3 days in high temperature and dry season in summer and autumn. According to the dry and wet condition of basin soil, cloudy and sunny weather and air humidity, we can flexibly grasp the watering frequency and can not fix the mode.

Note: generally do not water on cloudy and rainy days (unless the basin is dry), do not spray within three days after spraying. The temperature of watering water should not be too different from the soil temperature, which will cause the plant to catch a cold.

The leaves of Cymbidium are broad, thick and tall, which are different from other orchids and need more nutrients during the growing period. Therefore, it is necessary to adhere to thin fertilizer and diligent application. Solid granule slow-release fertilizer (N/P/K ratio refers to Haokangduo) can be evenly distributed along the edge of the basin (depending on the size of the basin), the particles can not touch the root and pseudo-corm, prevent root burning, and supplement the slow-release fertilizer in time according to the fertilizer effect time. Compound liquid fertilizer is applied every half month from May to October (once a week during the peak growth period). Organic fertilizer is not recommended for family flower cultivation, so as not to produce exhaust gas and insect pests to affect the indoor air and environment.

Note: no fertilization in overcast and rainy days, no fertilization in florescence, less fertilization in summer high temperature season, if the plant growth is very weak, the concentration should be halved according to the instructions. After 24 hours of application of liquid fertilizer, the basin soil was washed with water to reduce the accumulation of harmful inorganic salts. The plants just put on the pot and just changed the soil need to be fertilized after 30 days (foliar spraying of liquid fertilizer). Before and after the flower buds were unearthed, stop using compound liquid fertilizer and spray leaves with potassium dihydrogen phosphate or other phosphorus and potassium fertilizer once a month until winter.

3. Sterilization, anticorrosion and disinfestation

During the growing period, Cymbidium is easy to suffer from bacterial fungal diseases such as bud rot, root rot, charcoal maggot, black spot and so on. From April to winter, you should insist on spraying and root irrigation once or twice a month: the main drugs are potassium permanganate (5000 times aqueous solution), carbendazim, methyl topzine, etc., exchange use, otherwise anti-drug, use in dissolved water according to the instructions, rather thin than thick, do not apply fertilizer, water spray three days later.

There are very few insect pests in the family, so close the screen window and clean the sanitary dead corner can put an end to the occurrence of insect pests.
