Cultivation of Cymbidium: the method of Managing Cymbidium in Autumn and Winter

The varieties with early flowering in Siji orchid generally finished flowering before the Mid-Autumn Festival and entered the stage of new seedling maturity and autumn bud growth. The growth of the seedlings will continue to be completed in the southern 11th century. At this time, as the flowering period has passed and the weather is cooler, fertilization can be thicker. With phosphorus, potassium, nitrogen and 2:3:5, some solid slow-acting fertilizers can also be applied appropriately, so that they can get a more comprehensive supply of nutrients in the next few months. At this time, you can also change the basin and split plants. It can also be loosened between the heads of mature Reed in the original basin to sprout new buds, so that the basin soil can be naturally dried within three days after changing the basin, so that the wound will not be infected and then drenched with water later. Although the heat wave decreases slightly in autumn in the south, the wind is especially dry. It is called the autumn tiger. If you are not careful, it will easily cause black spots or anthrax in the new seedlings of that year, so it is more important to maintain ventilation and a milder culture environment. In winter in the south, except for some snowy and frosty places in northern Guangdong, most of them can spend the winter in the open air, and the ones that really reach below 10 degrees are only a few days a week after the cold spell, so it does not affect the growth of orchids. On the contrary, it has a relatively low temperature period to make its new buds differentiate below the basin surface, which can break out earlier in the early spring, so the southern four seasons can maintain a certain humidity during the winter. So that the growth of buds will not come to a standstill, so many southern orchids have found that some of the strong buds will grow after the cold spell. In the north, it is more clear when it is cooler in autumn. Because the new seedlings germinate more slowly in early spring than in the south, most of the seedlings have not yet grown well at this time. At this time, the proportion of fertilizer can be 2:4:4. And in a ventilated environment to keep the plant moist but not wet, the growth of seedlings will be significantly accelerated. There are dry and cold and wet cold in winter in the north, it is better for orchids to spend the winter indoors, placed near the window sill and placed near the light level of the windowsill, the basin surface can be added with black nutritious soil pavement, on the one hand, it can be moisturized and the other is easy to absorb heat, and several holes can be used in transparent plastic bags to cover the orchid plant and basin noodles, leaving the basin bottom breathable, and strive for full sunshine as far as possible when there is sunshine in the morning, but it should also be shaded properly when the ultraviolet is too strong. Watering depends on the local environment. If the air humidity is less than 60% and the basin temperature is about 10 degrees, it can be watered every two days, and each place can be watered according to the actual situation. Cold weather in winter, generally do not carry out foliar spray to prevent frostbite (there is a greenhouse or greenhouse can), especially in cold and wet cases, often found in the warm spring days after the frostbite scorched orchid leaves. In the cold winter of December, the four seasons are in a dormant state, the growth of buds is extremely slow is a normal phenomenon, there is no need to add fertilizer indoor heating to achieve the effect of winter buds, in fact, it is not true, on the one hand, it is against its natural growth law. second, the fertilizer could not be attracted in the basin and stored in the plant material and orchid basin after dissolving the water body, so that the growth of orchid plants was seriously damaged. The three indoor heating, such as humidity and light can not be matched accordingly will only cause scorched leaves, no gloss and other problems, (such as the greenhouse is equipped with various factors).

The varieties that bloom late in the four seasons orchid generally blossom around the Mid-Autumn Festival, and their flowers are glutinous and thick, and their fragrance is far away, so the flowers that bloom near the Mid-Autumn Festival are called Qiujian, which is the top grade of the four seasons flowers. Pots can be divided within a week or two after flowering. Since the growth point of pseudobulbs after anthesis is easily affected by natural humidity and temperature, high humidity can be maintained after flower cutting and potting. Under the action of convective wind, new buds generally grow within two weeks, and water moss is mostly covered by moisturizing method, but water moss can be removed after new buds grow, as long as the basic fertilizer is guaranteed in the remaining two months. Before the cold spell, it will grow into sprouts around 10CM, and after the age of Fang, it can continue to grow and renew again and again.
