Jinzuan green velvet, also known as Jinzuan, is a foliage plant. Its vitality is very strong, with the role of air purification, suitable for home, office buildings and other places. But Jinzuan's leaf juice can be poisoned in the mouth, and its roots, stems and leaves are poisonous. You should pay attention to it when breeding. Today, let's learn the cultivation method of jinzuanman green velvet!
Cultivation method of jinzuanman green velvet: jinzuanman green velvet is native to the tropical rain forest in Brazil, South America. It likes warm, humid and semi overcast environment, and has no strict requirements on light, but it can't tolerate long-term shade environment, otherwise, the leaf color will be lighter, the petiole will be longer, and the leaf will droop and the ornamental value will be reduced. And fear of strong direct light, after strong light, leaves are prone to dry tip, leaf edge scorch edge, leaf color whitening and tarnish, so it is best to half shade or scattered light maintenance. In winter, enough light can be used for nursing, so that it can live through the winter safely.
Jinzuanman lvrong is a tropical plant, which is not resistant to severe cold and low temperature. It is better to keep the temperature above 10 ℃ in winter to prevent freezing injury. The optimum growth temperature is between 18-30 ℃. When the temperature is higher than 30 ℃, the growth will be inhibited. Therefore, ventilation and cooling are needed to increase the number of water spraying to increase the relative humidity of the air. Generally, the humidity should be kept at about 50% during the growth period to meet the demand. When the temperature is higher than 25 ℃, the air humidity should be increased to about 70%. When the temperature is lower than 15 ℃, the frequency of watering should be reduced, and the basin soil should be dry and wet alternately. It can tolerate short-term waterlogging, but long-term waterlogging is easy to rot roots and cause plant death.
At the end of spring, jinzuanlvrong has entered the peak growth period, and it needs to supplement nitrogen fertilizer to make it grow rapidly and restore its vitality. The principle of fertilizing is to apply fertilizer thinly and frequently, and not to apply enough fertilizer at one time. If we can use thin light fertilizer water instead of clear water to irrigate the basin soil in the growth period, the growth will be better. In autumn, we should control the amount of nitrogen fertilizer, otherwise it is not conducive to overwintering, petiole will become longer, and plant shape can not be effectively controlled. When the temperature is lower than 20 ℃ in winter, fertilization should be stopped.
Cultivation method of jinzuanman green velvet propagation method of jinzuanman green velvet: jinzuanman green velvet mostly adopts cutting, sowing and splitting method, and it is better to adopt cutting and splitting method in family, and the operation is relatively simple.
When cutting propagation, the best time is from May to September. The stems with strong growth and long branches should be cut and directly inserted into the clean river sand and placed in the semi shade. The air humidity should be kept at a high level, and the temperature should be about 25 ℃. The roots can take place in 20-25 days.
When there is a small plant at the base of the old plant for ramet propagation, it can be carried out in combination with changing soil and pots. The small plant should be carefully separated from the old plant, so as not to damage the old plant and root as much as possible. When the new lateral plant is about 15 cm in length, it can be cut off and replanted with air.
The common diseases of jinzuanman green velvet are leaf spot, anthracnose and so on, which can be controlled by wettable powder such as carbendazim, thiophanate methyl, and mancozeb. If the leaves are yellow, withered and scorched, they need to be pruned in time to reduce the loss of nutrients. The main pests are red spider and scale insects, which can be controlled by spraying special insecticides. In addition, the control of red spider can be prevented by increasing air humidity and strengthening ventilation to prevent scale insects.
