management points: light, avoid strong light, the suitable growth temperature is 2℃~3℃, and the growth starts at 1℃; Soil, the requirements are not strict, and it is better to grow in sandy loam rich in humus and well drained. Potted plants are mostly mixed with peat and perlite to prepare nutritious soil. It should be placed in a semi-shady place and avoid direct sunlight in summer. Always keep the soil moist during the growth period, avoid being too dry, and put it away from the heating and air conditioning outlets. Prevent leaf yellowing, pests and diseases. Diseases are mainly caused by maintenance or environmental discomfort, which can generally be prevented through good maintenance management; For pests such as Starscream, spraying water frequently and wiping leaves can effectively prevent them. Spraying special killing agents can be used for prevention and control. Common leaf problems and causes The main causes of leaf yellowing of Golden Diamond Velvet are temperature discomfort, low humidity, uncomfortable illumination, excessive fertilization, frequent watering, and pests and diseases. Spring-feathered plants are flourishing, with large and strange leaves, green and shiny leaves and strong shade tolerance. It is one of the most widely used indoor foliage plants in families and public places. Potted plants can be placed in spacious places such as living rooms and lobbies, or hydroponic plants can be placed on desks and windowsills. Spring feather, with large leaves, petiole with leaves up to more than 1 meter long, flowering mostly in spring, showing Buddha's bud shape, with low ornamental value, mainly for leaf viewing. The requirements for soil are not strict, but the slightly acidic soil with loose fertility and good drainage grows best. Spring feather is native to the tropical rain forest of Brazil in South America. It likes warm, humid and semi-cloudy environment, and does not require strict light, but it cannot tolerate long-term shade environment, otherwise the leaves will become pale, the petiole will become longer, and the leaves will droop and the ornamental value will be reduced. I am also afraid of strong direct light. After strong light irradiation, the leaves are prone to dry tips, scorched edges, albinism and loss of luster, so it is best to maintain them with semi-shade or scattered light. In winter, you can take care of it with sufficient light to make it safely overwinter. Spring feather is a tropical plant, which is not tolerant to cold and low temperature. It is best to keep the temperature above 1℃ in winter to prevent freezing injury. The optimum growth temperature is between 18-3℃. When the temperature is higher than 3℃, the growth will be inhibited. It is necessary to ventilate and cool down and increase the number of water sprays to increase the relative humidity of the air. Generally, it is necessary to maintain the humidity of about 5% during the growth period to meet the demand. When the temperature is higher than 25℃, it is necessary to increase the air humidity to about 7%. Spring feather leaves are large and thin, which requires high water content. During the growth cycle, it is necessary to keep the basin soil moist, especially during the high temperature period in summer. When the temperature is lower than 15℃, it is necessary to reduce the number of watering, and the basin soil should be wet and dry alternately. It can tolerate short-term waterlogging, but long-term waterlogging is easy to rot the root system and lead to plant death. At the end of spring, the spring feather has entered a period of vigorous growth, so it needs to be supplemented with nitrogen fertilizer to make it grow rapidly and restore its vitality. Fertilization is based on the principle of thin fertilizer and diligent application, and it is not allowed to cause fertilizer damage by applying enough at one time. If we can use thin light fat water instead of clear water to irrigate the basin soil during the growth period, the growth will be better. After entering autumn, it is necessary to control the application amount of nitrogen fertilizer, otherwise it will not be conducive to overwintering, petiole will also become longer, and plant shape will not be effectively controlled. When the temperature is below 2℃ in winter, fertilization should be stopped. The propagation methods of spring feathers are mostly cutting, sowing and dividing plants, and it is best to use cutting and dividing plants in the family, which is relatively simple to operate. When cutting propagation, it is advisable to take May-September, cut off the stems with strong growth and long branches, directly insert them into clean river sand and place them in the semi-shade, keep high air humidity, and the temperature is about 25℃, so that they can take root in 2-25 days. When ramet propagation needs to produce small plants at the base of old plants, it can be combined with changing soil and pots, and the small plants should be carefully separated from the old plants so as not to hurt the old plants or roots as much as possible. You can also pick the side plant before lifting it, which can not only dwarf the plant, but also give birth to more side plants. When the new side plant is about 15 cm, cut it with aerial roots and plant it again.
