What kind of flower is this and how to care for it? Thank you, omnipotent netizens.

The green emperor is full of green Rong.

Temperature: Green Emperor likes warm environment and is afraid of cold. The suitable temperature is between 20-30℃, and the temperature in winter should not be lower than 10℃, otherwise it will be vulnerable to freezing injury and lead to death, and it will start to grow around 13℃. Heating equipment is needed for winter maintenance. If heating facilities are not used, double insulation facilities can be used. In winter, when the temperature drops to 22-24℃ in the afternoon, the shed should be closed in time (generally in the north of the shed, and a certain space can be reserved in the south of the shed to facilitate the air circulation in the shed and prevent the humidity in the shed from being too high). If you plant in a simple shed in summer, the film should be uncovered in sunny days, and there are two layers of shading nets with a density of 75% on the roof, which can ventilate and cool down. However, in continuous rainy days, film should be covered to prevent root rot and stem rot caused by long-term wet substrate in the basin due to too much rain. In summer, shading and ventilation can be strengthened, and foliar water and surface water can be supplemented to achieve the purpose of cooling. At the same time, long-distance multi-span greenhouses should not be used, but independent single ceiling should be used.

Lighting: Green Emperor likes astigmatism. Too strong lighting will make the leaves "dry and wrinkle". Sex likes warm and humid semi-cloudy environment, and direct sunlight is forbidden in summer, otherwise the leaves will be burned. It is more appropriate to control the illuminance at around 15000 Lux. If you plant in a simple shed, you can spray air and water on the ground in summer morning (about 10: 00) to increase the air humidity and reduce the leaf surface temperature. Try to keep a ventilated, warm and semi-cool environment. In summer, there is too much shade in the greenhouse, the light is lower than 15000 lux, and the leaves and petioles of plants are drooping and not upright, which is easy to grow white. With the decrease of temperature in winter and early spring, the light can be gradually increased and controlled at 20,000-30,000 lux. In short, when the temperature is high, the light is lower, and when the temperature is low, the light is stronger within the allowable range. If you plant in a simple shed, you only plant seedlings for 1-2 months, and the roof of the shed should be covered with film in summer, otherwise it will be easy to get sick in rainy days, leading to leaf rot and plant death.

Base fertilizer: using Austrian green controlled release fertilizer as base fertilizer, when the pot position is kept at 9- 12cm, about 3g can be put in each pot; Replace it with a pot of 25-35cm, and each pot can hold about 10g. The first stage of fertilizer and water management: in spring (March-April), the climate is mild and the temperature is relatively low. Generally, fertilizer and water are poured once every 4-7 days, and the concentration of N is 200mg. (fertilizer concentration = fertilizer dosage (kg)x nitrogen content X 1000000/ solvent weight (kg); The temperature is relatively high in summer (May-September). Generally, it is watered once every 4-5 days. The concentration of fertilizer solution should be low, and the concentration of N should be controlled at 150-200mg. In the high temperature season from July to August, the concentration of fertilizer can be thinner. Dry in autumn, please refer to fertilization in spring. In winter, the temperature is low and the evaporation is small. Generally, it can only be poured semi-thoroughly, and the fertilizer concentration is N250-300mg.
