Why do the leaves of the rich tree turn yellow?

Why do the leaves of the rich tree turn yellow? Please tell us the reason why the leaves of the rich tree are yellowing. Please refer to the following introduction: 1. The ambient temperature is low. If your rich tree indoor ambient temperature is maintained above 15 ℃, the temperature below 18 ℃ rich tree will stop growing, rich tree originated in tropical America, widely distributed in Southeast Asia, sexual preference for warm and humid environment, require growth temperature of 18-30 ℃, not cold-resistant, spring in the lunar calendar at the end of March or the beginning of May out of the room, avoid room temperature less than 8 ℃, otherwise there will be frost injury, light deciduous, heavy death. 2. Lack of light. Wealth trees like the light but avoid direct sunlight, and keep it indoors where there is scattered light, while it is better to put it indoors in winter. Starting from late April, choose a sunny and warm noon, move the basin out of the outdoor or balcony, directly see the sun for 1-2 hours, and gradually extend the time until full light management. in the outdoor full light environment, the leaf node is short, the leaf is wide, the color is dark green, the crown is plump, and the base of the stem is fat. In low light for a long time, the branches are thin, the petiole is drooping, and the leaves are light green. No matter under what environment, do not suddenly change the location, change the location should be a gradual adaptation process, such as suddenly transfer the plant from the shade to the sunny place, will make the leaves burn, scorched edge, affect the appearance. Long-term lack of light, the plant is easy to appear yellow leaves and accompanied by shedding. 3. The moisture is too wet. Rich trees do not have high requirements for water and should not be watered too much to prevent stagnant water in the basin soil, causing root rot and plant death. Water is watered once indoors in summer and every 5-10 days in spring and autumn, but it is not an absolute interval. It should be grasped flexibly and should be based on the principle of "seeing dry and wet" in basin soil. If the water is too wet, there will be waterlogging, yellow leaves, root rot and shedding. 4. Too much fertilizer. In the period of suitable temperature for growth, it should be fertilized regularly to ensure that the plant grows luxuriantly. Generally, thin fertilizer is applied once in about 20 days, but less nitrogen fertilizer is applied to avoid overgrowth. When changing the basin, we should not only replace the new nutrient soil, but also add rotten base fertilizer to make it thrive. If too much fertilizer is applied, or if the fertilizer is not rotten, the roots will burn, yellow leaves will occur and fall off. 5. There is thick dust on the leaves. The leaf surface such as dust is too thick, which not only affects the appearance, but also affects the respiration and photosynthesis of the plant. Seriously affect the healthy growth of the plant, the dust on the leaf surface should be sprayed clean in time, or wipe clean with a soft cloth. 6. Diseases and insect pests. The rich tree has strong resistance and less diseases and insect pests, so it can be controlled by spraying carbendazim and carbendazim in summer. 7. An error occurred in the soil exchange operation. Generally speaking, the soil change should hurt the roots less, and the added matrix should be aseptic, breathable, fertile, slightly acidic, and fill the basin soil without leaving gaps. If there are gaps, the plants will be irrigated with more water, or the phenomenon of water shortage will occur. Serious yellow leaves will fall off and branches will atrophy.
