Firstly, the causes of yellowing of the leaves of the rich tree are mainly due to improper watering, insufficient light, pests and diseases, thick dust on the leaves, excessive fertilizer, excessive moisture, hot and high temperature, tight ventilation, low ambient temperature, and alkaline soil and water. The following small series for everyone to specifically analyze the causes of the yellowing of the leaves of the rich tree and the solution. Linyi Fertilizer Network Copyright
1. Improper watering: The fortune tree is warm and humid, and the potting soil is suitable for moistening. However, the indoor potting is generally not poured or poured, and the pouring is poured. Because, if it is not poured during watering, pouring it on wet and dry will affect the absorption of nutrients, resulting in dull and dull leaf color, and gradually fall off from the bottom up. In this case, a small amount of water is needed and water is often sprayed to allow it to gradually recover before switching to normal watering. Linyi Fertilizer Network Copyright
2, light discomfort: rich trees like light, but not resistant to strong direct light, with half-negative or scattered light is appropriate, only good winter conditions require good light conditions to grow well. From the end of April, you can choose the warm and noon, move the pot out of the outdoor or balcony, directly see the sun for 1-2 hours, and gradually extend the time, there will be a good breeding effect. Long-term in the shade or in the dark, there will be yellowing and defoliation of the leaves, and severe cases will die. Linyi Fertilizer Network Copyright
3, pest control: Leaf spot disease is a common disease of the tree, the symptoms are that a few spots appear first, and then the spots gradually expand to the entire blade, and fall off, can be sprayed with garlic juice. In terms of pests, there are mainly red spiders and scale insects. The red spider is small and has a body length of less than 1 mm. It can be effectively prevented by using chlorpyrifos, ketone and dicofol. Individuals of scale insects vary in type and color, but they have a common feature, that is, they are round or elliptical, generally do not move, sucking juice close to the stem or petiole of the plant, and wiping it with a cloth strip when it is small. However, because the scale insects will die when they leave the plant, they can be sprayed with a 0.2% solution of Fengyoujing and washing powder for prevention and treatment.

4, too much fertilizer: In general, in the warm-up period of the fortune tree growth, should be applied regularly to ensure that the plant flourishes, generally 20 days or so to apply a thin fertilizer, the basin should be added with decomposed base fertilizer. If the fertilizer is applied too much, or the applied fertilizer is not decomposed, it will lead to the burning of the tree, and the yellowing of the leaves will occur.

5, the leaves have dust: If the leaf surface dust is too thick, not only affects the appearance, but also affects the plant's breathing and photosynthesis, resulting in yellowing of the leaves of the tree. Wipe the dust cleanly in time. Linyi Fertilizer Network Copyright
6, soil replacement operation error: when changing the soil, the wrong operation will also cause the leaves of the rich tree to yellow. When changing the soil for the rich tree, try to minimize the root damage. The added substrate should be sterile, breathable, fertile, and acidic. Also fill the soil without leaving voids. If there are gaps, plant more water. Water, water shortage will still occur, resulting in yellow leaves. Linyi Fertilizer Network Copyright
7, low ambient temperature: rich tree-like warm warm environment, its growth temperature is 20-30 ° C, the temperature is lower than 18 ° C, the tree will stop growing, the temperature can be adjusted as low as 10 ° C, but the temperature can not be low At 5 ° C, otherwise frost damage will occur, light yellow leaves scattered, and severe death.

8. Hot and high temperature: For the rich and warm environment of the rich and humid environment, if it is exposed to high temperature, the transpiration of the plant is too strong, and the water nutrients in the roots are in short supply. It is easy to cause the leaf tip to dry or the yellow leaves to fall off. The shade. Linyi Fertilizer Network Copyright
9, dense ventilation: If the leaves of the rich tree grow too lush, plus long-term untrimmed, so that the light inside the lychee leaves is insufficient, it is easy to cause the yellowing of the leaves to fall off, should be strengthened in time to make it ventilated and transparent.

10 Soil and water alkalinity: Most soils and waters in the north contain more salt and alkali, and it is not suitable for planting acid trees. Because of the lack of iron in the soil, the leaves of the tree will gradually turn yellow. . At the time of planting, it is necessary to pay attention to the use of acid soil, and often water and fertilizer during the growth period. Linyi Fertilizer Network Copyright
