Watering: The amount of water should be properly controlled under the condition of low temperature in winter. If you use plastic containers, pay attention to drainage. To keep the soil moist, water it in time before it dries out, and then spray it on plants when the weather is dry. During the rainy season, water should be prevented from accumulating in the basin. Of course, if the soil in the basin is too dry, it will also cause the leaves to fall.
Lighting: after leaving the house, it should be placed in a semi-shady place. In summer, we should pay attention to shading the sun in time and don't let the hot sun shine directly. In addition, if Liriodendron chinense is kept indoors for a long time, if the ventilation is poor or the light is too dim, the leaves will fall off, which deserves the attention of breeders.
Temperature control:11/kloc-0 should be placed in a cold room at the beginning of October, and the temperature should not be lower than 5℃, otherwise the leaves will fall. It doesn't like hot and cold environment. If you suddenly switch from low temperature to high temperature, you will also lose a lot of leaves, and it is best to gradually heat up.
Fertilization: apply liquid fertilizer once every 1 ~ 2 weeks in the growing season. During May-September, 20% cake fertilizer was applied twice a month. For mosaic varieties, if there is more nitrogen fertilizer and weak light, the plaque on the leaves is not obvious.
Pruning: before going out in spring, turn over the basin and trim it properly. For plants with too high feet, pruning can be taken back to promote the germination of new buds.
Pathogen: In order to prevent the harm of leaf spot disease, Tobuzin or carbendazim can be used, and the diseased leaves must be cleaned and destroyed before spraying.
