2. The temperature of Liriodendron chinense should be kept above 65438 05℃ at the initial stage of hydroponics. Usually, white callus begins to form at the cut of Liriodendron branches after soaking in water 10 days, and quickly differentiates from these places to form adventitious roots. In about 45 days, the branches of Liriodendron planted in the water will give birth to roots more than 6 cm long and grow white root hairs, which can be managed normally.
3. Root washing method: carefully remove the cultivated Liriodendron from the soil, clean the soil at the root of Liriodendron, and plant it in a transparent glass bottle filled with clear water (tap water needs to be stored for 2-3 days). In the early stage of Liriodendron hydroponics, water should be changed 1 time every 2 or 3 days, and the temperature should be kept above 15℃. Give Liriodendron hydroponics proper light, and Liriodendron will grow full green.
4. Changing water: The water of Liriodendron hydroponics needs to be changed once a week, and some hydroponic plant nutrient solution is added every time, which can make Liriodendron hydroponics grow better. The hydroponics of Liriodendron chinense should not be too high, and it should not be soaked in the trunk of Liriodendron chinense.
5. Temperature: The optimum growth temperature of Liriodendron chinense is 15-25℃, and it can grow above 30℃. The overwintering temperature should not be lower than 5℃, otherwise the leaves of Liriodendron will fall off.
6. Illumination: The growth of Liriodendron requires sufficient illumination, and sufficient sunlight can make the leaves of Liriodendron shine. Liriodendron is shade-tolerant, and its leaves can be dark green in semi-shade. However, for Liriodendron, it is still necessary to bask in the sun regularly, but in summer, it is necessary to avoid exposure to the hot sun.
7, pruning: Liriodendron grows faster, pay attention to plastic pruning.
