After cutting off the dead leaves, it is necessary to replenish water and chemical fertilizer to the roots in time, which can not only ensure the survival of the trees, but also improve the yield of citrus and make the fruits delicious.
The main branches of young citrus trees should be 20-30 cm. When young citrus trees sprout summer shoots, they should be cut off 30-40 cm from the ground to promote them to sprout new branches. When 3-5 summer buds germinate, autumn buds can germinate by coring, which is a secondary branch.
Grafting time of citrus
1. Citrus can be grafted in spring, summer and autumn, and September-10 is the best in autumn. Look at the local weather forecast before grafting. Grafting should be carried out in cloudy or cloudy weather.
2. Don't choose sunny or rainy days for grafting, because high temperature and sunlight will lead to the evaporation of scion juice and reduce the survival rate of grafting; Rain is not conducive to the healing of marriage interface, and may also breed diseases.
3. The suitable grafting temperature is 65438 05-20℃. The temperature is too low, the tree is inactive and the juice flows slowly, which is not conducive to the healing of grafting interface. If the temperature is too high, the air humidity will decrease, which will slow down the wound healing and facilitate the invasion of germs into the wound.
