1, environment selection
For potted bergamot, it is better to use sandy soil rich in humus, fertile and loose, and acidic. Usually, it is planted with weathered pond mud or rotten leaves to keep acidic soil, and it can also be cultivated with fertilizer prepared from decomposed chicken manure, garden soil and river sand.
2. Water and fertilizer management
When the fingered citron grows vigorously, it is necessary to strengthen watering, especially in the high temperature environment in summer, and to spray water to improve the humidity of the fingered citron growing environment. After autumn, watering should be reduced, and watering should not be too much during the flowering and fruiting period. The fertilization of fingered citron should be timely, and/kloc-0 thin cake fertilizer should be applied once a week, and cake fertilizer solution should be applied during the flowering and fruiting period, and a small amount of phosphorus and potassium fertilizer should be applied.
3, pruning
Chaenomeles should keep 3-5 fruiting branches to promote the formation of crown, and subtract 2/5 from the long branches in summer to let it produce fruiting branches. New shoots sprouted in autumn should be properly reserved for the next year's fruit. All the fruits that are not easy to set should be removed. There are too many fruits in bergamot, so it is necessary to remove the diseased fruits and weak fruits in time and supplement the nutrients to the fruits with good quality.
4, pest control
Fingered citron is very delicate and prone to diseases and insect pests such as anthracnose, bituminous coal disease and scale insects. When diseases and insect pests are found, they should be prevented in time. Pay attention to strengthen management and keep the trees clean and hygienic. Regular spraying of Bordeaux mixture can effectively control pests and diseases.
