Maple tree is a common streetscape tree species in my country. Its beautiful appearance and rich nutritional value are deeply loved by people. However, during the growth of maple trees, some disease problems will be encountered, the most common of which is maple leaf roll disease. In order to protect the health of maple trees, we need to understand the prevention and control methods of maple leaf roll.
1. Understand the maple leaf roll disease 2. The harm of the disease 3. The symptoms and characteristics of the disease 4. The impact of environmental factors on the disease 5. Regular inspections to discover early diseases 6. Strengthen the nutritional management of maple trees 7. Maintain the growing environment of maple trees 8. Select disease-resistant varieties for planting 9. Remove the source and sick bodies 10. Spray spraying in winter 11. Cut off dead branches in spring 12. Spray spraying in summer 13. Remove diseased leaves in autumn 14. Strengthen the maintenance and management of maple trees 15. Scientifically control and control maple leaf roll disease 1. Understand maple leaf roll disease: Maple leaf roll disease is caused by mold infection A disease, mainly occurs in spring and autumn. Mold forms gray-white fluff on maple leaves and gradually deforms the leaves.
2. The harm of diseases: Maple leaf rolling will affect the growth and development of maple trees, causing the maple to lose its beautiful appearance and reduce its value. In addition, the disease can reduce the disease resistance of maple trees, making them more vulnerable to other diseases.
3. Symptoms and characteristics of the disease: Maple leaf roll disease is mainly manifested as leaf deformity, pale color, and even death. In severe cases, the blades will curl from the center to take on a cone or arc shape.
4. Impact of environmental factors on diseases: Maple leaf roll disease is mainly affected by environmental factors, such as temperature, humidity, light, etc. Under conditions of high temperature and high humidity, diseases will occur more easily.
5. Regular inspections to discover early diseases: In order to effectively prevent and control maple leaf roll disease, we need to regularly inspect maple trees and detect and deal with early diseases in a timely manner. Once a disease is discovered, corresponding prevention and control measures should be taken.
6. Strengthening nutritional management of maple trees: Maple leaf roll disease is closely related to the nutritional status of maple trees. In order to prevent the occurrence of diseases, we should strengthen the nutritional management of maple trees to ensure adequate water and nutrient supply.
7. Maintain the growth environment of maple trees: Maple leaf roll disease is also related to the growth environment of maple trees. In order to maintain the growing environment of maple trees, we should prune branches and remove weeds and garbage in a timely manner.
8. Select disease-resistant varieties for planting: In order to reduce the risk of maple leaf roll disease, we should choose disease-resistant varieties for planting. These varieties are more resistant to diseases and are easier to grow and develop.
9. Eliminate the source of disease and disabled bodies: In order to prevent the spread of maple leaf roll disease, we should eliminate the source of disease and disabled bodies. Once rolling maple leaves are found, leaves, branches and dead leaves should be removed in time.
10. Winter spraying prevention and control: Winter is the best time to control maple leaf rolling. In winter, we can spray with pesticides to kill mold and kill viruses.
11. Cut off dead branches in spring: Spring is a critical period to prevent and control maple leaf roll. In spring, we can cut off dead branches and promote the growth and development of new buds.
12. Summer spraying control: Summer is also an important period to control maple leaf rolls. In summer, we can spray with pesticides to protect maple trees from disease.
13. Remove diseased leaves in autumn: Autumn is the period of high incidence of maple leaf roll disease. In order to prevent the spread of diseases, we should remove diseased leaves and sick bodies in time to keep the growing environment of maple trees clean and sanitary.
14. Strengthen the maintenance and management of maple trees: The maintenance and management of maple trees is also an important measure to prevent and control maple leaf roll disease. We should prune branches in time, remove weeds and garbage, etc., to keep the maple tree growing environment healthy and hygienic.
15. Through scientific and reasonable prevention and control measures, we can effectively prevent and control maple leaf roll disease, protect the growth and development of maple trees, and contribute to the city's greening cause.
