Due to the variety of flowers and flowers, and the prolonged flowering period, Du Fu has been planting land in squares and roads in recent years, which has played a significant role in landscaping. However, it is also vulnerable to dozens of diseases and insect pests and lose its ornamental nature. Over the years, many units have spent a lot of manpower and material resources to prevent and control, but they often fail to achieve good results. The main reason for this is that the main reason is not really to prevent it. Through three years of investigation and research, we have explored some methods for comprehensive prevention and control. 2. Soil Azalea prefers well-drained acidic soils. However, due to the use of concrete as roads and paving for gardens and landscapes, the soil of the azaleas is hardened and the alkalinity is serious. Therefore, the soil in the planting areas must be replaced and added. A certain amount of peat soil. 3. The rhododendron planted rhododendron is most suitable for planting in early spring or late autumn. If it is planted in other seasons, an arbor must be erected. When planting, the root system and soil must be made uniform, but it should not be too tight, and the soil surface near the rhizome should be curved. State, this will not only protect the superficial roots of the plant from freezing cold, but also contribute to drainage. 4. Du Fu's daily management 4.1 Watering Rhododendrons require that the dryness and humidity of the soil be moist and not wet. In the spring and autumn season, rhododendrons planted on open fields can be poured once every two to three days. During the hot summer season, water is poured at least once a day. Daily watering, should not use alkaline water, watering should also pay attention to the water temperature should not be too cold, especially in hot summer, with cold water drenched, causing a sudden drop in soil temperature, affecting root water absorption, interfere with plant physiological balance. 4.2 The spray rhododendrons like the environment with high humidity, but some rhododendron gardens are built on both sides of the square and on the roads. The air flow is fast and relatively dry. Therefore, the rhododendron leaves must be sprayed with water or sprayed on the surrounding air. The air around the azalea garden remains moist and conducive to the growth of azaleas. 4. 3 Fertilization In the late winter and early spring of each year, it is best to apply some organic fertilizer to the azalea garden as a base fertilizer. After the azaleas flowered in April-May, they consumed a large amount of nutrients during the flowering period. With the sprouting of leaf buds, the new shoots grew longer and they could be chased once every 15 days. After entering into the volcano, most shoots have stopped growing. At this time, the high temperature season, the physiological activity is weakened, and fertilizer can no longer be applied. After the autumn, the climate gradually cools, and when there is autumn rain, the temperature and humidity are suitable for the growth of rhododendrons. At this time, it can be used as a top-dressing fertilizer, which is generally not suitable for fertilization after winter. 4.4 Pruning Pruning and pruning is an important measure in the daily maintenance and management work. It can regulate growth and development, so that the growing trend is strong. The daily pruning needs to cut off a few diseased branches and delicate old branches, and remove some dense shoots in combination with the canopy form to increase ventilation and light transmission, which is conducive to plant growth. For the Dujuan Garden to be checked frequently and found dead branches and diseased branches should be cleared in time to reduce the spread of pests and diseases in the cuckoo.
