The leaves are important organs for photosynthesis of plants. 90% of all dry matter in fruit trees comes from photosynthetic products, and only 10% from minerals in soil. Through the chlorophyll in the leaves of plants, the process of synthesizing organic matter by the absorption of carbon dioxide in the air and the water absorbed by the roots is called photosynthesis.
The number of photosynthetic products is closely related to the leaf area coefficient per unit area and the dynamic change of the leaf area in the middle of the year. In general orchards, the leaf area coefficient must be kept within the range of 3-4. Most of the fruit trees sprout 10-14 days after the sprouting, but the degree of fatigue will only increase. A net output of only 1/2 hour has begun.
With the increase of leaf age and senescence, the photosynthetic intensity decreases. Therefore, in order to establish an effective and effective leaf in the early stage and improve the photosynthetic efficiency of the leaves, the tree nutrient should be strengthened and high-quality leaves (large, green, thick and shiny leaves) should be cultivated. By pruning to ensure adequate light, pay attention to pest control, can extend the life of leaves and photosynthesis time.
The quality of fruit trees is mainly based on the accumulation and storage of organic substances. Therefore, the larger the leaf area, the more the organic nutrients produced by photosynthesis and the more flower buds are formed. Therefore, when picking fruit, care should be taken to protect the leaves. After harvesting, take measures to protect the leaves from pests and diseases. Spray the fungicides and insecticides on them in time to prevent and control them.
