Navel orange is a sun loving crop. Appropriate light intensity and sufficient light duration can make them grow luxuriant and thick branches and leaves. In this way, the efficiency of photosynthesis is higher, the accumulation of organic matter is more, and the sweetness and size of navel orange are higher. In this way, the quality and yield of the whole navel orange tree will be improved. When the light condition is insufficient, the germination rate and branching rate of navel orange tree will decrease. 1、 Navel orange likes yin or yang. Orange is a light loving crop. The growth of navel orange has strict requirements for light, and the best annual average light time can reach 1200 hours. When the light conditions are good, the branches of navel orange tree are relatively strong, and its leaves are large and thick, which can transport and accumulate nutrients well. When the light conditions are met, the photosynthesis of leaves is vigorous, inorganic elements are transformed into organic matter, and more nutrients and sweetness are accumulated in navel orange. 2、 How to plant and manage Navel Orange 1 Soil: yellow soil mixed with gravel and pure yellow soil are selected to plant navel orange, and the soil pH is weakly acidic. When choosing the garden for planting navel orange, ensure that the soil and water source are not polluted, and choose the gentle slope sealed to the sun.
2. Temperature: navel orange is highly inclusive of temperature. The best planting temperature is 21 ℃ - 25 ℃. Generally, the temperature can be controlled at 15 ℃ - 30 ℃.
3. Pruning: the purpose of plastic pruning is to ensure that the plant has a more appropriate tree structure. In addition, the branches and leaves should be pruned in time, so that the light can shine through the upper branches and leaves, so as to ensure that each branch and leaf can carry out good photosynthesis and make navel orange high-quality and high-yield. Make effective use of light energy and space to make navel orange trees premature fruit and improve yield and quality. （QiChengXiYinHaiShiXiYang）
