Longan is a sun loving crop. Sufficient light plays an important role in the normal growth of longan. With strong light intensity, the stem will grow stronger, which is conducive to the accumulation and absorption of nutrients. The branches and leaves will also grow more luxuriantly, and the photosynthesis will be very vigorous. In this way, there will be more nutrients accumulated in the fruit and high sweetness. And the yield and quality of fruits will be improved. In addition, areas with deep and fertile soil and high organic matter content must be selected for planting longan. 1、 Longan likes Yang or Yin. Longan is a kind of Yang loving crop. Sufficient light is an essential condition for the normal growth of longan. When the light intensity is insufficient or the sunshine duration is insufficient, it obviously shows that the fruit development and autumn shoot growth are slow. In the flowering period, if there is too little light and more cloudy and rainy weather, it will affect pollination and fertilization. In this way, the fruit setting rate or fruit quality of longan will be greatly reduced. If it is planted in coastal areas, it may be done a lot in summer and autumn due to typhoons. Therefore, it is important to select the location of fruit forests and set up protective forests. 2、 What soil does longan like 1 Soil: it is best to plant longan in the soil with deep soil layer, high content of organic matter and good ability of water and fertilizer conservation. The pH of the best soil is maintained between 5-6, preferably red soil and sandy loam.
2. Plot: it is better to plant in the mountain without freezing injury and with low wind force. The slope of the mountain is better below 15 degrees, which is convenient for irrigation.
3. Fertility: the soil layer for planting longan must have sufficient fertility. Before planting, green fertilizer, organic fertilizer and quicklime shall be mixed, and the compost after maturity shall be fully diluted and used as the base fertilizer in the soil. This soil layer is fertile and deep, rich in organic matter and strong air permeability, which can lay a good foundation for the growth of longan. （LongYanXiYinHaiShiXiYang）
