1. Fertilization: Fertilization can be started one month after planting. In the second or third year, it is mainly to increase the amount of roots, promote shoots, and enhance shoots. Mastering "one shoot with two fertilizers" or "one shoot with three fertilizers", that is, applying a quick-acting fertilizer based on nitrogen fertilizer when the shoots top buds sprout, prompting the rapid growth of new shoots and long leaves; when the growth of new shoots basically stops, leaf color From red to green, the second fertilization was applied to prompt the shoots to turn green quickly and thicken the branches. After the green shoots are turned green, the third fertilizer is applied to accelerate the aging of the new shoots. In the first year after planting, the roots were small, and each plant used 25 grams of compound fertilizer, 15 grams of urea, 10 grams of potassium chloride, and 50 grams of superphosphate. The saplings have a small root system and weak fertilizer absorption capacity. Each year, 5-6 times of foliar fertilizers can be sprayed. 2. Irrigation and drainage: Moisture is an important part of the litchi tree. Juvenile lychee roots are less and shallow, and are affected by the changes of surface soil moisture. Under conditions of soil drought and atmospheric drying, watering and moisturizing should be paid attention to. In the rainy season, water should be prevented from planting holes, and sinking plants should be properly raised to facilitate normal growth. Litchi mycorrhiza good air, loose soil ventilation, conducive to root growth and development. Young orchards generally weed the soil 5-6 times a year. Summer and autumn are hot and humid, and weeds grow rapidly. The number of weeding in weeding should be more, the ground temperature in spring is lower, the surface is dry in winter, the rainfall is small, weeds grow more slowly, and the number of tillage is less. The main contents of soil improvement in Litchi Garden include deep-ripening and ripening, thickening soil layers and increasing organic matter.
