Mangoes are known as the "Tropical Fruit King" and are rich in nutrients that humans need. Mango trees are fast growing, resulting in high yields, long harvesting periods, low requirements for cultivation conditions, and high economic returns. Mango cultivation of high yield, we must first select a good variety, seedlings grafted survival, the timely expansion of deep hole expansion, pest and disease prevention and other management. Scientifically and rationally applying fertilization is an important link in the entire tree age cycle, which is related to high yield and fruit quality. The main nutrients absorbed by mango growth include nitrogen, phosphorus, potassium, magnesium, manganese, boron, and zinc. The ratio of nitrogen, phosphorus, and potassium required is 1.2:0.12:1. Precautions: 1. The young mango tree has a small root system, the number of fibrous roots is small, and the distribution is shallow. Therefore, the fertilizer must be fertilized and applied thinly. Apply fertilizer during drought. 2, fertilization should not be close to the trunk of the site, but the crown outside the drip line, uniform distribution of acupuncture points good effect. 3, the amount of fertilizer can be adjusted according to the soil fertility situation around the situation. 4, young mango trees can be increased by a little bit of nitrogen, the results of the tree in the application of some organic fertilizer is better.
