Fertilizer is an indispensable part of mango growth period, and it has a very good effect on promoting the healthy growth of mango, improving mango quality and yield.

1, urge flower fertilizer.

One month before flowering is the mango flower bud differentiation period. Fertilization before flower bud differentiation can promote flower bud differentiation. Fertilizers should be based on quick-acting nitrogen and potassium fertilizers, and the dosage is about 20% of the annual dosage. Each plant is applied with 0.1-0.2 kg of urea and potassium sulfate. , Generally apply calcium magnesium magnesium fertilizer 1.6-1.8 kg per plant).

Can be combined with foliar fertilization, spray with 0.2-0.3% potassium dihydrogen phosphate solution, spray until the leaf surface is covered with water droplets, if it is not dripped, continuous spray 2-3 times, each spray interval is 7-10 days .

2. strong flower fertilizer.

The mango tree has a large amount of flowers and consumes a lot of nutrients. It is necessary to apply a quick-acting nitrogen fertilizer once during the flowering period. Zhuanghua fertilizer can use urea or compound fertilizer. Each plant is applied with 0.1-0.15 kg of urea or compound fertilizer. It can be combined with foliar spray of 0.1% borax and 0.2-0.3% potassium dihydrogen phosphate solution.

3. Strong fruit fertilizer.

April-May is a period of rapid fruit growth, and also a period of rapid growth in spring. At this time, insufficient nutrients can cause a lot of fruit drop. Nitrogen and potash fertilizers can be applied once according to the plant's extraction and results, to balance the nutrient requirements of branch growth and fruit development.

4. Fertilize mangoes before and after harvesting.

This application of fertilizer is mainly based on organic fertilizer, combined with quick-acting fertilizer. At this time, the green manure is vigorous and can be combined with deep digging holes. Under the leaf curtain of each tree, two fertilization ditches with a length of 120 cm, a width of 45 cm, and a depth of 60 cm are dug symmetrically, filled with green manure, and mixed with 15-20 kg Manure or compost, 0.5-1 kg superphosphate.
