Last Updated: 2024/11/05, For every 1000 kilograms of fresh mango, it takes 1.74 kilograms of NRU, 1.74 kilograms of P2O5:0.23, and one kilogram of K2O:2.0. Potassium is the most needed, followed by nitrogen and phosphorus. In production, nitrogen, phosphorus and potassium fertilizers are generally applied according to N:P2O5:K2O=1:0.5:0.5~1, but mangoes with different tree ages, different regions and different yield levels.

The irrigation of mango fruit trees mainly has two periods: the first period is after fruit harvest and pruning, when it is in a period of drought, irrigation should be combined with post-fruit fertilizer to promote the extraction of autumn shoots and cultivate healthy fruit mother branches in the coming year. The second period is the fruit development period, in which fruit development, cell division and fruit expansion need a lot of water. At this time, irrigation can fully meet the needs of fruit growth and development and increase yield. Water should be irrigated 2-3 times a month according to weather conditions. The key points of fertilization for fruit trees are as follows: one is to apply post-fruit fertilizer (June-early July): post-fruit fertilizer is the focus of fertilization throughout the year, accounting for 70-80% of the total amount of fertilizer applied throughout the year. The main purpose is to promote autumn shoots and restore growth, so as to lay a good foundation for next year's results. Mainly available nitrogen fertilizer and organic fertilizer, 30-50 kg organic fertilizer per plant, 1-1.5 kg urea and 0.5 kg compound fertilizer were applied after fruit picking and pruning. The second is to apply flower-promoting fertilizer (September-October): the normal flower bud differentiation of mango is usually from November to December, and the flower bud differentiation promoted by chemicals can be earlier than October. Therefore, the flower-promoting fertilizer should be applied before the end of the rainy season, mainly potash fertilizer, 1-1.5 kg potassium nitrate per plant. Third, thanks to flower fertilizer: mango flowering will cause a lot of nutrient consumption, should be applied in the flower, urea or potassium nitrate 0.5-1 kg per plant, urea or potassium nitrate mixed with water into 0.5-1% fertilizer spray leaves, extra-root topdressing, supplement nutrients. The fourth is to apply strong fruit fertilizer: when the mango blossoms about 30 days, the young fruit grows rapidly, in order to reduce fruit drop, each plant is applied 0.5-1 kg urea and potassium nitrate, or other foliar fertilizer.
