Mangoes harvested before harvest

Before and after fruit harvesting, mangoes have many fruiting and high yields, and the nutrient level after the fruiting of the tree is in the lowest period of the year. If fertilizer is not applied in time, the tree vigor will be weak and it will be difficult to restore growth, affecting the cultivation of the parent branch and the results of the following year. And production. Before and after harvesting fruit, the fertilizer is the focus of fertilization. The amount of fertilizer used accounts for 60% to 80% of the whole year.

Mixing and spraying some foliar fertilizers containing high phosphorus and potassium. In addition, the harvest of fruit trees before the harvest 60 days, can inhibit the photorespiration of plants, increase the accumulation of photosynthetic products, improve quality and yield.

Fertilizer can be divided into two parts after mango harvesting: The first fertilization is generally completed in August, mainly quick-release fertilizer, the purpose is to restore the tree as soon as possible, germinating as soon as possible autumn shoots. Each tree fertilizer 0.5 ~ 1.0 kg, urea 0.3 ~ 0.5 kg. In the canopy drip line inside the shallow digging shallow groove, in case of dry weather, fertilization after fertilization. The second fertilization combined with deep turning to improve the soil, generally in mid-November to December, to farmer-based fertilizer, each plant maturity farmyard fertilizer 20 to 30 kg, 0.5 to 1 kg compound fertilizer, potash 0.3 to 0.5 kg, Increasing the application of fire mud 10-15 kg per plant can promote tree heading and flowering.
