Planting conditions and area of mango

First, the temperature conditions The most suitable temperature for mango growth is 20-35℃, and it will stop growing below 15℃. Young mango trees have certain freezing damage at 2-5℃, and when the temperature is lower than 2℃, mango trees are seriously frozen or die. When the temperature is lower than 20℃, mango anthers can't crack and loose pollen, and pollen grains can't germinate below 15℃. When the temperature is lower than 10℃, the leaves and inflorescences of mango will stop growing, and the nearly mature mango fruit will suffer from cold damage, and when the temperature is lower than 3℃, it will be seriously damaged. It is suggested that mango should be planted in the frost-free period with the annual average temperature of 2 1 ~ 27℃ and the highest average temperature of Leng Yue 12℃. Second, soil conditions Mango trees are not strict with soil requirements. It is suggested that the soil with deep soil layer, underground water level below 3m, good drainage, alkaline or weakly alkaline soil is not suitable for planting mango, and loam or sandy loam is easy to cause nutrient deficiency (potassium, zinc, magnesium, etc. ), and the soil PH should be between 4.4 and 7.5. ). Third, light conditions Mango is a positive tree species. In the case of sufficient lighting conditions, there are many flowers and fruits, beautiful appearance, high sugar content, good quality and good storage and transportation resistance. For example, the red awn variety is lighter or less obvious when the light is insufficient. Generally, sufficient sunshine is beneficial to the growth and fruiting of mango. In the canopy with poor ventilation and light transmission, it blooms early, bears more fruits, has good quality, and has less fruits and poor quality. 4. Water conditions Mango trees need enough water to support the growth, flowering and fruit development of branches. However, in the flowering and shoot growth period of mango, continuous rainfall, heavy fog or high air humidity are easy to cause diseases, affect pollination, and cause dead leaves, flowers and fruits. Rainy weather during mango fruit development is easy to induce soot disease and anthracnose, and affect the appearance of fruit, reduce quality, delay ripening, and the fruit is not resistant to storage and transportation after harvest. Mango can achieve high and stable yield when the rainfall reaches 750 mm. When it is rainy in flowering and fruit-setting period, big dew will seriously drop flowers and fruits, and uneven humidity or excessive rainfall will cause fruit cracking, but drought in autumn and winter is beneficial to flower bud differentiation and early flowering.
