What is the temperature requirement of mango planting area?

Mango likes high temperature, not cold-resistant, and it is more difficult to avoid drizzling cold weather during flowering. The effective temperature of mango growth is 15-35℃, and the optimum temperature is 24-27℃. Only when flowering is above 20℃ can pollination and fertilization be normal. When the temperature is lower than 20℃, the anther will not crack and the pollen will not germinate, which will affect the results. Small trees can freeze to death at -3℃, and big trees will be severely frostbitten. Therefore, the local temperature is the limit that determines the suitability of mango planting. According to some data, the northern boundary of mango introduction in China is 27 43' north latitude, but generally speaking, the Tropic of Cancer is the northern edge of mango economic cultivation in China. As for going further north, it depends on the meteorological conditions in this place and whether there are conditions for economic planting.

2. Moisture: Mango is tolerant, but not waterlogged. Generally, it can be planted in places with annual rainfall above 700 cm. Sufficient water will make the nutritional growth of mango too strong, which is not conducive to flowering and fruiting, and will also aggravate the breeding and harm of pests and diseases. However, if the soil is too dry, it will cause flowers and fruits to fall. Long-term drought and showers during fruit development can also lead to mango fruit cracking. Moderate drought in the critical period of flower bud differentiation is beneficial to stop the growth of branches and make flower bud differentiation. The environment with sunny weather, relatively little rainfall and irrigation conditions at flowering stage is an ideal planting area for mango.

3. Illumination: Mango likes warm sunshine, and sufficient sunshine is very beneficial to the growth of mango. The flowering period is characterized by strong sunshine, warm weather and low relative temperature, which is beneficial to pollination and fertilization, high fruit setting rate, bright fruit color, rich flavor and storage resistance. Northbound orchards are prone to diseases and insect pests because of their low yield and weak light.

Fourth, the soil:

Mango has no strict requirements on soil quality. It can be planted in all types of soil, from alluvial soil to latosol, except for its extremely low salinity. Because mango is a deep-rooted fruit tree, it is required to be planted on a plot with deep soil layer, good drainage and low groundwater level. Because it is a mycorrhizal plant, the soil is required to be rich in organic matter and breathable, and the suitable pH value is 5.5-7.0. If the soil pH value exceeds 7.5 or is lower than 5, it will affect the growth and development of plants.
