First, the temperature: Mango hi-high temperature, not cold, flowering period is more sensitive to the rain of cold weather. The effective temperature for the growth of mangoes is 15-35°C, and the optimum temperature for growth is 24-27°C. Flowering above 20 °C can normal pollination and fertilization. Below 20 °C, the anther does not crack, pollen does not germinate, affecting the results. The saplings can be killed at -3°C, and large trees can also be seriously frostbite. Therefore, the local temperature is the limit of the mango planting. According to statistics, the northern limit of mango introduction in China is 2743′ north latitude, but generally speaking, China's Tropic of Cancer is the northern margin of mango economic cultivation. As for further northward movement, it depends on the meteorological conditions in the local area to determine whether there is Economic cultivation conditions. Second, water: Mango is more resistant, but not tolerant, the general annual rainfall of more than 700 cm can be planted. Adequate moisture will make Mango's nutrients grow too profusely, which is not conducive to flowering results. At the same time, it will increase the breeding and harm of diseases and insect pests. However, if the soil is too arid, it will cause flowering and fruit drop. A long, rainy shower during fruit development can also cause mango cracking. Moderate drought during the critical period of flower bud differentiation is conducive to stop shoot growth and flower bud differentiation. Clear weather during the flowering period, relatively little rainfall, and an irrigated environment are the ideal areas for growing mangoes. Third, light: Mango is a good light, abundant sunlight is very beneficial to the growth and fruiting of mango, strong sunshine during flowering, warm weather, relatively low temperature, is conducive to pollination and fertilization, high seed setting rate, bright fruit color, rich flavor , Storage-resistant. The orchard in the north-orientation direction has low output and is prone to pests and diseases due to weak light. Fourth, soil: Mango on the soil texture requirements are not very strict, in addition to extremely poor salinity, from alluvial soil to brick red soil and other types of soil can be planted. Since mangoes are deep-rooted fruit trees, they are required to be planted on plots with deep soil, good drainage and low groundwater levels. Because it is a kind of mycorrhizal plant, it is required that the soil is rich in organic matter, and its permeability is strong. The pH value of 55-70 is more suitable. If the pH of the soil exceeds 75 or less than 5, the growth and development of the plant will be affected.
