temperature
Mango likes warmth, not cold and frost. The optimum growth temperature is 25-30℃. When the temperature is lower than 20℃, the growth is slow. When the temperature is lower than 10℃, the leaves and inflorescences will stop growing, and the nearly ripe fruits will suffer from chilling injury. The annual average temperature in mango producing areas in the world is above 20℃, and the monthly minimum temperature is above 15℃. The average annual temperature in the producing areas with normal growth in China is 19.8-24. 1℃, but the average annual temperature is 2 1-22℃, and the highest temperature in Leng Yue exceeds 15℃, and there are many areas with almost no frost all the year round. The effective temperature for mango growth is 18-35℃, the suitable temperature for new shoot growth is 24-29℃, and the average daily temperature for fruit setting and young fruit growth should be greater than 20℃.
illuminate
Mango is a kind of fruit tree that likes light. Adequate light can promote flower bud differentiation, blossom and set fruit, improve fruit quality and appearance. Usually, there are many flowers per plant with sunny crown or open environment, and the fruit setting rate is high; Mango with too many branches and leaves, closed crown and insufficient light has less flowers and fruits, and its fruit appearance and quality are poor. Through shaping and pruning, the lighting conditions in the garden and trees can be improved, the yield can be increased and the high-yield period can be prolonged.
moisture
Mango grows well in the area with annual rainfall of 700-2000 mm, but the uneven distribution of annual rainfall in South China often affects its growth and development. If the air is too dry during flowering and early fruiting, it is easy to cause falling flowers and fruits; Too much rain leads to rotten flowers and poor pollination and fertilization; Too concentrated rainfall in summer often induces serious fruit diseases; Autumn drought after harvest mostly affects the germination and growth of autumn shoot mother branches.
geographical distribution
Yunnan, Guangxi, Guangdong, Fujian and Taiwan Province provinces were born in hillsides, river valleys or wild forests at an altitude of 200-1350m. India, Bengal, zhina Peninsula and Malaysia. This species is widely cultivated all over the world, and has bred more than 100 varieties, and more than 40 varieties have been bred in China.
