Minnan refers to the southern part of Fujian. Geographically, Xiamen, Quanzhou, Zhangzhou, Putian and Longyan can all be called Minnan, belonging to the hilly areas of the south of the Yangtze River. Geographical conditions include landform, climate, geographical location and vegetation.
Terrain: The sandy soil in hilly area is alkaline.
Climate: subtropical monsoon humid climate, rain and heat are suitable for crop growth.
Vegetation: subtropical evergreen broad-leaved forest
Location: Low latitude, small solar altitude angle and abundant sunshine.
Growth habit of papaya
Plant in sunny, fertile, humid and well-drained places, or plant in fields, hillsides, in front of and behind houses. When planted in pieces, holes should be opened at the row spacing of1m * 2 m. Papaya has shallow roots and strong tillering ability, and many seedlings can grow from the roots every year. After 1-2 years of cultivation, it will be planted in the nursery; The big ones can be planted directly.
Growth environment of mango
1, Temperature: Mango prefers warmth to frost. 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 that can grow and bear fruit normally in China is 19. 8-24. 1℃, but the annual average temperature is 2 1-22℃, and the highest temperature in Leng Yue is above 15℃, and there are many frost-free areas almost all 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℃. Insufficient temperature, poor pollination and fertilization, and even inflorescence death or embryo abortion death. When the temperature is higher than 37℃, the fruit of Kobanawa will be sunburned; When the temperature is lower than 10℃, the growth of new shoots and spikes stops; When the temperature is lower than 5℃, seedlings, shoots and spikes will get cold. When the temperature is about 0℃, the aboveground parts of seedlings, the flowers and shoots of adult trees, and the peripheral leaves of 20 immature mangoes on the trees will all suffer, and even die in severe cases. Young trees below -3℃ freeze to death, and big trees freeze seriously.
2. Light: 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 fruit with too many branches and leaves, closed crown and insufficient light has few flowers and fruits, and its appearance and quality are poor. We can improve the lighting conditions in the garden and trees by shaping and pruning, thus increasing the yield and prolonging the high-yield period.
3. Moisture: Mango grows well in the area with annual rainfall of 700-2000mm, and 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.
