Coconut trees are widely distributed in tropical coastal and inland areas of Asia, Africa, Oceania and America. It is mainly distributed between 20 degrees north and south latitude, especially in equatorial coastal areas, followed by a large area within 20-23.5 degrees north and south latitude.
Coconuts in China are mainly distributed in the whole Hainan Island, accounting for about 80% of the total area and output of the country. In addition, Xisha and Nansha Islands, Shangchuan and Xia Chuan Islands in Guangdong, Tainan and Xishuangbanna in Yunnan, Beihai and Qinzhou in Guangxi are also planted in small quantities.
Its branches and leaves are particularly lush. The leaves are like a big broom and a mulberry tree. There are coconut stalks supporting sword-like leaves on the tall trunk. The petiole is very hard, and it takes a lot of strength to break it. The flowers of coconut trees are white and small, so you should pay attention to observation to find them.
What are the requirements for the growing environment of coconuts?
1, temperature: Temperature requirement is the limiting factor affecting the distribution and yield of coconut. The average annual temperature is 24-25℃, and the temperature difference is small, so coconuts can blossom and bear fruit normally in the frost-free period all year round. The optimum annual average temperature is 26ー27℃, the monthly average minimum temperature is not lower than 20℃, and the temperature difference is not more than 5 7℃. Coconut grows vigorously, develops normally and has high yield. In tropical marginal areas, there is occasional low temperature, and the extreme low temperature is as high as 0℃ for a short time. Coconuts can tolerate it, but the growth and development of fruits are affected.
2. Water: the annual rainfall is 1300-2300mm, which is evenly distributed and suitable for coconut production.
3. Illumination: Coconut is a strong light crop, which needs 2000 hours of illumination every year, with an average of 120 hours per month. Coconut growth below this level will be affected.
4. Altitude: Generally speaking, coconuts are suitable for planting in low latitudes and high altitudes. Coconuts are generally distributed in coastal low-altitude areas, and are most suitable for planting in areas with an altitude of 100-200 meters.
