Environmental requirements of coconut producing area
1, temperature
The requirement of temperature is the limiting factor that affects the distribution range and yield of coconut. Coconut can blossom and bear fruit normally in areas where the annual average temperature is 24-25℃, the temperature difference is small and there is no frost all year round.
The ideal annual average temperature is 26-27℃, the lowest monthly average temperature is not less than 20℃, and the temperature difference is not more than 5-7℃. Coconut grows luxuriantly, develops normally and has high yield. In tropical marginal areas, coconut can tolerate the occasional low temperature and the extreme low temperature reaches 0℃ in a short time, but the growth and development of fruit are affected to some extent.
2. Moisture
Annual rainfall1300-2300mm, evenly distributed, suitable for coconut production. The soil is well drained, and the rainfall is as high as 3800 mm. In areas where irrigation can be carried out, the annual rainfall of 600-800 mm can also adapt, which will affect coconut production in severe drought.
3. Humidity
It is generally believed that 80-90% humidity is suitable for coconut growth, and less than 60% affects the growth.

The History of Coconut in China
According to historical records, when Zhuge Liang went to Yunnan, he ordered his soldiers to cut down coconut trees, saying that "it is not necessary to make Xiaobang have some foreign objects, but to eat more and be angry". If so, it shows that Zhuge Liang has misunderstood coconut. However, it can be explained from one side that coconut cultivation existed in Yunnan during the Three Kingdoms period.
The Southern Vegetation, written by Ji Han in Jin Dynasty (AD 304), accurately described coconuts. Su Dongpo lived in Danzhou, Hainan Province, and called coconut water "a fine wine makes a forest", and wrote poems praising the "coconut crown" carved with coconut shells. Qiu Jun, a famous Hainan person, said that coconut is "suitable for one thing and ten uses" in "Ode to Qidian in Nane".
