The growing environment of coconut trees
Coconut is a tropical light-loving crop, which grows well in high temperature, rainy, sunny and sea breeze. It is required that the annual average temperature is above 24-25 degrees, the temperature difference is small, and there is no frost all year round, so that coconuts can blossom and bear fruit normally, and the optimum growth temperature is 26-27 degrees.
It is suitable for growing in low altitude areas, and Hainan Island in China can grow well below 150-200m. It is required that the annual average temperature is above 24-25℃, the temperature difference is small, and there is no frost all year round, so that coconuts can blossom and bear fruit normally, and the optimum growth temperature is 26-27℃. If the average temperature of a month in a year is 18℃, its output will drop obviously. If the average temperature is lower than 15℃,
Will lead to falling flowers, fruit and leaves turning yellow. The moisture condition should be that the annual rainfall is greater than 1500-2000mm, and it is evenly distributed. However, in areas with abundant underground water sources or irrigation, it can grow well when the annual rainfall is 600-800 mm. Drought affects coconut yield for 2-3 years, and long-term water accumulation will also affect coconut growth and yield.
As far as soil fertility is concerned, it is required to be rich in potassium fertilizer. Soil pH can be 5.2-8.3, but 7.0 is the most suitable. Coconut has strong wind resistance, and strong winds of 6-7 have only a slight impact on its growth and yield. A typhoon of magnitude 8-9 can blow off several leaves and tear up leaflets. Strong typhoons above 10- 12 do serious harm to coconuts. The conditions are suitable, and the coconut will begin to bear fruit after two years of planting.
