Banana living environment characteristics

Living environment:

The banana root group is delicate, the choice of soil is more stringent, poor aeration, poor structure of the clay soil or poor drainage, are very unfavorable to the development of the root system, to clay content <40%, the water table in the sandy loam below 1 meter, especially alluvial loam or humus loam is suitable. Rainfall to a monthly average of 100 millimeters is the most appropriate, less than 50 millimeters is a dry season, banana due to lack of water and the prolongation of buds, fruit refers to short, low yields. If the banana garden is waterlogged or flooded, light leaf yellowing, easy to induce leaf spot eclampsia, yield drop, heavy root group suffocation rot to plant death. Banana distribution area of large multi-year average of more than 21 ℃, a few 20 ℃ or so, bananas require high temperature and humidity, the growth temperature of 20 ~ 35 ℃, the most suitable for 24 ~ 32 ℃, the lowest should not be lower than 15.5 ℃. Banana is afraid of low temperature, avoid frost and snow, cold hardiness than plantain, plantain weak. Growth inhibited by the critical temperature of 10 ℃, down to 5 ℃ when the leaves are yellowed by cold, 1 ~ 2 ℃ leaves withered. Fruit at 12 ℃ that is cold damage, ripening consequences of the skin grayish yellow, affecting the commercial value.
