Cultivated in the world for 40 S ~ 40 N, the suitable temperature for the whole year is 20 ~ 25°c, and the cold resistance varies with varieties (Mexican strain is stronger than Guatemalan strain, and West Indian strain is weaker). Cold-resistant varieties can tolerate the low temperature of -6℃, and varieties with low cold resistance will dry up when they encounter the low temperature of 0℃. The required annual rainfall is more than 1000mm, and the roots are shallow and the branches are fragile, which can not stand the strong wind, which can lead to yield reduction and strong adaptability to soil.

3. Avocados are also rich in potassium, folic acid and vitamin B6, and also contain a variety of mineral elements (potassium, calcium, iron, magnesium, phosphorus, sodium, zinc, copper, manganese, selenium and so on. ) and edible plant fiber.
