Extended data:
Ginkgo biloba is a light-loving tree with deep roots and wide adaptability to climate and soil. It can grow in areas with high temperature, rainy, little rainfall and cold winter, but it grows slowly or badly.
It can grow on acidic soil (pH 4.5), calcareous soil (pH 8) and neutral soil, but it is not tolerant to saline-alkali and over-wet soil.
Born below the altitude of 1000 (Yunnan 1500-2000) meters, the climate is warm and humid, the annual precipitation is 700- 1500 mm, the soil layer is deep, fertile and humid, the areas with good drainage grow best, the soil is barren and dry, and the places with excessively wet rock slopes will not survive or grow badly.
