It is distributed wild in Yunnan. It likes sun, tolerates drought, avoids shade and stagnant water. It is mostly distributed in areas with less rainfall. It can tolerate light frost and can be planted in tropical and south subtropical areas. The general propagation method is seed propagation, and the seedling transplanting method is often used. Live broadcast can also be used.
The growth environment of Sappan wood:
In Guangxi, China, it is mostly distributed in the karst low mountains and hills of southwest Guangxi. Vertical distribution is generally below 500 meters above sea level. Sappan requires a warm and humid climate.
In the distribution area, the annual average temperature is 22℃, the average temperature of the hottest month is 27-29℃, the average temperature of the coldest month is 12-14℃, the absolute minimum temperature is -2.2℃, and the effective accumulated temperature is 7400-7900℃ . The annual rainfall is 1000-2000 mm, and the relative humidity is about 80%. The frost-free period can last for more than eleven and a half months, and it can withstand short-term low temperatures of around 0°C.
Sugar can grow in brown and black lime soil, brick red soil and brick red soil. However, it grows well in black lime soil with deep, fertile and moist soil, neutral to slightly alkaline (pH 6.8-7.6), and can also grow on lean and dry mountain tops and ridges.
Sappan wood can tolerate shade and can grow in valley jungles, especially in the seedling stage. According to seedling breeding experiments conducted by the Guangxi Institute of Forestry, seedlings with shade increased by more than 25% on average compared to those without shade.
