First, about the soil.

1, soil depth

Zanthoxylum bungeanum is a shallow-rooted tree species, and its roots are mainly distributed in the soil layer 60 cm above the ground. Generally, the soil thickness is about 80 cm, which can basically meet the growth results of pepper.

2. Coarse density of soil

The previous answer is what is soil texture and its classification. Zanthoxylum bungeanum root system likes fertilizer and oxygen. Therefore, sandy loam and medium loam are most suitable for the growth and development of Zanthoxylum bungeanum, while sandy soil and extremely sticky soil are not conducive to the growth of Zanthoxylum bungeanum. Fertile soil can meet the requirements of vigorous growth and high yield of pepper. Of course, pepper is very adaptable to soil. Except extremely sticky soil and coarse sandy land, marshland and saline-alkali land, general sandy soil, light loam and light loam can be planted.

3. Soil pH value

Zanthoxylum bungeanum can be planted in the range of soil pH 6.5-8.0, but it grows best in the range of pH 7. 0-7.5.

Second, about altitude.

Zanthoxylum bungeanum is basically not limited by altitude. What we can see is planted at 2500M in Qinghai, 500M above sea level in Sichuan Basin is still the main producing area, and it is also planted at tens of meters in Shandong, so you can see the place, and the altitude can basically meet the planting requirements.
