Geographical distribution: generally grown in coastal saline-alkali land. Originally produced in Zhejiang Zhoushan Islands and coastal islands of Fujian, there are also distributions in Kouben and North Korea.
Ecological habits: Strong adaptability to soil and growth on acidic to alkaline soils. Hi light, heat resistant, cold resistant. The root system is developed, resistant to wind, moisture and drought. Resistant to trimming and easy to shape.
Breeding and cultivation: sowing or cutting propagation. Seeds can be harvested in late November, and seedlings can be dried or layered in the first half of March of the next year. In winter, anti-freezing measures should be taken for seedlings.
