There is a small amount of Pennisetum pinnatifida distributed at the altitude of 1000 meters in the Qinling remnant vein in western Henan, China, which likes light and grows well on the semi-sunny slope or sunny slope. I like loose and fertile soil, but the root system has strong resilience and can grow tenaciously in barren and dry stone piles in mountainous areas. Castanopsis fissa is drought-resistant, rain-proof, hail-proof, high temperature-resistant and barren-resistant, and no obvious pests and diseases are found.
