What does it mean that the bottom of Castanopsis fissa is covered with four-leaf clover?

The bottom of the chestnut is covered with four-leaf clover, indicating that the land is fertile. Pueraria lobata, alias Ficus caudata, Ficus finch and Ficus macrophylla. Pueraria lobata is a tall deciduous tree. The thick stems are strange, the roots are exposed, and the roots are intertwined, making the past serve the present. Dense branches, large branches extending horizontally, and branchlets obliquely bent. The leaves are dense and oily green. Life span is very long, and trees over 100 years old abound. The flowering period is May-August, and the fruiting period is August-165438+1October. The fruit is spherical, yellow or purple. Pueraria lobata likes light and takes root with breath. Born in the wetland near sparse forests or streams, it is a positive tree species, likes warm, high temperature and humid climate, is drought-tolerant but not cold-tolerant, and has a slightly stronger cold tolerance than banyan. It is resistant to wind, air pollution, barren, lax in quality requirements, rapid in growth, strong in germination and easy to plant. In spring (before and after the rain and solar terms), the yellow barrel tree will grow many tender buds, which are light green and petite.
