Among them, caribbean pine, evening pine, bankers, just loose, silver Jing, Acacia mangium, Mexican cypress, cypress and other eight species of trees are more prominent. Through many years’ hard observation and research by forestry workers, the biological characteristics (growth process, flowering and fruiting, adaptability) of 8 tree species have been initially mastered, and the suitable range of each tree species has been put forward. 1. Caribbean pine suitable for planting in our tropical and southern subtropical hilly and coastal sandy land, is an excellent timber
