| Abstract: | The research on biological amelioration ways to the lands of eucalyptus(E. calophylla or E. citriodara) plantations in Leizhou Peninsula was carried out between 1990 and 1992. Results showed that, the interplantings of green manure crops,forage grasses, or pineapple (Ananas comosus) under eucalyptus plantations could in.crease vegetation coverage and litter mass of the forest lands,enhance soil fertility,promote the growth of eucalyptus. In the research, a plant variety that was more suitablefor interplanting under eucalyptus plantation was selected,and the economic benefit ofthe interplantings was analysed. |
