摘要
采用马尾松木荷台湾相思按2∶7∶1和4∶5∶1混交及马尾松火力楠杉木按1∶5∶4和5∶4∶1造林,19年生时研究其水文特征和土壤肥力状况。结果表明,马尾松木荷相思混交林持水能力高于马尾松火力楠杉木混交林,其中按2∶7∶1配比的马尾松木荷相思混交林其持水量最大,比按1∶5∶4配比的马尾松火力楠杉木混交林大19.43%,比按5∶4∶1配比的马尾松火力楠杉木混交林大24.43%。马尾松木荷相思混交林土壤肥力状况优于马尾松火力楠杉木混交林。马尾松木荷相思混交林具有更强的持水固土改土能力。
The mixed forests of Pinus massoniana with other tree species were planted,the mixed proportion was 2 P.massoniana,7 Schima superba and 1 Acacia confusa,as well as 4 P.massoniana,5 S.superba and 1 A.confusa,and 1 P.massoniana,5 Michelia macclurei and 4 Cunninghamia lanceolata,and also 5 P.massoniana,4 M.macclurei and 1 C.lanceolata.The hydrology and soil characteristics fertility status were studied when they were 19 years old.The results showed that water-holding capacity of the mixed forests of P.massoniana,S.superba and A.confusa was higher than that of P.massoniana,M.macclurei and C.lanceolata,of which the mixed proportion of 2 P.massoniana,7 S.superba and 1 A.confusa have the largest water holding capacity,larger than 1 P.massoniana,5 M.macclurei and 4 C.lanceolata for 19.43%,and 5 P.massoniana,4 M.macclurei and 1 C.lanceolata for 24.43%.The soil fertility of mixed forests of P.massoniana,S.superba and A.confusa were better than mixed forests of P.massoniana,M.macclurei and C.lanceolata.The mixed forests of P.massoniana,S.superba and A.confusa have strong capacity of soil water-holding and soil-transferring.
