摘要
采用林间套种牧草、绿肥和灌木，对巫山马尾松残林进行改造。结果表明，马尾松套种牧草、绿肥和薪材林后，与对照相比，年均生长树高分别增加２．３３，１．８３，２．０倍，地径分别增加５．５３，６．４１，５．０倍，马尾松干生物量分别增加２．０４，２．３４，１．７倍，并改善了土壤理化性质，减少水土流失。
In an effort to rehabilitate the deteriorating masson pine ( Pinus massoniana ) stand in Wushan county, pasturage and green manure crops and fuelwood shrubs were intercropped in the pine forest. Compared with the non treated control, the average annual growth of pine trees in height of the three treatments mentioned above increased by 133, 83 and 100%; the average annual growth in diameter at the foot by 453, 541 and 400%; and dry biomass of the trees by 104, 134 and 70%, respectively. The rehabilitation measures also improved the physico chemical properties of the soil and reduced soil erosion.
