以桉树人工林间种相思为研究对象,对比分析了间种不同相思并在施肥和不施肥情况下对林分生长及效益的影响,结果表明:相思的间种一定程度上提高了桉树的高生长2.6%~4.9%,极其显著地促进了桉树的胸径生长1.6%~6.8%,桉树单株材积同时获得显著增加5.88%~20.17%;6年生林分最终以桉树间种马占相思并在施肥的情况下获得最大价值,达到8 455元/667m2,而桉树纯林的价值为6 503元/667m2,相比提高了30.02%,经济效益极为显著。
Taking Acacia confusa as the research object, the effects of different Acacia species on the stand growth and benefit under fertilization and no fertilization were comparatively analyzed. The results showed that Acacia intercrops increased the height of Eucalyptus to a certain extent Growth of 2.6% to 4.9%, extremely significantly promoted the DBH growth of eucalyptus 1.6% to 6.8%, eucalyptus single plant volume at the same time significantly increased from 5.88% to 20.17%; 6-year-old stand finally eucalyptus stalks acacia and at Fertilizers obtained the maximum value, reaching 8 455 yuan / 667m2, while the value of pure eucalyptus forest 6 503 yuan / 667m2, an increase of 30.02%, the economic benefits are extremely significant.
