在１９９１年冬被皆伐的残次阔叶林中，１９９３年进行抚育间伐、补植造林、封山等措施试验表明，抚育间伐试验林生长快，１９９４年平均树高３．２ｍ．改造后１９９３～１９９４年两年树高生长量１．８ｍ，与集约经营的１９９２年新造菇木林相近，菇本产量高，１９９４年出重２００００ｋｇ／ｈｍ２，超过封山林和新造林。封山林生长良好，总生物量大，林本生长量和菇木产量次之。枫香适应性强，生长较快，是菇木林建设的先锋树种。抚育间伐、补植、封山等措施费用省、效果好，对我区提高现有阔叶林资源的菇木林生产力，具有较好的推广应用价值。
In the remnant broadleaved forest where the winters were clear-cut in 1991, tests such as tending and thinning, plantation and mountain closure in 1993 showed that tending thinning test forests grew rapidly with an average tree height of 3.2m in 1994. After transformation, the height growth of trees in the two years from 1993 to 1994 was 1.8m, which was similar to intensive management of new mushroom forest in 1992. The output of mushroom was high, and the output was 20000kg / hm2 in 1994, exceeding the closing forest and newly afforestation. Sealing forest growth well, the total biomass, forest growth and mushroom yield second. Liquidambar adaptability, rapid growth, is the pioneer mushroom tree species. Tending the thinning, replanting, sealing and other measures cost provinces, the effect is good, to enhance my existing forest broad-leaved forests mushroom productivity, has a good promotion and application value.
