低产毛竹林改造技术的调查研究

对福建省低产毛竹林的改造技术进行调查，结果表明；不同类型的低产毛竹林应采取不同的改造技术措施，深翻改土是残败型毛竹林改造的关键措施；劈山清杂、加强垦复抚育管理和适当增施肥料是荒芜型低产毛竹林改造的重要措施，而调整竹林的年龄结构则是提高低产竹林产量和质量的根本途径。

An Investigation on the Techniques of Remaking the Low-Yield Forests of Phyllostachys pubescens

An investigation was conducted on the techniques of remaking the low-yield forests of Phyl-lostachys pubescens in Fujian Province and the results indicated that different technical remake measuresshould be adopted for different types of low-yield forests of Ph.pubescens:deep tillage for improving soilswas a key technical measure for remaking a residual and degenerative type of Ph.pubescens forests; choppinghills and clearing sundry brushes and grass,intensifying reclamation and tending management and adding fer-tilizers were important measures for remaking a waste type of low- yield forests of Ph.pubescens :and adjust- ing the age structure of bamboo forests was a root way to increase both yield and quality of low- yield bamboororests。
