摘要
对早园竹林实施覆盖技术后，其负面作用也逐渐显露出来，主要表现在：产量呈下降趋势，新留母竹出现高位枯死（猝死）和生育不正常等。另外，值得深思的是，在高度集约经营条件下，原有的竹龄结构模式是否还适应等。为此，提出必须从基础抓起，提高科学管理水平，调整竹林结构，及时留养母竹，建立二层竹冠，改善竹林生态条件等对策。
The coverage in Phyllostachys propinqua stand had negative effect: the output decreased gradually、the last left mother bamboo dead at the high point and irregular growed. Meanwhile, points for attention that whether the age structure is reasonable under intensive cultivation. Therefore,the countermeasures such as improving management,adju-sting the age structure,keeping mother bamboo,establishing two layer crown, improving the ecological environment in the stand are suggested.
