毛竹低产林改造及效果分析

Analysis on Effect of Low——Yield Forest of Phyllostachys pubescens Mazel

摘要:

对延平区巨口乡员垱洲半山自然村的毛竹低产林进行改造试验,结果表明:毛竹低产林实施带状垦复、施肥等改造措施,林分各项生长指标均得到提高,与对照毛竹林比较,改造林分高、胸径和竹产量3项指标均达0.01水平显著差异,其增益分别为49.5%,55.0%,192.8%。通过改造,能够改善毛竹的生长环境,提高发笋率,促进竹笋萌发成长为新竹,同时可以提高毛竹质量和产量。

Abstract:

The Improvement test on low-yield forest of Phyllostachys pubescens Mazel was carried out from Banshan natural village of Yuandangzhou village,Jukou township in Yanping district.Results indicated that various growth index like standing forest,etc,was enhanced by the transformation of reclamation with strips and reasonable fertilization etc.Comparing with referent forest of Phyllostachys pubescens Mazel,three indices,such as standing-forest-height,D.B.H.and bamboo yield all achieved the level 0.01,and had marked differences.The gain was 49.5%,55.0%,192.8% respectively.Via improvement,the condition of bamboo growth and the productivity of bamboo shoot were improved,the bamboo shoot was advanced to burgeon and grows to be fresh bamboo,and meanwhile,the quality and yield were also improved.
