低产毛竹林改建笋用林高产技术的研究

Study on Technique for Transforming Low Yield Bamboo Forest into High Yield One for Shoot Producing

低产毛竹林改建笋用林成效显著。试验区每度平均亩产笋828.8公斤,经济收入935.02元,投入与产出之比为1:5.05。低产林能迅速改变成为每年出笋养竹的花年(均年)笋用林,竹笋产量与对照区同期比较,提高6.84倍。实践表明:集约经营,科学管理,适当施肥,年年留养是改变毛竹山笋大小年现象的捷径。

Annual output of bamboo shoot per mu reached 828. 8 kg in experimental area,equal to 935.02 yuan RMB. The ratio of imput to output was 1:5.05. Low yield stand couldbe quickly transformed into on-off yield one for shoot-producing. Output of shoot in thesample plot was 6. 84 times compared with the control It showed that intensive management,scientifical administration, rational fertilization and keeping mother bamboo every year werethe best way for transforming on and off year in bamboo stand.
