早竹高产笋用林及其土壤理化性质分析研究

STUDY ON HIGH-YIELD PHYLLOSTACHYS PRAECOX FOREST FOR SHOOT AND ITS PHYSICAL AND CHEMICAL PROPERTIES OF SOIL

对临安县一专业户的小面积早竹高产笋用竹林及其土壤进行分析研究表明,早竹高产笋甩竹林需要有一个立竹度为13000株/hm^2,留枝盘数为10、叶面积系数10、3a内新竹数应占80％以上,无4a以上老竹的竹林结构;具有疏松的、透气透水性良好的土壤,对土壤养分元素特别是N素一般每公顷需750kg,N、P、K三要素控制在9:2:4;同时还须通过施肥、覆盖竹叶等一系列集约管理措施。

Study on small area high-yield Phyllostachys praecox forest for shoot and its soil showed that it was necessary for high-yield bamboo forest to have a density of 13000 culm/ha, 10 branches kept, leaf area index of 10, over 80% of new bamboo (≤3 years), no old bamboo (≥4 years); loosen soil with good air and water permeability, 750 kg/ha of N applicated, ratio of N. P. K. of 9:2:4; meanwhile, it was necessary also to applicate fertilizer, cover with bamboo leaves, etc..
