摘要
2011年1～5月持续干旱,使湖州竹产区的新竹胸径和成竹率下降,经济损失巨大。调查表明:干旱是造成新竹死亡的主要原因,而不同坡位、坡度、立地条件和经营措施,其竹林的危害程度不同。一般规律是上坡比下坡严重,陡坡比缓坡严重,山岗比山岙严重,土层深厚的黄泥土比砂性土严重。采用竹蔸施肥或仅打通竹蔸,其新竹成竹率均较高,达85%以上,说明采用此种方式,可起到缓解干旱的作用。
Constant drought from January to May,2011,is the reason for the reduction of the DBH and mature rate of new bamboo in Huzhou City,and leads to huge economic loss.The investigation showed that drought was the main reason for the death of new bamboo,but with different damages at different slopes,site conditions and management measures.The general rule was the damage was more severe at upper slope than at downhill,at steep slope than at flatter slope,and in deep yellow mud than in sandy soil.The mature rate of new bamboo was relatively higher,up 85%,if bamboo dump fertilization was applied,which indicated that this method can mitigate draught.
