摘要
雷竹作为优良的笋用竹种,在长江以南各省被大面积栽培。浙江省德清县是雷竹笋重点产区之一,雷竹笋产业已成为该县林业主导产业,近几年雷竹笋亩产值虽呈上升趋势,但亩产量却逐年下降。针对以上问题,我们在德清县雷竹林重点乡镇采集了56个土壤样品进行测定,结果表明:德清县雷竹林地土壤酸化严重,土壤有机质、氮、磷和钾含量偏高。雷竹林高效栽培技术推广,虽然使农户收入增加,但同时也造成雷竹林退化,土壤酸化及氮、磷和钾的富集。该文在数据分析的基础上,对德清县雷竹林经营提出测土施肥和轮休的方法,改进雷竹林经营方式,实现雷竹林的可持续经营。
As an excellent shoots-oriented bamboo species,Phyllostachys violascens is widely planted in the south of the Yangtze River. Deqing County of Zhejiang Province is one of the most important areas of Ph. violascens cultivation. The Ph. violascens bamboo shoot industry has become a leading sector there. In recent years,the production value per acre has been increasing,but the yield per acre has been decreasing. Therefore,we collected and measured56 soil samples from Ph. violascens forests at various villages and towns of Deqing County. The results showed that the soil of Ph. violascens forests in Deqing County acidified severely.Moreover,the contents of soil organic matter,nitrogen,phosphorus as well as potassium were excessive. With the popularization of efficient cultivation technology of Ph. violascens,although the farmer's income has increased,it has led to the degradation of bamboo forest land,acidification of soil and enrichment of nitrogen,phosphorus and potassium. It is suggested that the methods of soil testing fertilization and fallow should be adopted to improve the bamboo forest management and achieve its sustainability.
