摘要
[目的]比较不同竹种林下土壤的营养元素含量.[方法]在福建农林大学百竹园内选取大明竹、牡竹、角竹、花巨竹和大木竹5个竹种,分别于春、夏、秋、冬4个季节对其林下土壤进行“S”型多点采样,对其氮、磷、钾含量进行测定.[结果]大明竹、牡竹、角竹、花巨竹和大木竹5个竹种林下土壤的营养元素含量皆较高,但各竹种之间的营养元素含量有显著差异,且各竹种在不同季节的营养元素含量也有明显差异.其中大明竹林下土壤的营养元素含量最高,且最为稳定,牡竹相对较差.[结论]在福建地区,大明竹对营养元素的产生及维系稳定具有良好的能力,可成为该地区城市观赏用竹及发展林下经济的优良竹种.
Abstract
[Objective] Nutrient element content in soil of 5 bamboo species was compared.[Method] We selected 5 bamboo species Pleioblastus gramineus (Bean) Nakai,Dendrocalamus strictus (Roxb.) Nees,Phyllostachys fimbriligula Wen,Gigantochloa verticillata and Lingnania wenchouensis Wen in Bai ju Chuk Yuen of Fujian Agriculture and Forestry University.Respectively,S-type multi-sampling was conducted under its forest soil in the spring,summer,autumn and winter.The content of nitrogen,phosphorus and potassium were determined.[Result] The results showed that nutrient element content of 5 bamboo species was high,but there were still significant differences among the 5 species,and the nutrient element content of each bamboo species in different seasons had significant differences.P.gramineus(Bean) Nakai showed the highest nutrient element content,and it was the most stable of all.D.strictus (Roxb.) Nees was relatively poor.[Conclusion] This indicates that the genus of P.gramineus(Bean) Nakai could produce nitrogen nutrients and maintain stable with good ability,which can be used as urban ornamental bamboo and fine bamboo that promoting economic development.
