棕榈纤维垫法恢复水库岸边植被施工技术

Technique of Macrophyte Restoration in Littoral Zone by Palm Mat with Interpolatory Sallow

利用经特殊工艺编制而成的棕榈纤维垫,扦插柳枝、芦苇和种植各种生活习性植物的方法,恢复洋河水库岸边植物带的施工技术。利用棕榈纤维垫保持十壤、涵养水分的功能.在洋河水库岸边裸露的沙砾、岩石基底上.铺盖棕榈纤维垫,覆盖约5 cm厚的土壤,扦插柳枝、芦苇并种植各种生活习性的植物,成功地恢复了库边植物。扦插的柳枝成活率97%以上,扦插芦苇的成活率约40%,其它植物的成活率都大于75%以上,特别是移栽当地的稻李氏禾(线草), 挺水、陆地均成活率高、长势好,快速起到防雨水冲刷斜面、保土的作用。

The method using specially processed palm mat with interpolatory sallow for restoration of macrophyte in Yanghe littoral zone was introduce＆ The palm mat possesses functions of holding soil and preserving water. The palm mat was spread over surface of Yanghe littoral zone and 5 cm thick soil covered the palm mat. Some herbaceous plantsg rew while finishing interpolatory sallow. The restoration macrophyte for Yanghe littoral zone was successful with more than 95% survival rate of interpolatory sallow, 40% survival rate of the reed and 75% of that of other plants. Especially, the Leersia Sw had high survival rate whether it grew in water or stood on terrene. It soon brought into play protection of soil from erosion in the edge of the littoral zone.
