可降解编织物在土壤侵蚀控制和农业生产上的应用

Application of Degradable Geotextiles for Soil Erosion Control and Agriculture Production

在云南可降解编织物的原料来源广泛,取材也比较容易。水稻、小麦秸秆,棕榈,棕榈叶,竹子及麻类等均可作为可降解编织物的原料。可降解编织物覆盖在坡耕地表面,可防止雨滴溅蚀发生,减轻土壤侵蚀;可降解编织物覆盖能阻止土壤水分快速蒸发,保持土壤湿度,给作物供应充足的水分,从而促进作物生长,提高产量。本文综合分析了可降解编织物的原料来源、类型、在改善土壤理化性状和土壤结构中的作用、在水土保持和农业生产上的应用价值,分析了可降解编织物的社会经济效益,并讨论了可降解编织物的应用前景。

Sources for producing degradable geotextiles are easily available in Yunnan province, China. Rice and wheat stalks, palm leaves, bamboo and jutes are reasonable materials for degradable geotextiles production. Applying degradable geotextiles on surface of arable upland soil could effectively prevent soil from raindrop splash erosion, decrease soil erosion. It also could prevent soil water loss from fast transpiration, keep soil moisture and supply sufficient water for crop growth. In this paper, the sources for producing degradable geotextiles, type, function of improved in soil chemical properties and soil structure, and application of degradable geotextiles on agriculture and soil erosion were thoroughly discussed. The economic benefit and possibility of application of degradable geotextiles was discussed and reviewed.
