摘要
无纺布具有保温、保湿、透气等特点,被广泛应用于农业、环境和绿化等领域,其正加速取代传统塑料农膜,成为地膜领域使用占比最高的材料.主要阐述了无纺布在农作物、生态修复和园林绿化3个方面的应用.无纺布覆盖可以提高植物种子萌发率、产量与质量.盐碱地覆盖无纺布可有效阻隔土壤盐分运移,通过抑制水分蒸发而降低土壤表层盐浓度.无纺布育苗容器能有效控制根系缠绕并可作为垂直绿化载体.无纺布覆盖与应用虽越来越广泛,但其在使用过程中也面临着回收利用不充分和过度消耗土壤肥力的问题,因此,从机理研究、回收利用、改良和专用4个方面提出了合理化建议.
Abstract
Nonwoven fabrics,characterized by their heat preservation,moisture retention,and air permeability,are extensively utilized in agriculture,environmental protection,and greening initiatives.They are rapidly replacing traditional plastic agricultural film and have become the widely used materials in the field of plastic film.The application of non-woven fabrics in crop cultivation,ecological restoration,and landscape greening was expounded in the present study.Non-woven fabric coverage can improve the germination rate of plant seeds,crop yield and quality.Covering saline alkali land with non-woven fabrics can effectively block the movement of salt and reduce the salt concentration on soil surface by inhibiting water evaporation.Containers made of non-woven fabrics can effectively control the root entanglement and can be served as vertical greening carriers.Although the application of nonwoven fabric covers is becoming increasingly widespread,it also faces issues such as inadequate recycling and excessive consumption of soil fertility.Therefore,rational suggestions are proposed from four aspects:mechanism research,recycling utilization,improvement,and specialization of non-woven fabric.
