摘　　要：针对基质的斥水性问题,文章结合国内外研究近况,研究了润湿剂十二烷基苯磺酸钠和椰糠对基质吸水性能和持水能力的影响,并通过育苗试验检验了十二烷基苯磺酸钠和椰糠有无副作用。结果表明:润湿剂十二烷基苯磺酸钠和椰糠均能很好地增强基质的吸水性能和持水能力,且十二烷基苯磺酸钠和椰糠联合应用并未引起副作用。The experiment was conducted to study effects of sodium Sodium dodecylbenzensulfonate; Coconut coir on the water absorption and water retention characteristics of substrate, and the experiment of seedling was conducted to study if sodium dodecylbenzenesulfonate and coconut coir are harmful. The results showed that both sodium dodecylbenzenesulfonate and coconut coir can improve the water absorption and water retention characteristics of substrate, and that applying them together was not harmful, on the contrary, can promote seeds germinating
