摘　　要：[目的]筛选适宜于潮汐式育苗的基质类型。[方法]采用潮汐式育苗的方式,以辣椒为试验材料,通过对各基质的理化指标和辣椒苗期的生长、生理指标检测,对4种不同类型基质进行了比较试验。[结果]以椰糠为主原料的基质育苗,辣椒出苗后3 d基本齐苗,出苗率达91.6%;3个不同时期辣椒幼苗的株高和茎粗也均好于其他类型基质;辣椒幼苗的叶绿素含量、根系活力、植株的干(鲜)重和壮苗指数的测定值均是最好的。[结论]以椰糠为主原料的基质在辣椒潮汐式育苗的应用中表现较好,其理化指标均在合适的范围之内。[Objective] Pepper seedling substrates with ebb and flow bench system were screened. [Method] Pepper seedlings were planted in four kinds of substrates by using ebb and flow bench system. The physical and chemical characteristics of substrates and the growth and physiological indexes of pepper seedlings were tested. [Result]The emergence rate of pepper with in coir dust was 91. 6% after 3 days of emergence. The plant height and stem diameter were all better than other substrates in three different periods. The chlorophyll content,root activity,fresh and dry weight,seedling strength index of pepper seedling were all the best. [Conclusion]The results showed that the coir dust was better than other three substrates,which were all in reasonable range.
