摘要： 为开发松针资源作为高附加值植生袋基质材料的新途径，以松针为材料，对松针和椰糠的理化性状进行测定和分析比较。结果表明：松针的总孔隙度为88.64%，持水能力为293%，pH 6.12，电导率为1.10 mS/cm，都处于无土栽培的适用范围；松针阳离子交换量(59.8 cmol/kg)略小于椰糠(67.1 cmol/kg)；与椰糠相比，松针的矿质元素含量更为丰富，能够一定程度上为植物提供养分；松针的酸、碱、盐缓冲容量分别为0.0689、0.1033、0.1202 mol/kg，椰糠为0.0567、0.0842、0.1394 mol/kg，两者相差不大。松针可以作为有机栽培基质。研究既对无土栽培和植生袋的推广应用提供一定的参考，又为可再生林下资源松针的利用提供了新途径。

Abstract: In order to explore pine needles as a high value-added material for grow bags, the physicochemical properties of pine needles and coconut coir were determined and analyzed. The results showed that the total porosity of pine needles was 88.64%, water holding capacity was 293%, pH value was 6.12, the electrical conductivity was 1.10 mS/cm, indicating that both factors were within excellent soilless cultivation substrate scope. Electronic conductivity value of pine needles was 59.8 cmol/kg, slightly less than that of coconut coir (67.1 cmol/kg). Content of mineral elements of pine needles were richer than that of coconut coir, it could provide nutrients for the plants to a certain extent. The acid, alkaline and saline buffering capacity of pine needles were 0.0689, 0.1033 and 0.1202 mol/kg, respectively, and those of the coconut coir were 0.0567, 0.0842 and 0.1394 mol/kg, respectively, they had similar buffering capacity. This study provided not only a reference for soilless cultivation and planting application of grow bags, but also a new way for using pine needle as renewable forest resource.
