摘　　要：以海南3市(县)5镇的椰糠为材料,对不同地域椰糠的容重(BD)、总孔隙度(TP)、阳离子交换量(CEC)、大小孔隙比(RLSP)、持水空隙度(WFP)、通气空隙度(AP)、灰分含量(AC)、pH值及EC值等理化特性及其相关性进行研究。结果表明:椰糠BD和TP的范围分别为0.09～0.25 g/cm3和73.00%～86.00%,pH、EC值和CEC的范围分别在4.50～7.00、1.35～3.60 mS/cm、32.40～55.00 mol/hg之间,RLSP、AP、WFP和AC的范围分别在0.03%～0.13%、2.60%～8.20%、70.00%～82.00%、6.00%～51.00%之间。对不同地域的椰糠理化特性的相关性分析表明,BD分别与EC、pH、AC,TP与AP,RLSP与WFP,pH与EC,EC与AC,AC与pH呈极显著正相关;TP与BD,RLSP与AP,WFP与AP,AC与TP呈极显著负相关;BD与AP,CEC与EC、pH,RLSP与AC呈显著负相关。The coir samples named as WDJ1,WDJ2,WDJ3,WMD,WMX,WWF,WWD,SHC,SHY,LHM,LHJ were collected from different locations of Hainan as the experimental materials.The bulk density（BD）,total porosity（TP）,cation exchange content（CEC）,ratio of large pores and small pores（RLSP）,water-filled pores（WFP）,aerial pores（AP）,ash content（AC）,pH and electric conductivity value（EC）were studied.The results showed that BD and TP of coir were ranged from 0.09～0.25 g.cm-3 and 71.00%～86.00%,respectively.pH,EC value and CEC were ranged from 4.50 to 7.00,1.35 to 3.60 mS/cm and 32.40 to 55.00 mol/hg,respectively.RLSP,AP,WFP and AC were ranged from 0.03% to 0.13%,from 2.60% to 8.20%,from 73.50% to 81.70% and from 5.90% to 51.00%,respectively.The BD and EC,pH,AC,TP and AP,RLSP and WFP,pH and EC,EC and AC,AC and pH showed significant positive correlation;But TP and BD,RLSP and AP,WFP and AP,AC and TP showed significant negative correlation;The correlation between BD and AP,CEC and EC,pH,RLSP and AC also showed significant negative correlation.
