Study on the main Physico-chemical Properties of Coir Culture Medium in Hainan
摘要
Abstract
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.关键词
