| 摘 要： | 收集山核桃壳、锯末、枯枝落叶、菇渣、中药渣5种常见农林废弃材料,经过发酵和消毒处理,按照不同配比混合成8组不同的轻型栽培基质,测定其理化性质,并与日常栽培容器苗的轻型基质泥炭和珍珠岩比较。结果表明:8组不同轻型基质的容重、总孔隙度、通气孔隙、pH值、全N差异显著;持水孔隙、大小空隙比、EC值、全P、全K(除6、7号基质外)、速效K差异极显著(1%水平);以2号混合基质锯末:枯枝落叶:山核桃壳:珍珠岩=4:2:3:1(体积比)为最佳配比。

| Abstract: | Shell of Carya cathayensis,sawdust,litter,mushroom residues and herb residues were collected and mixed to 8 different light substrates with different ratio after fermentation and disinfection.Physical and chemical properties of them were determined and compared with those of common light substrates(peat and pearlite) for container seedlings.Results showed that bulk density,total porosity,non-capillary porosity,pH and total N of 8 light substrates had significant difference with that of the control.Water-hol... |
