摘　　要：通过室内盆栽试验,研究了木屑、松针、核鳞、树皮及枯叶5种有机覆盖物覆盖土壤表面对城市园林植物土壤含水量的影响。结果表明:在马尼拉草地及茶梅灌木地上覆盖松针、核鳞、树皮及枯叶保水效果显著,其中,在马尼拉草地上覆盖树皮的保水效果最好,而茶梅灌木地上覆盖枯叶的保水效果最好;覆盖木屑的保水效果较差,其土壤含水量比对照的低。由此可知,松针、核鳞、树皮及枯叶是很好的土壤保水材料。Through indoor potted tests, we studied the effects of covering the ground with 5 kinds of organic materials （ saw- dust, pine needle, nuclear squama, bark, dried leaf） on soil moisture of urban landscape plants. The results showed that covering Manila grassland and Camellia sasanqua shrub land with pine needle, nuclear squama, bark and dried leaf had significant water - retaining effects, and covering Manila grassland with bark and covering Camellia sasanqua shrub land with dried leaf had the best effects. The water retention effect of covering with sawdust was the poorest, and its soil moisture content was lower than that of the control. In conclusion, pine needle, nuclear squama, bark and dried leaf are good water - retention materials for soil.
