　　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.
