| 摘 要： | 通过室内盆栽试验,研究了生活废弃物、茎秆类植物、条状类植物和阔叶类植物4种有机物材料覆盖土壤表面对土壤水分蒸发的影响。结果表明,4种有机物覆盖均能达到抑制土壤水分蒸发、提高水分利用率的目的,抑蒸效果均随覆盖量的增加而提高。以棉花叶为代表的阔叶类植物对土壤水分的抑蒸效果最好,其他3种覆盖材料抑蒸效果依次为条状类植物>茎秆类植物>生活废弃物。覆盖抑蒸效益分析表明,茎秆类和条状类植物在覆盖量为4 000.2 kg/hm2、废弃物和阔叶类植物在覆盖量为2 000.1 kg/hm2时,抑蒸效益最好。 |

| Abstract: | Pot experiments were conducted to investigate the effects of 4 kinds of organic materials（domestic waste,stem-type plants,strip-type plants,and broad-leaf plants） as mulches to soil water evaporation.The result showed that all these 4 organic materials inhibited effectively soil moisture evaporation and improved water use efficiency,and their inhibitory effects were increased with the increasing of coverage amount.The best water-inhibiting result was obtained by using the broad-leaf plants as mulch,which was represented by cotton leaves,and the inhibitory effect of the other three kinds of organic mulching materials followed by strip-type plants〉 stem-type plants〉 domestic waste.The analysis of water inhibitory benefit on different treatments showed that the better results can be obtained when the amount of mulch were 4 000.2 kg/hm^2 stem-type of strip-type plants,and 2 000.1 kg/hm^2 domestic waste or broad-leaf plants. |
