| 摘 要： | 田间试验研究秸秆覆盖对红壤旱地间作生态系统小气候的影响结果表明,红壤旱地实施秸秆覆盖后湍流交换热通量增大、潜热交换热通量和土壤热通量变小,且使秸秆全覆盖和半覆盖处理近地面温度和土壤湿度增高、土壤温度和近地面湿度降低,秸秆覆盖具有蓄水保墒和低温效应。

| Abstract: | The impact of stalk(mulching) on the microclimate of intercropping ecosystems in upland red soil was studied(through) field experiments.Stalk mulching can increase the flow caloric flux,decrease the soil caloric flux and laent caloric flux in upland red soil.As a result,air temperature near the ground and soil humidity are enchanced,soil temperature and humidity near the ground are declined.Stalk mulching has the effects of keeping the soil moisture and lowering the ground temperature. |
