| Abstract: | On the basis of lysimeter data and field experiments,the soil temperature and moisture profiles as well as their temporal processes with and without plastic or straw mulch have been studied,and the characteristics of soil evaporation,water recharge and recession have been studied on the basis of accurate observation data of water balance elements during different plant growing periods.The effects of production enhancement and water saving by the mulch under different groundwater tables have been demonstrated,and that highlights the importance of mulch in the controlling of soil evaporation and water saving as well as the use of soil water resources and precipitation resources. |
