| 摘 要： | 在蒸渗仪中模拟烤烟全生育期1000mm,800mm,600mm共3种降雨量,研究烟田的水分平衡状况,探讨不同降雨量条件下烤烟各生育期的蒸散量、蒸腾量、棵间蒸发量和烟株水分利用效率的变化。结果表明,当模拟降雨量为800mm时烟田水分处于动态平衡,既满足烤烟各生育时期生长所需要的有效水分,又提高了水分的利用效率,烟叶产量较高。

| Abstract: | The water balance in tobacco fields was studied by simulating rainfall of 1 000 mm,800 mm,and 600 mm in a lysimeter over the whole growth period of tobacco plants.The variations of evapotranspiration,transpiration,ground evaporation between plants,and water use efficiency of tobacco plants were analyzed under different rainfall conditions during various growth stages of tobacco plants.The results show that rainfall of 800 mm could keep a dynamic equilibrium of water in the tobacco fields,and it could meet the needs of effective water of tobacco during various growth stages improve the water use efficiency,and thus increase the yield of tobacco. |
