【目的】湖北平原湖区6—7月降雨较多,因此,需合理利用降雨资源,确定雨后田间适宜蓄水深度。【方法】结合湖北平原湖区生产实际,针对中稻机插秧和直播2种播种方式,在中稻分蘖期进行了不同蓄水深度(4、8、12和16 cm)测坑试验。【结果】当模拟机插稻蓄水深度4 cm、直播稻蓄水深度8 cm时,水稻叶片的光合速率最高,10~20 cm土层的根系干质量最大,产量最高;对模拟机插稻,蓄水深度8、12、16 cm的处理,产量较4 cm处理分别降低3.75%、9.49%和11.97%;对直播稻,蓄水深度4、12、16 cm的处理,其产量较8 cm处理分别降低5.03%、12.87%和16.45%。【结论】在本试验所研究的蓄水深度下,模拟机插稻与直播稻在分蘖期适宜的蓄水深度分别为4 cm和8 cm。当遭遇大...
