摘要:
以吉育47大豆为材料,研究不同生育时期灌水处理对内蒙古干旱半干旱地区大豆根系性状动态变化及产量的影响。结果表明,大豆分枝期或开花期灌水,可增加根系鲜重、增强根系活力、增大根系活跃吸收面积;全生育期灌水可增加根系鲜重,增大根系吸收面积,降低根系活力,而全生育期不灌水处理恰好相反。在仅灌一次水的情况下,以大豆分枝期灌水处理产量最高,达2 305.5 kg·hm-2。
Abstract:
The effect of irrigation at different growth stages on root dynamic changes and yield of soybean in arid and semi-arid regions in Inner Mongolia was investigated with soybean cultivar Jiyu 47 as material.The results showed that irrigation at branching or flowering could significantly increase root fresh weight,enhance root activity,and enlarge root active absorption area.Irrigation during whole growth period increased root fresh weight and absorption area,decreased root activity;while no irrigation treatment had opposite results.On the condition of irrigated one time during whole growth stage,the highest yield of 2 305.5 kg·ha-1 was achieved when irrigated at branching stage.
