| 摘 要： | 为制定玉米节水高效灌溉制度,推动节水农业的发展,采用试验测桶研究了黔中地区玉米产量与水分的关系。结果表明,玉米生育期内平均水分利用效率为1.32 kg/m3,产量和灌溉水量之间的函数式y=-0.000 3x2+3.794x-2 792.7,产量与耗水量之间的函数关系式y=-0.000 6x2+7.215 4x-13 286;水分亏缺的敏感指数以抽穗-灌浆期最高,为0.178,其次是拔节-抽穗期,为0.164。 |

| Abstract: | The effects of different irrigation volume on growing development and yield of maize were studied to formulate the water-saving and efficient irrigation system for maize production and promote the development of water-saving agriculture.The results showed that the mean water use efficiency of maize plants was 1.32kg/m2 in the whole growth period,the equation between yield and irrigation volume was y=-0.0003x2+3.794x-2792.7,the equation between yield and water consumption was y=-0.0006x2+7.2154x-13286,and th... |
