摘要： 试验研究了浅湿干灌溉、间歇灌溉、好气灌溉等3种大田节水灌溉方式对水稻群体生长特性的影响。结果表明，节水灌溉延迟了水稻分蘖进程，分蘖数较常规灌溉不同程度增加，增幅为27～54茎/m2；水稻成穗率较常规灌溉有所提高，增幅分别为3.2%、13.9%和12.8%；水稻根干质量和根冠比均高于常规灌溉。

Abstract: The effects of 3 water saving irrigation models namely shallow-wet-dry irrigation, intermittent irrigation and aerobic irrigation on population growth characteristics of rice were studied. The results indicated that the tillering process was delayed, tiller number was increased by 27～54 tillers/m2 compared with conventional irrigation. The spike rate were increased by 3.2%, 13.9%, 12.8% respectively. Root dry weight and root shoot ratio were higher than conventional irrigation.

Key words: water saving irrigation, cold area, rice, population growth characteristics
