摘  要:
[目的]研究水稻分蘖期生理耗水量,以期更加高效地节约灌溉水资源。[方法]采用室内盆栽方法,对水稻进行控水灌溉,根据每天每试验盆重量变化分析水稻生理耗水量。[结果]水稻分蘖前期耗水量不断增加,到分蘖后期逐渐降低,水稻分蘖前期平均每株每天耗水193.75 g,水稻分蘖后期平均每株每天耗水260.92 g。每盆栽2株水稻耗水量高于每盆栽1株水稻耗水量33.4%。[结论]在水稻分蘖末期应控制灌溉水量;水稻种植越密,分蘖期生理耗水量小,其分蘖数相应减少。

摘  要:
[Objective] To research the physiological water consumption of rice in tillering stage,and to save irrigation water resources more effectively. [Method] Indoor potted method was used for water control irrigation of rice. According to the weight changes of each test pot in each day,physiological water consumption of rice was analyzed. [Result]Water consumption in early tillering stage of rive increased gradually,and then reduced in late tillering stage. The average daily water consumption per day of rice was 193. 75 g in early tillering stage,and that was 260. 92 g in late tillering stage. The water consumption per plant of two plants per pot was 33. 4% higher than that of one plant per pot.[Conclusion]Water irrigation should be controlled in late tillering stage of rice. Dense planting rice leads to small water physiological water consumption in tillering stage; and the tiller number reduced correspondingly.
