[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。

[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 gradual-ly, 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...
