emitter discharge rate 灌水器流量
For the same emitter discharge, the cotton with sufficient water supply has higher evapotranspiration than that with deficient water supply.
在滴头流量相同时，充分供水时棉花的总蒸散量高于非充分供水。
The result shows that under the same conditions, low-discharge drip irrigation strap's emitter discharge has a little change along the distance.
试验结果表明：在同一坡度及同一铺设长度下，不同规格的滴灌带滴头流量随压力的增大而增大；
