Low pressure trickle irrigation is based on the little effect of pressure on the quality of drip irrigation system
壓力水頭對滴灌系統的灌水質量影響很小，這為低水頭滴灌提供了理論依據。 -
Low pressure trickle irrigation is popular with farmers. currently, the study direction of drip system is to develop low pressure emitters
當今，研製大流量的壓力補償式灌水器是低壓滴灌研究的方向。 -
When the area of little irrigation district is constant, drip line of trickle irrigation has the optimizing length. if the length of drip line is longer or shorter than the optimizing length, the expense of trickle system increases
一般認為，毛管長度越長，則滴灌系統造價相應就會減少，因此，在優化設計時，通常認為毛管取最大長度。 -
When other factors are unchangeable, with the growing of the diameter of drip line and the distance of emitters, irrigation uniformity of trickle system is increasing. the face gradient of little irrigation district has complex effect on irrigation uniformity. in a word, we tries our best to make the face of little irrigation district flat in order to improve the quality of drip - irrigation system
灌水均勻度由某一因素決定，而其它因素不變的條件下，隨管徑增大，滴灌系統的灌水均勻度增大；隨滴頭間距增大，灌水均勻度也在增大；地形坡度對灌水均勻度影響比較復雜，為了提高低壓滴灌的灌水質量，土地必須整平。
