| 摘 要： | 通过对滴灌带灌水均匀度的田间实际测试，结果显示：当滴灌带铺设长度（Ｌ＝１２０ｍ）较小时，所测试产品的灌水均匀度（＞９５％）都很高，随着滴灌带铺设长度（Ｌ＝２４０ ｍ即流量）的增加，其灌水均匀度（＜９０％）逐渐减小；另一方面，随着滴灌带入口压力（１３．７９ｘ１０~４Ｐａ）的增加，其灌水均匀度（>８６％）随之增加。

| Abstract: | The experiment about irrigation equality degree of dripline PC has been carried out in the field. It shows that the value of the irrigation equality degree is higher when the length of dripline PC is shorter, that the value gradually declines with increasing the length, while rises with the dripline PC inputting pressure being increased. |
