| 1、首先从外观来讲滴灌带在没有水和压力的情况下是扁平状态，而滴灌管则是圆柱形的； 1. First of all, the drip irrigation belt is flat without water and pressure, while the drip irrigation pipe is cylindrical. 2、其次从滴头形式来进行分别，滴灌带一般是内镶扁平低头，滴灌管则是内镶圆柱形式的滴头； 2. The drip irrigation belt is usually inlaid with flat bow, and the drip irrigation pipe is inlaid with cylindrical emitter. 3、使用时间，滴灌带相比较于滴灌管壁厚较薄，使用时间短，滴灌管的使用时间要长； 3. Compared with drip irrigation pipe, drip irrigation belt has thinner wall thickness, shorter using time and longer using time. 4、出水量的大小，滴灌带的出水量是2L/h左右，滴灌管出水量是3L/h左右。滴灌管的出水量要大于滴灌带； 4. The amount of water produced is about 2L/h of the drip irrigation belt and the water yield of drip irrigation pipe is about 3L/h. The output of drip irrigation pipe is larger than that of drip irrigation belt. 5、投入资金方面，滴灌管的资金投入要高于滴灌带。 5. In terms of investment, the investment of drip irrigation pipe is higher than that of drip irrigation belt. |
