[0002] Drip irrigation pipe is to use plastic pipe (drip irrigation pipe) to send water to crop root part through the orifice or dripper on the pipe of about 10mm diameter to carry out local irrigation. Drip irrigation pipe uses low pressure pipe system to send water to field, and then through the dripper, orifice or drip irrigation pipe irrigation device installed on the pipe, water is dripped into the soil near the crop root zone evenly and slowly, so that the soil of the most developed area of crop root system keeps the suitable humidity.

[0003] During the long time use of drip irrigation pipe, various impurities that water source may contain, such as suspended solids, dissolved solids, microorganisms, etc. will affect the normal operation of drip irrigation pipe to some extent. Especially when the water contains high calcium and magnesium ions, these ions may react to form water scale that is difficult to dissolve during flowing in the drip irrigation pipe due to the change of temperature, pressure, flow rate and other conditions. These water scale will gradually accumulate on the inner wall of the drip irrigation pipe and the dripper, causing the water flow channel to narrow, and even completely block, thereby affecting the irrigation efficiency and effect of the drip irrigation pipe.

[0004] In order to prevent the water scale from gradually accumulating on the inner wall of the drip irrigation pipe and the dripper, a series of drip irrigation pipe water quality regulators are usually used at home and abroad to prevent and dissolve these water scale. Although these water quality regulators show potential in preventing and dissolving water scale to some extent, the existing laboratory test method is difficult to accurately evaluate their effect in actual application.
