Release Date:

2019-10-09

To begin, let’s introduce drip irrigation. Drip irrigation involves the use of a range of advanced drip-irrigation equipment, including drip tapes, drip pipes, and pressure-compensated emitters. For cucumber cultivation, patch-type drip tapes or drip pipes are typically employed. A complete drip-irrigation system comprises four main components: the water source, the headworks, the water-delivery and distribution network, and the end-of-line drip-emitter devices. The water source must be clean; accordingly, filtration equipment is installed as needed. Although drip irrigation is classified as low-pressure irrigation, this does not mean that pressure is unnecessary. Under normal operating conditions, a working pressure of about 0.1 MPa is sufficient; however, prolonged operation at excessively low pressures can readily lead to clogging of the drip-irrigation system.

Subsurface Drip Irrigation for Cucumbers This refers to laying a layer of plastic mulch over the drip irrigation system—after the drip tape or drip pipe has been installed—to provide insulation and moisture retention. When using subsurface drip irrigation in open fields, it is also important to remove hard clods, stones, and weeds from the soil surface to prevent the mulch from bulging; otherwise, water droplets on the film may focus sunlight and scorch the drip tape or drip pipe.

In addition, cucumber drip irrigation can be integrated with fertilization—using venturi injectors, fertilizer tanks, or fertilizer injection pumps—to achieve fertigation, reduce labor input, and ultimately increase both yield and income.
