Description
Technical Field
The invention belongs to the technical field of irrigation devices, and particularly relates to a high-uniformity multi-cavity drip irrigation tape.
Background
Drip irrigation is the most effective water-saving irrigation mode at present, and the water utilization rate can reach 95%. Compared with spray irrigation, the drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to improve the fertilizer efficiency by more than one time. The drip irrigation is a water irrigation method for uniformly and slowly dripping water and nutrients required by crops into soil in a crop root zone one drop by one drop through a pipeline system and an irrigation device arranged on a capillary according to the water requirement of the crops. The drip irrigation does not damage the soil structure, the water, fertilizer, gas and heat in the soil are always kept in good condition suitable for the growth of crops, the evaporation loss is small, no ground runoff is generated, and deep seepage is hardly caused, so that the drip irrigation is a water-saving irrigation mode. The drip irrigation device is mainly characterized by small irrigation quantity, the flow rate of the irrigation device per hour is 2-12 liters, so that the one-time irrigation duration is longer, the irrigation period is short, the small-water frequent irrigation can be realized, the required working pressure is low, the irrigation quantity can be accurately controlled, the ineffective interplant evaporation can be reduced, the waste of water can not be caused, and the drip irrigation can be automatically managed.
The core component of the drip irrigation system is the drip irrigation tubing, i.e., the drip irrigation pipe/tape. Drip irrigation pipes/belts are used to deliver water through plastic pipes (drip irrigation pipes) to the roots of crops for local irrigation through orifices or drippers of about 10mm in diameter on the capillary. Drip irrigation pipes/belts are mainly divided into inlaid drip irrigation belts and side seam drip irrigation belts. The embedded drip irrigation tape is a drip irrigation tape in which a prefabricated dripper is embedded in a capillary in the manufacturing process of the capillary, such as an embedded patch type drip irrigation tape and an embedded cylindrical drip irrigation pipe. The edge-seam drip irrigation tape is characterized by that when the thin-wall pipe is made, the drip outlets with various shapes of pressure-reducing flow channels are made up by means of heat-sealing treatment on one side or middle portion of the pipe, for example, a single-wing labyrinth drip irrigation tape.
An important index for evaluating the irrigation quality of a drip irrigation system is the irrigation uniformity, at present, all capillary tubes adopt one end for supplying water, the water yield of the capillary tubes is gradually reduced from beginning to end and is controlled by the uniformity requirement, the capillary tubes are arranged to have a limit length, and meanwhile, the limit length of the capillary tubes is greatly reduced due to the slope (particularly an ascending slope or a reverse fracture).
Along with the increase of the length of the capillary, the head loss of the capillary is increased, and the uniformity of the discharged water is reduced. Especially under the condition of slope, especially when the capillary is arranged in an adverse slope, the working pressure difference of the dripper is not only influenced by the loss of the capillary along the way and the local water head, but also the gravitational potential generated by the terrain height difference becomes a part of the working pressure influencing the dripper, so that under the same dripper water head difference requirement, the length of the capillary becomes very short, the number of branch pipes is increased, and the operation and the management of the system are not changed.
