PROSPECTS OF DRIP IRRIGATION OF VEGETABLES WITH THE USE OF ELECTROCHEMICALLY TREATED WATER AND SOLUTIONS

Topics: 06.01.02 Land Reclamation, Recultivation, and Land Protection

Abstract:

The aim of the research was to evaluate the effectiveness of the use of modern designs of drip irrigation for irrigation of vegetable crops with water or solutions with electrochemically initiated redox-processes. The methodological basis of the research was the results of many years of theoretical work, the conceptual provisions of the method of designing technical irrigation systems with electrochemically treated water and solutions, the main provisions of the method of experimental research. The options of drip irrigation structures that provide control and supply of irrigation water with the specified parameters of pH and redox potential are considered in the article. It is indicated that the introduction of the drip irrigation technical systems of the flow module of electrochemical processing into the structure requires the electrochemically initiated redox-processes dynamics control and the preservation of electrochemical potentials in accordance with agrotechnical requirements of the culture in addition to the known condition of water distribution uniformity. An example and the results of the production calculation of drip irrigation system with the mode of electrochemical treatment of irrigation water are given. The possibility of matching the functional criteria of the system on the basis of a systematic approach with the design of all points of the drip irrigation system without exception is shown. The effectiveness of electrochemically treated water both for irrigation and fertigation is shown by the example of tomatoes in protected ground using the drip irrigation system with the module of electrochemical treatment designed according to the proposed method. It was found that to obtain the highest yield of tomatoes (at the level of 133.1–146.5 ton per ha) using electrochemically treated water it is necessary to carry out both moistening and fertilizing irrigation and the level of displacement of the oxidation-reduction potential at the outlet of drip water spillways should be at least minus 500 mV.
Keywords: drip irrigation, electrochemical treatment, design, calculation, tomatoes, efficiency.
