Abstract

To ensure the optimal water-air balance of the plant, agro-reclamation measures are required, including the organization of irrigation. The advantage of drip irrigation is the most rational consumption of irrigation water. To realize this advantage, it is necessary to calculate the irrigation rate taking into account the dynamics of moisture distribution in the soil. During irrigation, the humidification circuit takes on a semi-elliptical shape. To determine the geometrical parameters of the humidification circuit, one should take into account the physical and mechanical properties of the soil and irrigation water, the mineralization of which varies widely. Having identified the numerical dependences and the nature of the distribution of moisture in the soil and having calculated the parameters of the irrigation circuit, it is necessary to determine the flow rate per dripper and subsequently calculate the irrigation rate, taking into account all of the above factors. The proposed method for calculating the irrigation contour will make it possible to rationally use water for irrigation, minimizing losses due to filtration into deep soil layers. Optimizing the water regime of plants during the growing season will not only save water and energy resources, but also maintain an optimal water and air regime, which will increase the yield and improve the quality of grown products.
