Technological process of water intake with layered drainage

Summary. This article is aimed at the analysis and creation of new reclamation systems for irrigation of agricultural products associated with climate risk. The scientific novelty is determined in the solution of the proposed irrigation system with a submersible water intake device.

Introduction. The optimal value of the water temperature for irrigation is 18... 22 degrees. The temperature of the water from the well does not exceed the threshold of 7... 9 degrees. This will not benefit the plants. According to scientists, the temperature difference between soil and water for irrigation should not exceed 5 degrees. Therefore, it is advisable not only to measure the temperature of the water, but also to ensure that containers are available in irrigation areas to warm it up. This approach is especially necessary when irrigating seedlings.

Object. Based on existing irrigation equipment and technological processes for growing vegetable crops in the open ground, we offer a technology for water intake of irrigation water from different depths of the reservoir.

Materials and methods. The proposed experimental technology of water intake from different depths is necessary for watering plants with water with different values of optimal temperature. The experimental system also includes materials from previous developments of float water intake devices, an air cushion for regulating the depth of irrigation water intake and scientific materials accumulated by VNIIGiM scientists.

Results and conclusions. The article analyzes and makes recommendations on the creation of new reclamation systems for irrigation of agricultural products associated with climate risk. The scientific novelty is determined in the solution of the proposed irrigation system with a submersible water intake device. The submersible device is used to take water from a depth of 0.5...2.5 meters from the mirror of the water surface. At the same time, in the irrigation season, the temperature of the irrigation water depends on the depth of immersion. The deeper we pump the water, the colder it is, and vice versa, the closer to the water mirror, the warmer it is. Thus, our technology is aimed at taking water of different temperatures, depending on the depth of immersion of the float intake device, for irrigation of cultivated plants.
