Abstract

The article proposes a scheme of drip irrigation for growing vegetables in the backyard. In the conditions of change of climatic conditions, the question of lack of moisture sharply arises. For growing vegetables in areas of risky agriculture, irrigation is an important condition for obtaining high yields. In order to increase the technological efficiency of growing vegetables at the department of general agriculture of the Central Ukrainian National Technical University developed a prototype of a drip irrigation system for vegetables. A series of studies was conducted to provide moisture to the site and preserve soil air exchange. With the use of conventional irrigation, possible negative consequences in the form of soil flooding, the root system of plants is not able to develop evenly and is deficient in oxygen. The calculation and the scheme of drip irrigation of tape type are offered. In the proposed design for drip irrigation of the area under vegetable crops used a container with water to provide a small constant water pressure in the strips. This made it possible to water as needed, as well as to use a solution tank to feed the plants, protect them from stress, improve development and increase yields. The use of drip splicing allowed the first fruits to appear a decade earlier and increase yields by 25-50%. The use of drip tape irrigation system on the experimental plots allowed to increase the quantity and quality of tomato harvest. Also, the use of drip irrigation allowed to maintain the optimal water-physical regime in the root layer of the soil, which created the conditions for a better harvest. Thus, with the change of climatic situation, most of the Kirovohrad region was looking for in the zone of risky agriculture. Drip irrigation has an almost universal application, is effective in intensive technologies for growing crops and ornamental crops, as well as in garden areas, when the condition of the plant largely depends on the accuracy of maintaining the humidity and nutrition of plants.
