Special features of drip-sprinkler irrigation technology

Irrigation techniques and technology based on principle of regular accumulation of moisture in active layer (surface irrigation, regular sprinkler irrigation) are most common in science and in practice. More progressive is principle of non-stop water supply of plants and soil in conformity to their water consumption. Drip irrigation and impulse sprinkling are based on this principle. The main advantage of drip irrigation is establishment of optimal water and nutritive regime directly in the plant root system. However, such irrigation is not effective enough under conditions of high air temperatures (over 25–35 °С), as growing process of several agricultural plants is known to slow down at 30–35 °С and photosynthesis, consequently, stops, which, in turn, affects plants yielding capacity. Sprinkling irrigation provides improvement of both microclimate in plant's environment and their water regime. Combination of drip and sprinkling irrigation permits the positive characteristics of each individual technology to be united, and to remove a series of disadvantages of their separate use as well as to use drip-sprinkler irrigation technology to create optimal conditions for plant development. Drip-sprinkler irrigation technology facilitates saving of irrigation water through drip irrigation in the main vegetation period and through improvement of microclimate and water regime of agricultural plants with additional sprinkling irrigation within the period of high temperatures and low air humidity that affects the growing process and increases yielding capacity of grown cultures.
