TECHNOLOGY, HARDWARE AND DESIGN OF AN AUTOMATED STATIONARY-SEASONAL SYSTEM OF OVERTREE MIST SPRINKLING
The introduction of gardening with low-growing plantations required the development of an aerosol humidification toolkit. Such a set must meet modern requirements for gardens’ cultivation with automation of the process of periodic and repeated moistening of the surface air layer and leaf surface of plants. The purpose of the research was to create a set of overtree mist sprinkling to produce a fine rain of small drops with diameters of less than 500-700 mm and an intensity of less than 0.01 mm/min. The set of the system of pulse spray dampening (KAU-1M), which was developed by the authors, includes: some rack sprinklers with spray nozzles (mast), supply, distribution and irrigation pipelines, node automatic control of water supply, including hydraulically controlled valves with hydraulic switch software. This set has an irrigation area of 1 ha and is a module to build combined systems with drip irrigation and sprinkler irrigation. In accordance with the trends of low-growing gardening development, the design of the system of fine-dispersed sprinkling with a reduced height of masts up to 5 m was developed. This system does not require the use of special mechanized means for its installation. An automated control system for dispersed water supply is proposed. This system allows with high accuracy (?0,2 sec) to set and implement a wide range of the pulses duration (from 1 min and more) and pauses between them - from 1 min. The maximum single rate of water supply to eliminate the depression of photosynthesis in the developed design can reach 3,6 m3/ha per hour, taking into account that previously recommended doze was 0,1-0,6 m3/ha per hour. The objective of the research is to assess the potential of satellite services for solving agricultural monitoring problems
