METHOD OF CONTROLLING PHYTOCLIMATE IN GRAPHITE-CENOSES UNDER DRIP IRRIGATION AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC A01G25/00 A01G25/02 

FIELD: agriculture.

SUBSTANCE: method includes periodic irrigation of root habitable horizon, periodic moistening plants, determination of the surface air temperature, the temperature of plant leaves and relative humidity of the surface air. The values of the coefficients A, B, C are calculated by formulas. At A≥0.9 the drip irrigation is performed with a rate of 150-200 m³/ha from 22 pm to 2 o'clock at night. At B≥1.2 with dry winds from 11 to 15 o'clock in the afternoon the surface air is irrigated with atomization of water particles with a diameter of 10-50 micron with replaceable nozzles. At C≥1.5 the leaves and stems of plants are additionally moistened with water droplets with a diameter of 100-800 micron for 3-4 hours. At A+B≥2.1 drip irrigation is carried out to reduce the soil temperature +22…26°C, and the relative air humidity is increased to 50…70%. At B+C≥2.5 the agricultural plants leaves and the surface air is moistened by atomisation of irrigation water for 0.5 h with intervals every hour. At A+C≥2.5 drip irrigation is carried out for 2-3 hours, and the agricultural plants leaves are moistened. At A+B+C≥3.5 drip irrigation is carried out for 30-45 minutes at intervals of 2 hours. The system comprises water source, a pumping station with filters and irrigation network in the form of irrigation pipelines with droppers. The system is equipped with an additional water distribution pipeline which is hydraulically connected by flexible irrigation pipelines having droppers. Each rack for periodic moisturising of low- and middle-growing plants is made in the form of rods of circular section. The upper ends of the rods are connected by the adapter. The adapter has a nipple on one side for hydraulic connection with a fitting placed in the wall of the flexible irrigation pipeline with droppers. The fitting is located in the wall of the flexible irrigation pipeline with droppers. The adapter is connected to the conical cavity of the nozzle with a conical sleeve.

EFFECT: preservation of the cultivated harvest under critical conditions is provided.
