Zusammenfassung:The invention relates to viticulture, namely to a process for protecting the grapevine from adverse weather conditions.The process, according to the invention, provides for the partial or total coverage of plants with a thermo-insulating coating, comprising silicone microspheres of a diameter of 50...80 µm and ceramic microspheres of a diameter of 10...30 µm, in a ratio of 1:4, and an acrylic binder. At the same time, the coating is applied at an ambient temperature of at least +7°C, on dry surface, by submersion, spraying or brushing in 1...2 layers of a thickness of 0.1...0.5 mm, the duration of drying of each layer being of 24 hours.The result is to simplify the mode of application of thermo-insulating coating. Invenţia se referă la viticultură, şi anume la un procedeu de protecţie a viţei-de-vie împotriva condiţiilor meteo nefavorabile.Procedeul, conform invenţiei, prevede acoperirea parţială sau totală a plantelor cu un înveliş termoizolator, care conţine microsfere de silicon cu diametrul de 50...80 µm şi microsfere de ceramică cu diametrul de 10...30 µm, în raport de 1:4, precum şi un liant acrilic. Totodată, învelişul se aplică la o temperatură a mediului ambiant de cel puţin +7°C, pe suprafaţa uscată, prin înmuiere, pulverizare sau cu pensula în 1...2 straturi cu grosimea de 0,1...0,5 mm, durata de uscare a fiecărui strat fiind de 24 ore.Rezultatul constă în simplificarea modului de aplicare a învelişului termoizolator.
