FIELD: agriculture, in particular, viniculture.
SUBSTANCE: method involves taking samples for refraction metering of cellular sap of indicating organs of vines from different parts of vineyard; determining cellular sap concentration by means of field refractometer; working out regression analysis diagram of dependence between content of soil moisture accessible for plants and refractometric factor value of cellular sap concentration of indicator organ for obtaining of "soil-sort" combination, said diagram being provided with additional irrigation norm scales for different vine growing periods. Indicator organs are 2-3 apex top internodes of green sprouts selected on the basis of refractometric factor value of cellular sap concentration and allowing moisture content of plants to be determined. According to diagram, irrigation time for vineyard is designated without allowing cellular sap concentration of indicator organ to be increased to critical level.
EFFECT: increased precision in diagnosing under field conditions of grape moisture content and designating of vineyard irrigation time.
