METHOD FOR CONTROLLING IRRIGATION AMOUNT IN SOILLESS CULTURE

摘要

The present invention relates to a method for controlling the supply amount of a culture medium in cultivation of a non-soil cultivation of a crop, comprising the steps of: measuring a light intensity received by the crop and an amount of the crop growth, A data collecting step of collecting data of luminous intensity and a quantity of evaporation; A relational expression determining step of determining a relational expression through a correlation between the luminous intensity and the amount of vaporized light collected in the data collecting step; And a culture solution supplying step of supplying the culture solution to the crop according to the cumulative irradiation dose calculated by applying the relational expression. According to the method of controlling the supply amount of the culture liquid of the present invention, it is possible to improve the efficiency of the irrigation water by accurately estimating the supply amount of the culture liquid by compensating the luminosity value by precisely determining the relationship between the luminosity and the transpiration amount in non- There is an effect that the excessive supply of the culture liquid is controlled.
