Supplying the dilution liquid fattening/fertilizing

摘要

PROBLEM TO BE SOLVED: To grow all of crops in ideal states by feeding a diluted liquid fertilizer in an ideal state into a plurality of groups of a distribution line while preventing the plugging of the distribution lines effectively.;SOLUTION: This method for feeding the diluted liquid fertilizer includes supplying the diluted liquid fertilizer to the crops by repeating: the process of filling water of feeding water to a discharging line 2 linking the distribution lines 1 and filling the discharging line 2 and distribution lines 1 with water; the liquid fertilizer-feeding process of feeding the predetermined amount of the diluted liquid fertilizer to the discharging line 2, discharging the water in the discharging line 2 from the tip end part, after discharging the water in the discharging line 2, stopping the discharge of the water from the tip end part, feeding the diluted liquid fertilizer fed to the discharging line 2 to the distribution lines 1, and feeding the diluted liquid fertilizer to the crops by the distribution lines 1; and, after the liquid fertilizer-feeding process, the water-filling process of feeding the water to the discharging line 2, transferring the diluted liquid fertilizer in the discharging line 2 to the distribution lines 1 by the fed water, and further feeding the diluted liquid fertilizer in the distribution lines 1 to the crops and filling the distribution lines 1 and discharging line 2 with the water.;COPYRIGHT: (C)2011,JPO&INPIT
