流す。With the above construction, the stock solution having a high fertilizer concentration is diluted with water to become a nutrient solution having a predetermined concentration. This nutrient solution is supplied to each culture medium of the crop through a plurality of drippers 14 at a predetermined time or according to the demand of the crop. When the supply of the nutrient solution is completed, water is supplied to each dripper 14 for several seconds or minutes, and the nutrient solution adhering to the dripper 14 is washed away by the water.

The nutrient solution is pumped out by the pump 8 and then filtered. After passing through the flowmeter 10 and the solenoid valve 11, it is guided into the house 12, and each of the drippers 14 is guided by a plurality of thin tubes 13.
Is supplied to the medium through. Each dripper 14 has a star-shaped cross section, and the nutrient solution flows down through the grooves on the outer periphery thereof. As shown in FIG. 2, the medium is made up of a ridge-shaped ground 15 covered with a vinyl sheet 16 and a rock wheel 17 placed thereon. Then, a sponge 18 for holding the roots of the seedlings is placed on the lock wheel 17, and the lower end of the dripper 14 is inserted into the sponge 18 (and the lock wheel 17).

る。As shown in FIG. 3, a control computer 19 is provided. The control computer 19 operates the pump 8 and the electromagnetic valve 11 at predetermined intervals to intermittently supply the nutrient solution to the respective drippers 14. The signals of the EC sensor 6 and the PH sensor 7 are introduced into the control computer 19, and the signals are used to control the solenoid valves 2a, 3
a and 4a are activated to adjust the concentration and PH value of the nutrient solution in the mixing barrel 5 within a predetermined range.

It was designed to be water only for the few seconds before. Therefore, the pump 8 is instructed by the control computer 19.
When the solenoid valve 11 starts to operate, the control computer 19 operates the solenoid valves 2a, 3a, 4a by the signals of the EC sensor 6 and the PH sensor 7, and the mixing barrel 5
The nutrient solution is supplied to the sponge 18 (and the rock wheel 17) through the thin tube 13 and the dripper 14 while adjusting the concentration and pH value of the nutrient solution therein. And
Prior to the suspension of the pump 8 and the solenoid valve 8, the solenoid valve 2
Supply of stock solutions A and B is stopped at a and 3a. Therefore, the nutrient solution intermittently supplied to the rock wool 17 is water only for a few seconds before the rest, and the fertilizer components adhering to the respective drippers 14 are washed away with this water.

る。The solenoid valve 8 may be a variable opening solenoid valve. Then, for example, the liquid pressure in the thin tube 13 was 2 atm when the normal nutrient solution was supplied, but rises to 3.5 to 4 atm when the solenoid valve 8 is fully opened. Then, if the solenoid valve 8 is set to be fully opened only for a few seconds at the start of supplying the nutrient solution, the concentration may increase in the thin tube 13 during the suspension of the nutrient solution supply, and the flow may be blocked. This clogging is pushed out with a high pressure, and the supply amount of the nutrient solution in the normal state is stabilized.

An inverted U-shaped support leg 46 extends downward from both ends of the horizontal bar 43, and a roller 47 is rotatably attached to a lower end of the horizontal bar 43 by a shaft 48. Roller 47 rides on purlin 44,
The horizontal bar 43 is moved by the rotation of the roller 47. An operator can move the horizontal bar 43 to a predetermined place and use it like a handrail to safely work. Figure 1
0, a rain gutter 49 is provided at the lower ends of the glasses 45, 45 in FIG.
