PURPOSE:To separate a unit device of a raw chaff-receiving, filtering and solution-discharging means from a device group in the case of disease of plant by setting the device group so as said means composed of at least single unit or each block to be separable from any position of the device group. CONSTITUTION:A light-shielding water spraying means having a plant inserting hole 19 is connected with a light-shielding water spraying and solution supplying port 20 by thrusting with each other and nourishing solution in the area of dotted line is dropped. The light-shielding water spraying and solution supplying means is received in a raw chaff-receiving, filtering and solution-discharging means and connecting pins 27 are inserted in connecting holes, then the two raw chaff-receiving, filtering and solution-discharging means are connected with each other, thus raw chaff 1 is received and a plant supporting and fixing means is installed, then solution-discharging ports 13 of the chaff-receiving, filtering and solution-discharging means are connected with a joint 28. |
