CONSTITUTION:Plural rock fiber blocks 1 are continuously arranged to form a culture medium 2 and frames 3 in a recessed form of U-shaped cross section are placed along at positions toward one side on the top surface of the culture medium 2. An irrigation water supply pipe 5 having many discharge holes 4 on the undersurface is arranged at a position of the opening surface of the recessed part in parallel with the above-mentioned frames 3 in the recessed form. A filter medium 8 consisting of a polyester nonwoven fabric is laid in the frames 3 in the recessed form, extending to the outside. Slow-release fertilizer grains 9 are placed thereto to constitute a fertilizer applicator. Nursery beds 11 in which tomato seedlings 10 are planted in rock fiber blocks 1 are placed in the central part of the top surface of the culture medium 2 and the top surfaces of the nursery beds 11] are removed to cover the whole culture medium with silver polyethylene sheet (silver sheet) 12 containing Al foils mixed therein. Water is then fed from the irrigation water supply pipe 5 to elute components of the slow-release fertilizer 9 in the frames 3 in the recessed form, irrigate the culture medium 2 and cultivate tomatoes.，下面是Fertilizer applicator专利的具体信息内容。
