Abstract: PROBLEM TO BE SOLVED: To provide a cultivation method capable of enabling the cultivation by close planting of perennial field crops requiring the cultivation of a parent plant for a long period regardless of soil characteristics of a region and without diffusing injury by continuous cropping, and disease. SOLUTION: This method for cultivating perennial field crops is characterized in that the perennial field crops are separately transplanted in a divided vessel filled with coarse soil comprising volcanic pumice and having 1-5.6 mm particle diameter and porous surface. A culturing liquid is preferably fed by a drip gravity-feed irrigation method, and the perennial field crop is preferably pineapple. Preferably, the pH of the culturing liquid is regulated so as to be 4-8, and the divided vessel is arranged in a greenhouse. The divided vessel preferably has about 24 cm diameter and about 30 cm depth, is filled with about 7 liter pumice medium, and has a drainage hole in the side wall at the vicinity of the bottom.
