METHOD FOR ELIMINATING BACTERIUM, NEMATODE, AND GROWTH INHIBITORY COMPONENT OF CULTIVATION FLOOR AND THE CULTIVATION FLOOR

摘要

PPROBLEM TO BE SOLVED: To provide a method for effectively decreasing bacteria or nematodes propagating in arable soil of a cultivation floor and further a growth inhibitory component, such as excessive fertilizer and salt, to provide the culture floor capable of being used in the method, and to provide a method for cultivating field crops and lowland crops utilizing the cultivation floor. PSOLUTION: This method for eliminating the bacteria, the nematodes, and the growth inhibitory component of the cultivation floor comprises using the cultivation floor which receives the arable soil inside a tank thereof composed of a water-impermeable bottom part and a water-impermeable frame body and makes it possible to conduct filling the arable soil with water and drainage of the water from the arable soil, wherein the cultivation floor is filled with the water for a fixed period and then dried by conducting the drainage of the water from the arable soil. The cultivation floor is preferably structured so that slopes are formed on the bottom part and a corner part of the frame body or a part of the frame body on a bottom side becoming low is made to be left open, for the purpose of improving the drainage from the arable soil.
