  • Publication number: 20120211129
    Abstract: On at least one surface of a base metal plate (1) of an ?-? transforming Fe or Fe alloy, a metal layer (2) containing ferrite former is formed. Next, the base metal plate (1) and the metal layer (2) are heated to an A3 point of the Fe or the Fe alloy, whereby the ferrite former are diffused into the base metal plate (1) to form an alloy region (1b) in a ferrite phase in which an accumulation degree of {200} planes is 25% or more and an accumulation degree of {222} planes is 40% or less. Next, the base metal plate (1) is heated to a temperature higher than the A3 point of the Fe or the Fe alloy, whereby the accumulation degree of the {200} planes is increased and the accumulation degree of the {222} planes is decreased while the alloy region (11b) is maintained in the ferrite phase.

    Abstract: A subirrigation system 10 includes a water-impervious member 16, and keeps water content in soil of a cultivated land 200 in a proper state for growing a plant. The water-impervious member 16 is formed into an upper opening vessel shape, and has a water reserving function. Water is fed to an inner portion of the water-impervious member 16 from a water tank 12 via a feed water pipe 14, whereby a soil portion 26 in a gravitational water state is formed. A water level 28 of the gravitational water within the water-impervious member 16 is properly controlled to a desired water level by a water level controller 18 provided in the feed water pipe 14. The gravitational water within the water-impervious member 16 controlled to the desired water level is appropriately sucked up to the soil in an upper layer in accordance with a capillary phenomenon. Accordingly, a soil portion 30 in a capillary water state having proper water content is formed in the cultivated land 200.
