摘要: 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.
摘要翻译: 子灌溉系统10包括不透水构件16,并且在适当的状态下将耕地200的土壤中的含水量保持在植物生长中。 防水构件16形成为上开口容器形状,并具有储水功能。 水通过给水管14从水箱12供给到不透水构件16的内部,由此形成重力水状态的土壤部分26。 不透水构件16内的重力水的水位28被设置在给水管14中的水位控制器18适当地控制到期望的水位。防水构件16内的重力控制到 根据毛细管现象,期望的水位被适当吸入上层的土壤。 因此,在耕地200中形成具有适当含水量的毛细水分状态的土壤部分30。
