专利汇可以提供Irrigation, fertilization and ventilation to the rhizosphere of cultivated plants, device therefor and feeder for irrigation and fertilization专利检索，专利查询，专利分析的服务。并且PURPOSE:To conduct irrigation and fertilization, as the water content is maintained uniform in the cultivation medium, by setting the water level with capillary force and siphonage of strings with capillary structure and by water level adjustment and utilizing a water feeder for maintaining a certain water level. CONSTITUTION:Water or a cultivation solution from the source of water supply or a water tank is set to a certain level by adjusting it by means of a water feeder so that the water or solution is distributed to the irrigation pipe lines as the water level is maintained constant. The water within the level is connected to the upper part of the cultivation medium with a water path of a reversed J-shaped pipe which is filled with a string having a capillary structure and the string is immersed in the water at one end, while the other is buried from the upper part of the medium into the rhizospheric zone to form the siphoned water path. Thus, irrigation and fertilization are conducted, as the water content is kept uniform in the medium and, when needed, the rates of irrigation and fertilization are freely controlled.，下面是Irrigation, fertilization and ventilation to the rhizosphere of cultivated plants, device therefor and feeder for irrigation and fertilization专利的具体信息内容。
