SOLUTION: A means 6 for feeding liquids from liquid containers 1 little by little is formed. Concretely, an air controlling port 4 is formed at the upper part of a liquid container 1, the amount of supply of water or a liquid fertilizer is controlled by using the air controlling port 4, and an osmotic liquid supplying tube 6 using osmotic pressure is attached at the lower part of the container 1. The osmotic liquid supplying tube 6 is preferably formed by inserting an absorbing and discharging core body for absorbing and discharging liquid into an elastic hollow tube having air holes. Examples of the absorbing and discharging core body include a bar-shaped body formed from plant fibers or the like. Several pieces of the osmotic liquid supply tubes 6 are, if necessary, connected via joints 7, 8 or the like, and branched, and each of the branch is buried into soil via an insertion fitting 9.

[0017]

The present invention is embodied in the form described above and has the following effects.

By providing an osmotic liquid supply pipe using osmotic pressure in the liquid container, the osmotic liquid supply device can supply a small amount of water and liquid fertilizer stably over a long period of time, and does not use a motor or the like. Therefore, when the supply of water and liquid fertilizer is absent for a long period of time, it is safe and energy-saving.

Further, by providing a lid at the water supply port of the liquid container, the evaporation of water and liquid fertilizer in the container is prevented, and by providing an air adjusting port in the liquid container, the supply amount can be easily adjusted.

Further, since the permeated liquid supply device utilizes permeation, since the water pressure is high in the pipe, even if an air hole is provided, there is no fear of water leakage and the air generated in the pipe can be diffused, so that the supply efficiency can be improved. In addition, water and liquid fertilizer can be prevented from being oxidized, and because the water pressure is not high, the connection by the joint is easy, and by increasing the number of branches, water and liquid fertilizer can be supplied to many places at once.

In addition, since the permeated liquid supply device can supply water at a position distant from the supply point, there is no need to pour water on passers-by when passing water on a veranda or the like.

Further, the permeated liquid supply pipe can be easily manufactured simply by inserting a substance that absorbs and diffuses a liquid into a hollow tubular substance having elasticity such as rubber, so that it can be produced at low cost.

Further, since the permeated liquid supply pipe takes up little space and can be arranged freely, it can be installed indoors and outdoors.
