Fig. 1 is a cross-sectional view of the present invention.
Specific embodiment
One embodiment of the present of invention, with reference to Fig. 1, comprise and hold soil container 6 and water storage container 7, hold soil container 6 and water storage container 7 and be respectively the upper and lower of same container, two-layerly separate by a dividing plate 5, half of dividing plate 5 be bending upwards, form a folding line 50 at dividing plate 5 middle parts, other is provided with a lever 1, its fulcrum 10 is fixed in folding line 50 places of dividing plate 5 lower surfaces, and first end 11 of lever 1 links to each other with soil 60 in holding soil container 6 by a water-suction rope 2, and second end 12 is fixed with an absorbent material 4, absorbent material 4 links to each other with soil 60 in holding soil container 6 by another water-suction rope 3, and second end 12 of lever 1 is positioned at upwards one side of bending of dividing plate 5.Dividing plate 5 is provided with aperture 51, and water-suction rope 2 and water-suction rope 3 pass from aperture 51.Absorbent material 4 adopts and places soil 60 in the shelly body, water-suction rope 2 and water-suction rope 3 adopt knitting wool, cotton thread or glass spinning line as material, water-suction rope 2 and the soil 60 that holds in the soil container 6 have a plurality of contact points 21, and water storage container 7 is connected with water inlet pipe 8, and water inlet pipe 8 is provided with altitude valve 9.
Soil begins suction from drying regime, along with the increase of moisture in the soil, and several forms such as its form process hygroscopic water, membranaceous water, capillary water, gravitational water, the water-holding capacity that reaches capacity at last, wherein, soil is about 8 * 10 to the suction of capillary water
3-6.25 * 10
5Pa, capillary water can move up and down in soil, and the effect that dissolves nutrients in addition and carry nutrient simultaneously is so capillary water is the most effective moisture form in the soil.
Feedwater process of the present invention is: preestablish lever 1 first end 11 weight greater than the weight of second end 12 and absorbent material 4 drying regimes and, therefore first end 11 enters 70 li in water downwards, be in than drying regime owing to soil 60 this moment, it is mobile in soil 60 that its water absorbing force impels moisture to pass through water-suction rope 2, moisture in the soil 60 constantly increases, when its moisture form reached the most effective moisture form and is the capillary water form, the confining force of 60 pairs of moisture of soil descended greatly.
When said process takes place, the water absorbing force of absorbent material 4 impels moisture to move to absorbent material 4 by water-suction rope 3 from soil 60, its water content remains consistent with the water content of soil 60, when the moisture form in the soil 60 reaches the capillary water form, the weight of second end 12 of absorbent material 4 and lever 1 and greater than the weight of lever 1 first end 11, therefore lever 1 first end 11 is upturned and leaves the water surface, stops soil 60 is supplied water.
After this, because plant is to the absorption of moisture in the soil 60, moisture in the soil 60 constantly reduces, moisture on the absorbent material 4 also constantly moves in soil 60 simultaneously, when the moisture in the soil 60 is lower than effective status again and is the capillary water state, the weight of second end 12 of absorbent material 4 and lever 1 and less than the weight of lever 1 first end 11, first end 11 of lever 1 enters the water surface downwards, begins again to supply water to soil 60.
Said process makes the moisture in the soil 60 maintain the such poised state of plant requirement all the time because the effect of lever 1 constantly repeats automatically, and can correspondingly absorb moisture from water storage container 7 to moisture suction amount difference according to the different times plant.
The present invention realizes focuses on controlling the height of the water surface in the poised state of lever 1 and the water storage container 7, the poised state of control lever 1 can realize that the height of the water surface is then realized by the altitude valve on the water inlet pipe 89 in the control water storage container 7 by the thickness of control absorbent material 4.Terrestrial plant is divided into humidogene, middle life, drought is given birth to three kinds, for hygrophyte, need make the moisture in the soil 60 remain on a higher state, therefore can correspondingly reduce the thickness of absorbent material 4, be in time in the water with first end 11 that increases lever 1, promptly increase water supply time; In like manner, for xerophytes, then need the thickness of corresponding increasing absorbent material 4.
The present invention is not limited to adopt the form of basin, also can be widely used in the water supply of various terrestrial plant roots such as green house.
