Technical field
The present invention relates to cultivation technique without soil field, especially a kind of soilless culture automatic water supply device that can keep water level balance.
Background technology
As everyone knows, soilless culture (soilless culture) refer to without natural soil with matrix or only nursery time matrix, after field planting, carry out the cultivation method of irrigating with nutrient solution.Can Economization on land due to soilless culture can the good rhizospheric environment of artificial creation to replace soil environment, effectively prevent soil continuous cropping disease and soil salt from accumulating the physiological disorder caused, fully meet crop to mineral nutrition, the needs of the environmental condition such as moisture, gas, the stock of cultivation can recycle again, therefore has water-saving, economizes the features such as fertilizer, saving of labor, high yield and high quality.
That delivers according to Hunan Province's atomic energy Applied Research Laboratory is entitled as " research of potato gold water level organic soilless cultivation technology ", and the known water level for soilless culture Different Crop is selected particularly important.
With the culture fluid of artificial preparation in soilless culture, the needs of supply plant and mineral nutrition.For making plant be erect, available quartz sand, vermiculite, peat, sawdust, plastics etc. as supporting dielectric, and can keep the ventilation of root system.Facts have proved for many years, the crops such as soybean, soya bean, Kidney bean, pea, wheat, paddy rice, oat, beet, potato, wild cabbage, leaf lettuce, tomato, cucumber, the output of soilless culture is all than the height of soil cultivation.
But soilless culture is all be placed in water planting environment by crop, makes crop root be in culture fluid always; Some crops do not need the too much water yield in vegetative period, if root immerses nutrient solution too much will cause the situation such as rotten.
Summary of the invention
The object of this invention is to provide a kind of soilless culture automatic water supply device that can keep water level balance.
Technical scheme of the present invention is: it comprises flowerpot, described flowerpot is without permeable hole flowerpot, is provided with the tube connector designed according to siphon principle between flowerpot and transparent supply tank, is provided with at least one plantation platform in flowerpot, plantation platform is placed with plantation flowerpot, and plantation flowerpot is double-decker; Described tube connector is between flowerpot and transparent supply tank, arrange infundibulate inverted siphon or air inlet pipe and outlet pipe; One end of described air inlet pipe is fixed on the casing upper surface of flowerpot top by 1/3 to flowerpot, and the other end is arranged on bottom transparent supply tank; One end of outlet pipe is arranged on the bottom of flowerpot, and the other end is fixed on bottom transparent supply tank.
Transparent supply tank is shaped with water injection hole.
Flowerpot and transparent supply tank hinged.
Described plantation platen is the gripper shoe with depression be erected in flowerpot.
One end outer wall that air inlet pipe is positioned at flowerpot is tangent with the inwall of the casing upper surface being positioned at flowerpot.
Described air inlet pipe and outlet pipe are flexible pipe.
The tube connector end of transparent supply tank is provided with solar water pump, and described solar water pump is made up of solar panels, photovoltaic converter, support and the motor with propeller type blades.
