Description

Cultivation bed for tidal irrigation

Technical Field

The utility model relates to a plant cultivation field, especially a cultivation bed that morning and evening tides were irrigated.

Background

The tidal irrigation plant nutrient solution cultivation technology is a water-saving irrigation mode commonly used for water culture nutrient solution cultivation, is designed according to the tidal water fluctuation principle, allows potted plants or bed-planted plants to be indirectly irrigated by nutrient solution, and can effectively improve the irrigation efficiency of water resources and nutrient solution. The common tidal irrigation technical means is that water is pumped to the seedbed through a water pump or a water valve for time control, so that the water level in the whole seedbed slowly rises and reaches a proper liquid level height (called flood tide), and the cultivation bed is submerged to a depth of about 2-3 cm; after a certain time (full absorption of crop root system) is kept, after about 10-15 minutes, the nutrient solution rises to the surface of the medium in the pot due to capillary action, at the moment, a water return opening is opened, the nutrient solution is discharged and returns to a nutrient solution pool (called as falling tide), and the nutrient solution is sent out when another cultivation bed needs water. The key technical principle of tidal irrigation lies in the control of water level and the uniformity of water absorption saturation of plant root system media.

The current tidal irrigation cultivation device, when the cultivation bed was watered, can't guarantee that the equilibrium that whole liquid level plane water level rises reaches the purpose that each plant was absorbed water simultaneously on the water bed, when the cultivation bed was watered and is drained, the balanced decline of whole liquid level plane equally can not be guaranteed to current cultivation bed, and the local area after the current cultivation bed drainage has certain ponding often, probably leads to the plant root system looks water bed to grow.

In addition, the conventional tidal irrigation device is generally controlled by a water pump or a water valve, and when large-area seedbed cultivation or multilayer seedbed cultivation is carried out, the whole control system is more complicated due to the arrangement of the water pump or the water valve, so that the actual application of the tidal irrigation device is not facilitated.
