Soilless culture device with liquid levels capable of being adjusted

Abstract

The invention relates to the field of plant culture devices, in particular to a soilless culture device with liquid levels capable of being adjusted. The soilless culture device with the liquid levelscapable of being adjusted comprises culture bed bodies, liquid supply devices and liquid discharge devices; and each culture bed body is in a concave shape as a whole, liquid-pouring grooves are formed in the bottoms of the culture bed bodies, both ends of the bottom of each culture bed body are provided with concave-shaped sedimentation tanks, liquid overflow openings and liquid outlets are formed in the culture bed bodies, the levels of the liquid overflow openings are higher than those of the liquid outlets, the liquid supply devices and the liquid discharge devices are placed in the culture bed bodies, water flow adjusting holes are formed in the liquid supply devices, liquid level adjusting holes / seams are formed in the liquid discharge devices, and through a synergistic effect of the liquid supply devices and the liquid discharge devices, the flow uniformity of liquid in culture beds is improved. The soilless culture device with the liquid levels capable of being adjusted is simple in structure, reasonable, simple and convenient to operate and wide in application range, the problem of uneven water quantities in the culture beds is solved, the flowing uniformity of the liquidin the culture beds is effectively improved, elimination of sediment of waste dregs is facilitated, and blocking of the liquid outlets is avoided.

Description

technical field [0001] The invention relates to the field of plant cultivation devices, in particular to a soilless cultivation device with adjustable liquid level. Background technique [0002] Soilless cultivation refers to a plant cultivation technique that uses nutrient solution or solid substrate to add nutrient solution without using natural soil. At present, matrix culture and hydroponics are the two main forms of soilless culture. Hydroponics can be divided into deep liquid flow method and nutrient liquid film method according to the depth of nutrient solution. Plants have short root systems at the seedling stage and are not suitable for cultivation in hydroponic devices with low liquid levels, while some crops have more developed root systems. , Cultivation in a hydroponic device with a high liquid level may cause the nutrient solution to overflow, so different growth stages and different types of plants require different height liquid levels. Substrate cultivatio...

AI Technical Summary

Problems solved by technology

For example: a fixed-size water outlet is set at the water outlet, and the liquid level height in the bed is completely adjusted through the flow rate of the soilless cultivation device. The operation is difficult, the adjustment is cumbersome, and the effect is poor. For example, the shallow liquid flow of the tubular cultivation bed or the deep liquid flow cultivation technology is used in the greenhouse to cultivate leafy vegetables; the substrate cultivation tidal irrigation cultivation bed adopts a certain height of baffle or water plug Realize the liquid level control in the cultivation bed

The liquid level of the device is fixed, and after the liquid supply is completed, the baffle or water plug needs to be pulled out to drain the liquid, and the operation is cumbersome; the hydroponic planting device with the liquid level adjustment function, this type of patent is to set the water outlet height adjustable device, If the water outlet is connected to the "L" type water outlet, the height of the water outlet can be adjusted by rotating the "L" water outlet through the spiral structure 180°, and the liquid level in the cultivation bed can be adjusted.
