Experimental vitreous deep flow circulating hydroponic device

Abstract

The invention discloses an experimental vitreous deep flow circulating hydroponic device. An inclination, which has a lower front part and a higher rear part, is arranged at the top end of a rectangular vessel of the device; an inner side board is connected with the interior of the rectangular vessel; the rectangular vessel is divided into a purified water tank and a water supply tank by the inner side board; a water pump is arranged in the water supply tank; a sloping plate is arranged at the top end of the rectangular vessel; at least two layers of hydroponic pools are arranged in a stepped form on the sloping plate; a perforated fix planting plate is arranged at the top of each hydroponic pool; a water circulating pipe is arranged between the two adjacent hydroponic pools; the distance between the lowest part of a hole of the water circulating pipe and the lowest part of the bottom surface of the hydroponic pool is greater than 10 cm to ensure that the depth of nutrient solution in the hydroponic pool is greater than 10 cm; the hydroponic pool at the lowest part is connected with a water outlet pipe; the hydroponic pool at the highest part is connected with a water supply pipe; and the lower end of the water supply pipe is connected with the water pump. The device achieves the deep flow hydroponic purpose and forms a favorable deep flow circulating system, so as to be convenient to observe the root system growth of the plants and test the fertilizer efficiency, is low in cost, can meet the experimental requirement for deep flow hydroponic plants, and is convenient to use.

Description

technical field [0001] The invention relates to a plant hydroponic device. In particular, it relates to a deep liquid circulation hydroponics device. Background technique [0002] Plant hydroponics is a kind of soilless cultivation, and hydroponics includes deep liquid flow technology and nutrient liquid film technology. Because soilless cultivation can artificially create a good rhizosphere environment, it can effectively prevent soil continuous cropping diseases and physiological obstacles caused by soil salt accumulation, and fully meet the needs of crops for mineral nutrition, water and other environmental conditions. Workmanship, high yield and high quality. has received increasing attention. The deep liquid flow technology has the characteristics of a deep circulating nutrient solution layer, and it is not easy to change sharply in pH, water storage, etc., providing a relatively stable growth environment for plant roots and high production safety. [0003] The exis...
