Water ploughing system for culturing vegetable and application thereof

Abstract

The invention discloses a water ploughing system for culturing vegetables and applicant thereof. The water ploughing system comprises a liquid storing system, a nutrient solution circulating system, a planting platform system and a protection system, wherein the liquid storing system mainly comprises a water reservoir, a liquid storing well and an oxygen increasing device; the water reservoir is connected with the liquid storing well by a pipeline; the liquid storing well is arranged under the earth surface; the elevation position of the water reservoir is higher than that of the liquid storing well; the oxygen increasing device comprises a return pipe and an air pressure pump; the nutrient solution circulating system mainly comprises a suction pump, a liquid feeding pipeline and a liquid returning pipeline; the planting platform system comprises a planting groove and a bedstead; the planting groove comprises a groove body and a groove cover; the groove cover and the groove body are movably connected; and the bottom of the groove body has the radian; the protection system mainly comprises a sunshade net, the minimum cover range of which is the planting platform system. The system overcomes the technical problem that the temperature of the nutrient solution in the traditional water ploughing culture is difficult to control, the dissolved oxygen is not enough and the production cost is overhigh; therefore, the system is suitable for the cultivation of various leaf vegetables and can realize the high-quality efficiency production of vegetables.

Description

technical field [0001] The invention particularly relates to a hydroponic system for cultivating vegetables and its application, belonging to the technical field of soilless cultivation. Background technique [0002] Soilless culture refers to a kind of planting technology that does not use natural soil, but uses nutrient solution containing various elements necessary for plant production and development to provide nutrition and enable plants to complete their life cycle normally. There are various forms of soilless cultivation, including substrate cultivation (SubstrateCulture), spray cultivation (Fog Culture), and hydroponic cultivation (Hydroponics). [0003] As an important form of soilless cultivation, hydroponics has been widely used in production practice, and has achieved great success and considerable economic benefits. [0004] Compared with traditional land farming (Land Farming) cultivation, hydroponic cultivation has the following advantages: [0005] (1) Outs...

AI Technical Summary

Problems solved by technology

[0014] The primary purpose of the present invention is to overcome the shortcomings and deficiencies of the existing hydroponic cultivation method, which have high production investment costs and cannot effectively control the nutrient solution circulation temperature and dissolved oxygen during the cultivation process, and provide a hydroponic system for cultivating vegetables
