Solution feeding system for soilless culture and application

Abstract

The invention relates to a solution feeding system for soilless culture. The solution feeding system comprises a stock solution barrel, a liquid level regulation and control barrel and at least one matrix cultivation tank which are sequentially connected through a pipeline, wherein a water outlet of the stock solution barrel is located above a water inlet of the liquid level regulation and control barrel, so that the stock solution barrel can supply a solution to the liquid level regulation and control barrel through gravity; a liquid level sensor which is used for sensing liquid level altitude and controlling the solution supplying of the stock solution barrel is arranged in the liquid level regulation and control barrel; and the liquid level regulation and control barrel communicates with the matrix cultivation tanks. During use, solution feeding operation is automatically completed through gravity by using liquid level head drop without using a water pump and consuming electric power, and thus, the aims of environment-friendliness and energy saving can be achieved. Meanwhile, capillary tubes in porous mixed matrixes in the matrix tanks are used for adsorbing moisture so as to irrigate and moisten the matrixes, and thus, automatic solution feeding and automatic regulation and control on the moisture content of the matrixes in the cultivation tanks are completed.

Description

technical field [0001] The invention relates to the field of devices for soilless cultivation, in particular to a liquid supply system for soilless cultivation. Background technique [0002] Soilless cultivation can produce vegetables on non-arable lands such as saline-alkali land, Gobi, and deserts that cannot be used by traditional agriculture, and soilless cultivation is also an effective method to solve the obstacles of continuous cropping of facility vegetables. Therefore, the development of soilless cultivation technology is an important way to achieve high yield, high quality and high efficiency of vegetables, and it is also a new cultivation method for vegetable production to transform from traditional agricultural production to modernization, scale and intensification. Establishing a soilless cultivation technology system that is suitable for my country's national conditions, is environmentally friendly, and is easy to operate can not only achieve high-quality and e...

Problems solved by technology

[0005] Aiming at the defect of high cost in existing soilless cultivation facilities, the supply and discharge of nutrient solution are mostly realized by water pumps, the present invention provides a solution for soilless cultivation that does not require electricity and utilizes gravity to supply the solution. System; at the same time, the capillary of the mixed substrate in the substrate tank is used to absorb water to irrigate the wet substrate to replace the drip irrigation end such as the drip arrow, so as to avoid the blockage of the drip arrow, which will cause uneven irrigation and further affect the yield.
