Soilless culture system

Abstract

The invention discloses a novel soilless culture system which belongs to the field of soilless culture. An outlet of a nutrient solution pool (1) in the system is connected with a liquid inlet of a liquid containing tank (6) via a water pump (3), and a liquid outlet end of the liquid containing tank (6) is connected with an inlet of the nutrient solution pool (1) via a liquid return main pipe (9); two or more liquid containing tanks are connected in parallel, a culture pot or culture bag is arranged in the liquid containing tank (6), and a disinfection device (11) and the nutrient solution pool (1) form a loop for disinfecting nutrient solution independently; and the liquid outlet ends of the liquid containing tanks (6) have two structures both of which can meet the requirement of tide-type irrigation. The system can realize the tide-type irrigation and the enclosed recycling use of the nutrient solution simultaneously, is suitable for the soilless culture of crops such as vegetables, flowers and the like, and has the advantages of simple technology and equipment, low cost, stable and reliable operation and the like.

Description

technical field [0001] The invention relates to a soilless cultivation system, in particular to a kind of comprehensively utilizing the characteristics of tidal irrigation and closed cultivation system, which adopts the substrate cultivation system of trough + basin or trough + bag. Background technique [0002] In the process of rapid development of modern facility agriculture, the planting method of soilless cultivation is more and more widely used. At present, protected cultivation in the United States, Japan and other countries basically popularizes soilless cultivation technology; the European Union also clearly stipulates that in the 21st century, all horticultural crops in EU countries must realize soilless cultivation. [0003] Closed soilless cultivation is to collect, purify, sterilize, detect, and adjust the excess water and fertilizer that seep from the roots of plants after watering, and then reuse them for irrigating crops; it can not only improve the utilizati...

AI Technical Summary

Problems solved by technology

[0005] Although nutrient solution cultivation in soilless culture can make plants grow faster, nutrient solution cultivation has not been widely applied in production due to the difficulty of management, the difficulty in solving the contradiction between water and air, and poor buffering capacity.

Substrate cultivation is still the mainstream of soilless cultivation at present, among which trough type, bag type and pot type are the main cultivation methods, and drip irrigation and surface flood irrigation are the main irrigation methods; Cultivation), unable to realize root irrigation, low water and fertilizer utilization rate, serious environmental pollution (secondary salinization), and many other shortcomings. At present, there is no matrix cultivation system that can overcome the above shortcomings at the same time.
