Soilless capillary hydroponics rearing system

Abstract

The invention relates to a soilless cultivation system of capillary hydroponics, comprising a plurality of culturing grooves, a liquid storage tank, a liquid feeding pipe, a water pump, a flowmeter, a timer, a first backflow pipe, a second backflow pipe, a backflow tank, a pressure pump, a water filtering and disinfecting device, and a fertilizer blending tank. The tables for fixing and putting plants in the culturing grooves of the soilless cultivation system of capillary hydroponics are set fixedly, such that there is no damage to the roots of plants because of the liquid level changes of the nutrient solution and no worry about water or power cut because of the 5cm height of the nutrient solution. The invention adopts the root separating method to solve the conflict of oxygen uptake and liquid supplement with low consumption of energy. in addition, The bottom of the culturing groove can be provided with a culturing frame having the function of supporting to completely change the traditional stooping or squatting working way of the workers in the past, which is not only good for easy operation and management, but also for easy cleaning of the residue roots after harvesting. So the labor intensity can be reduced.

Description

technical field [0001] The invention belongs to the field of facility agriculture, in particular to a soilless hydroponic capillary cultivation system. Background technique [0002] Soilless cultivation technology is one of the most advanced and capital-intensive production methods widely used in protected agriculture in the world, and thus has become one of the main directions of research and development of protected horticulture in the world in the past century. Among them, soilless hydroponics cultivation technology is a newest cultivation method developed with the development of greenhouse production. More than 100 countries in the world have used soilless hydroponics technology for greenhouse production. More advanced countries include the Netherlands, Israel etc. At present, the commonly used soilless hydroponics cultivation system is mainly divided into the following three types: [0003] 1. The nutrient liquid film method (NFT) soilless hydroponics cultivation syst...

Problems solved by technology

Although this cultivation tank 11 can overcome the shortcoming of the cultivation tank 2 adopted by the nutrient liquid film method soilless hydroponic cultivation system, it has stable rhizosphere environmental conditions, small liquid temperature changes, sufficient rhizosphere oxygen supply, and will not be affected by Temporary power failure affects the supply of nutrient solution and other advantages, but its disadvantage is that because the foam board 14 is floating on the liquid surface of the nutrient solution 13, its position will change with the rise and fall of the nutrient solution 13 liquid level

Especially in the high temperature season in summer, the nutrient solution 13 is more affected by the temperature, so its evaporation rate is faster, and the plant 16 is hung or fixed on the foam board 14, so most of the plant root system stretches to the foam board 14 The surface of the nutrient solution 13 may be drilled into the non-woven fabric 12. At this time, when the liquid level of the nutrient solution 13 drops under the influence of high temperature, it is easy to cause strain on the root system of the plant, thereby affecting the normal growth of the plant.

In addition, as mentioned above, this kind of cultivation tank 11 is below the ground, so the staff need to bend over or squat to operate, which is not only labor-intensive, but also the remaining stub roots after harvesting are not easy to clean up.
