Soilless capillary hydroponics rearing groove

Abstract

The invention relates to a soilless cultivation groove of capillary hydroponics, comprising a groove body, a seepage prevention film, a table for fixing plant, a hydrophilic non-woven fabric, and a groove cover. The table for fixing and putting plants in the culturing groove of the soilless cultivation system of capillary hydroponics is set fixedly, such that there is no damage to the roots of plants because the liquid level of the nutrient solution is changed by the influence of external temperature and no worry about water or power cut because of the 5cm height of the nutrient solution. Theinvention adopts the root separating method to solve the conflict of oxygen uptake and liquid supplement in the way of making one part of roots on the surface of the non-woven cloth to adsorb oxygen in air and the other part in nutrient fluid to adsorb nutrition and water. 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 tank. 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 technology is a newest cultivation method developed along with the development of greenhouse production, which usually utilizes a cultivation tank with nutrient solution flowing inside to cultivate plants. Since the nutrient solution has or even exceeds the various nutrients supplied by the soil, and the root system does not contact the soil, various soil-borne diseases can be avoided, so it is more conducive to the growth and development of various plants. At present, the cultivatio...

Problems solved by technology

Although this cultivation tank 11 can overcome the shortcomings of the cultivation tank 2 adopted by the nutrient liquid film method soilless hydroponic system, it has stable rhizosphere environmental conditions, small liquid temperature changes, sufficient rhizosphere oxygen supply, and will not be affected by temporary Power outage affects the advantages such as the supply of nutrient solution, 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.
