Technical Field

[0001] The utility model relates to the technical field of soilless cultivation, in particular to a three-dimensional soilless cultivation experimental device. Background Art

[0002] Soilless cultivation is a new crop cultivation technology developed in recent decades. Crops are not cultivated in the soil, but in a water solution (nutrient solution) containing dissolved minerals, or in a certain cultivation matrix with nutrient solution for crop cultivation. As long as there are certain cultivation equipment and certain management measures, crops can grow normally and obtain high yields. The characteristic of soilless cultivation is to replace the soil environment with an artificially created crop root growth environment. It can not only meet the needs of crops for nutrients, water, air and other conditions, but also control and regulate these conditions to promote better growth of crops and obtain a better balance between nutritional growth and reproductive growth.

[0003] However, current soilless cultivation lacks standardized experimental equipment, and experiments are usually conducted in different containers, which makes it impossible to uniformly control environmental variables. During the experimental comparison process, soilless cultivation containers will also waste too much space resources, and the nutrient solution cannot be circulated, which can easily breed bacteria and cause plant diseases. Utility Model Content
