Abstract

The invention discloses a high-efficiency soilless culture device for greenhouse agriculture. The high-efficiency soilless culture device for greenhouse agriculture comprises a soilless culture main body pipe, wherein multiple culture bins are embedded onto the soilless culture main body pipe at equal intervals and are communicated with the inner part of the soilless culture main body pipe; culture brackets are connected to the top parts of the culture bins; multiple first fixed pipe sleeves are sleeved on the soilless culture main body pipe at equal intervals. According to the high-efficiencysoilless culture device for greenhouse agriculture provided by the invention, a nutrient solution supplement pipe is arranged and separated from the soilless culture main body pipe, and when a nutrient solution is added, a connecting branch pipe on the nutrient solution supplement pipe is matched with a nutrient solution adding head so as to directly add the nutrient solution into the culture bins, so that the nutrient solution is added uniformly, and plants can be cultured efficiently; meanwhile, a propeller blade is arranged on the nutrient solution adding head, and a water flow can drive the propeller blade to rotate when the water flow is too large, so that the impact force of the water flow is reduced, and root systems of the plants are protected.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation devices, in particular to an efficient soilless cultivation device for greenhouse agriculture. Background technique [0002] Soilless cultivation is a new technology of crop cultivation developed in recent decades. Crops are not cultivated in the soil, but are planted in an aqueous solution (nutrient solution) with dissolved minerals, or in some kind of cultivation substrate, and the nutrient solution is used for crop cultivation. As long as there are certain cultivation equipment and certain management measures, crops can grow normally and achieve high yields. Because it does not use natural soil, but uses nutrient solution to irrigate crops, it is called soilless cultivation. The characteristic of soilless cultivation is to replace the soil environment with the artificially created crop root growth environment. It can not only meet the needs of crops for nutrients and water. , air...
