The invention provides a cultivating carrier and a cultivating system. The cultivating carrier comprises a floating cultivating body, wherein the cultivating body comprises at least one cultivating hole, and further comprises at least one ventilating structure communicated with the cultivating hole; the ventilating structure can enable outside air to enter the cultivating hole; the cultivating hole comprises an upper part and a lower part; a plant enters from an opening in the upper part and is supported at the upper part; at least one part of the root system of the plant is positioned at the lower part. Through the cultivating carrier and the cultivating system, the outside air can enter the cultivating hole in the plant cultivating process, so that the root system of the plant contacts oxygen in the air to reduce a root rot condition in the plant cultivating process to enhance the quality of the plant, and further the production efficiency is improved.

Cultivating carrier and cultivating system

The invention relates to the technical field of agricultural facilities, in particular to a multifunctional soilless culture device and an application thereof. The device is mainly used for vegetable culture, and comprises a soilless culture tank, two end covers, and environment regulation and control equipment, wherein the soilless culture tank comprises a tank body and an upper cover, and the tank body comprises a base plate, a placing plate, a first side plate and a second side plate; the upper cover is provided with a plurality of fix planting holes; the placing plate is horizontally blocked between the first side plate and the second side plate, and an air current channel is provided a plurality of vent holes on side walls of the first side plate and the second side plate; and the two end covers are plugged at two ends of the soilless culture tank respectively, and are provided with a plurality of water holes and one air inlet respectively. The soilless culture device provided by the invention forms a relatively closed culture space, and a nutrient solution flows in the culture space to avoid pollution caused by external impurities; and the environment regulation and control equipment charges cold/hot air, an air fertilizer or ozone and the like into the air current channel, and conveys the gas to surroundings of plants uniformly through the vent holes, thereby achieving regulation of microenvironments.

Multifunctional soilless culture device and application thereof

The invention discloses a soilless culture nutrient solution phosphorus concentration online detection system and a detection method thereof. The system and the method realize online detection of the phosphorus concentration of a soilless culture nutrient solution. The system comprises a first sensor, a second sensor and a processing module, wherein the processing module is connected with the first sensor and the second sensor, the first sensor is used for acquiring the nitrogen ion concentration data of a nutrient solution to be detected and sending the nitrogen ion concentration data to the processing module, the second sensor is used for acquiring the volume data of the nutrient solution and sending the volume data to the processing module, and the processing module is used for determining the phosphorus concentration of the current nutrient solution based on the synchronous balanced nitrogen and phosphorus absorption of plants according to received nitrogen ion concentration data and the received volume data of the nutrient solution.
