Soilless culture device and soilless culture method suitable for Orobanche coerulescens parasitic tomato

The invention discloses a soilless culture device and a soilless culture method suitable for Orobanche cucumeroides parasitic tomatoes. The matrix containers of all the soilless culture units are connected to the same medium circulation pipeline in parallel, and a U-shaped flow channel structure is formed between any two adjacent matrix containers, so that a U-shaped pipe pressure difference principle can be utilized; each matrix container is filled with the liquid growth matrix one by one continuously and equivalently on the basis of the pressure difference generated when the matrix in the medium circulation pipeline flows in the pipeline, the liquid growth matrix entering the matrix containers can be diffused into the plant growth containers through the through holes formed in the plant growth containers, and the plant growth containers are filled with the liquid growth matrix continuously and equivalently. The root systems of the tomato and the Orobanche cucumeroides are fully and uniformly contacted with
