It should be noted that the material of the first cultivating member and the material of the second cultivating member may be the same or different, and the invention is not limited thereto.
Further, after planting the seedlings together with the first cultivation component to the second cultivation component S200, the method includes: s210, irrigating the first cultivation component with nutrient solution with a third EC target value so as to enable the root system of the seedling to grow to the second cultivation component, wherein the third EC target value ranges from 1.5 mS/cm to 2.0mS/cm.
As mentioned before, after the seedling has passed from the first growth assembly to the second growth assembly, the root of the seedling needs to grow towards the second growth assembly. In order to promote the development of the root system of the seedling, in the technical scheme provided by the invention, after the seedling and the first cultivation component are fixedly planted to the second cultivation component, the first cultivation component is irrigated by nutrient solution with a third EC target value, as the lower surface of the first cultivation component is communicated with the upper surface of the second cultivation component, the nutrient solution can enter the second cultivation component under the action of gravity, and as the root system of the crop is fertile towards water, the root system of the seedling can gradually grow into the second cultivation component. Further, in the technical scheme provided by the invention, the first cultivation component and the second cultivation component comprise coconut coir or rock wool, namely a soilless cultivation mode is adopted, and when seedling planting is carried out, the coconut coir needs to be soaked in clear water or a low EC nutrient solution before use. In the technical scheme provided by the invention, the first cultivation component and the second cultivation component both adopt coconut chaff, the vertical surface of the first cultivation component is wrapped by a light-tight plastic film, the upper surface and the lower surface are exposed, the volume of the second cultivation component is larger than that of the first cultivation component, and a plurality of cultivation positions are arranged on the second cultivation component and used for planting a plurality of first cultivation components, so that a plurality of seedlings can be planted simultaneously. It should be noted that the periphery of the second cultivation component is wrapped with a light-tight plastic film, and the upper surface of the second cultivation component is provided with holes with the area equal to that of the bottom surface of the first cultivation component, so as to form cultivation positions and enable the first cultivation component to be communicated with the second cultivation component. In addition, an interval film or an interval plate extending along the length direction of the second cultivation component is arranged in the second cultivation component, and the interval film or the interval plate and a plastic film around the second cultivation component form a whole so as to divide the second cultivation component into two cultivation areas which are not permeable to water; in order to facilitate drainage, a plurality of drainage holes are also formed in the bottom of the second cultivation component.
