Seed germination or seedling hydroponic device

Abstract

The invention relates to the technical field of crop culture, in particular to a seed germination or seedling hydroponic device. The device comprises a hydroponic plate and a hydroponic case, wherein the top of a case body of the hydroponic case is open, the hydroponic plate is located in the hydroponic case and floats on the surface of a solution in the hydroponic case, and a plurality of pores are formed in the hydroponic plate, so that roots can enter the solution in the hydroponic case through the pores after the seeds germinate. The hydroponic plate floats on the surface of the solution in the hydroponic case, the crop seeds can be partially contacted with the solution and partially contacted with the air, sufficient oxygen is supplied to the seeds while the seeds imbibe and absorb water fully, the hydroponic plate taken out is put in the hydroponic case accommodating a replaced culture solution, and replacement of the culture solution can be completed; the device can be used for batch seed germination and screening tests, realizes integration of germination and seedling culture, simplifies the intermediate process of sand culture and seedling transplanting, reduces damage to the seedlings and particularly the roots of the seedlings, and shortens the time for seedling recovery due to replacement of a culture medium.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a seed germination or seedling hydroponic device. Background technique [0002] At present, when studying the nutritional characteristics or stress resistance characteristics of crops such as wheat and corn, the commonly used test methods include hydroponics, pot planting and field experiments. Soil is the basic medium for plant growth. The results of pot and field experiments are more objective and reliable, especially the results of field experiments are closer to the actual situation. However, due to soil variability in space and time, it is difficult for pot and field experiments to control other conditions as accurately and efficiently as hydroponic experiments. The hydroponic culture test allows the root system of the crop to directly contact the nutrient solution containing the nutrient elements needed for the growth of the crop. It can quickly screen a large num...
