Description
Technical Field
The invention relates to the technical field of experimental seedling raising, in particular to a seedling raising tray for toxicological experiments.
Background
Plant toxicology experiments are an important part of ecological toxicology, and the experiments observe the change of plants by exposing the plants to water and soil environments containing pollutants with different concentrations, and analyze the mechanism of the influence of the pollutants on the plants. Most toxicology experiments are acute toxicity experiments, and the germination rate of seeds and the root morphology of seedlings are selected as common effect terminals. Thus, the completion of the cultivation of seeds and seedlings is the basic work of the experiment. In experiments, an experimental device for breeding and raising seedlings is indispensable. The seedling tray in the prior art is not specially used for plant toxicology experiments, and in order to ensure air permeability, the bottom of the common seedling tray is provided with a drain hole, but in the toxicology experiments, sewage-containing irrigation water can be discharged from the drain hole, so that experimental conditions of other treatment groups can be influenced, and the toxicology experiments fail. If the drain hole is sealed, the water is accumulated at the bottom of the seedling raising tray after watering, so that the respiration of the plant root system is blocked, and the growth of plants is affected. In addition, most experiments need to observe the growth condition of the root system, and main observation indexes are the growth length, the overall shape and the like of the root system. Therefore, the integrity of the plant root system needs to be ensured during the test sample receiving. However, due to the difference of soil media, the root system of the seedling is usually coiled in staggered joint, and a large block of cohesive soil is adhered to the root system, so that the shape of the root system is difficult to be ensured to be complete in the process of taking out the plant soil lump tightly adhered to an experimental apparatus.
Therefore, there is a need for a tray for toxicological experiments to solve the above problems.
