Artificial salt pond system capable of accurately identifying salt tolerance of plants

Abstract

The invention discloses an artificial salt pond system capable of accurately identifying the salt tolerance of plants. The artificial salt pond system comprises an artificial salt pond; a plurality of salt tanks are arranged in the artificial salt pond; a salt-water proportioning device is arranged at one end of the artificial salt pond; water distribution pipes are arranged among the salt tanks; the water distribution pipes are connected in the corresponding salt tanks through sewer pipes; and one ends of the water distribution pipes are inserted into the artificial salt pond and are connected with a water outlet pipe through connecting water pipes. According to the artificial salt pond system capable of accurately identifying the salt tolerance of the plants, the sewer pipes are arranged in the salt tanks correspondingly and connected to the water distribution pipes, saline water stirred by a stirring barrel can be conveyed into the salt tanks, and the salt content in the salt tanks can be controlled by controlling the salt content of the saline water in the stirring barrel, and the stress of the salinized soil on the plant under the natural condition can be better simulated, so that the salt tolerance of the plant can be more objectively and accurately identified and evaluated.

Description

technical field [0001] The invention relates to the technical field of artificial salt ponds, in particular to an artificial salt pond system that can accurately identify the salt tolerance of plants. Background technique [0002] Different plants and different varieties of the same plant have different tolerances to salt ions. Selecting crop varieties with strong salt tolerance for planting in saline soil can not only improve the soil, obtain ecological benefits, but also obtain economic benefits, which is of great significance to ensuring national food security. [0003] At present, domestic and foreign research on crop salt tolerance mostly focuses on the seedling stage, and most of them use hydroponic screening with saline nutrient solution. However, for the same species, the salt tolerance mechanism is different in different growth and development stages, and the salt tolerance at the seedling stage cannot reflect the salt tolerance of the whole growth stage. In addit...

AI Technical Summary

Problems solved by technology

However, for the same species, the salt tolerance mechanism is different in different growth and development stages, and the salt tolerance at the seedling stage cannot reflect the salt tolerance of the whole growth stage.

In addition, the structural components of the soil are complex, and there is a certain gap between the identification results of the hydroponics method and the actual field conditions.

The existing salt ponds have many deficiencies, such as uneven distribution of salinity, poor sustainable utilization, difficult drainage and irrigation operations, and low efficiency. Therefore, we have improved this and proposed an artificial salt pond system that can accurately identify the salt tolerance of plants
