When salt water is selected, it is necessary to grasp the concentration of salt water. It is best to use a pycnometer to measure the concentration. If no pycnometer is available, dissolve the dissolved brine in a bowl and put in a spoonful of seeds to be selected. If it sinks, it indicates that the salt water is too light and you should continue to add salt; if most of the seeds are floating on the water, The brine is too concentrated and should be diluted with water until most of the seed is inclined to the bottom of the bowl. In addition, it should be noted that when salt water is continuously used many times, salt will be taken away by the seeds, and salt should be added in time to prevent the decrease of the concentration and affect the quality of seed selection.

Saline seed selection concentration
Salt water selection has the following advantages: Because the specific gravity of the seed and the specific gravity of the same volume of salt water are different, when the seeds are poured into the appropriate concentration of salt water, the seeds with fullness and completeness are sinking; the unqualified seeds such as pods and broken grains, etc. Because of its small specific gravity, it will float on the surface of the water and select excellent seeds.
