Give seeds "bathing"
The "bathing" of the seeds is mainly for the purpose of sterilization and preferred seeds. There are four ways to do this. "Clean water bath" can use cold water, can also use 30 degrees warm water, the seeds slowly into the water, the seeds of sturdy seeds sink, and seeds, seeds and other seeds are floating in the water. Only need to remove scum to achieve the purpose of selection. The "brine bath" has a relatively small proportion of fresh water, and sometimes it is difficult to quickly identify the quality of the seeds. If you add different proportions of salt in the water, increase the proportion of the selected liquid, not only can rapidly emerge the inferior species, but also play a role in disinfection of the seed. Sometimes adding a little yellow mud in the water can also increase the proportion of selected liquid. The "hormone solution" is soaked with booster, paclobutrazol, chlormequat, etc., and can be fattened. "Pharmaceutical bath" in the water mixed with different drugs, such as dioxin, triadimefon, the brake effect on the seeds better. It can also put "chemical armor" on the seeds to prevent "winding" of pests and diseases.
