Machine. The following describes the pre-sow seed processing method:
1. Selection of salt water and warm soaking Seeds are selected with 1:10 saline solution to remove some of the bacteria-bearing seeds and seedlings, and then treated in water at 55 °C ~ 60 °C for 10 minutes to kill the pathogens on the seed coat surface. Soaked in cold water, dried and sown.
2. The selection of ammonium sulfate water is carried out by using 10% to 15% ammonium sulfate water. After seeding, it can be sown after washing with water and drying.
