Soaking in warm water and soaking in warm water is soaking seeds in warm water of 55°C to 60°C for about 15 minutes. Seeds of wax gourd, eggplant and pepper are thick and hard. When soaking, the water temperature should be slightly higher. The time can be slightly longer. When soaking with warm water, it must be constantly stirred. Hot water boiled seeds with a pot of seeds, and then take a pot of the same size spare, first quickly pour the water into the pot with the seeds, then pour the water and seeds into the empty pot, so that it is repeated several times, 10 After a few minutes, cool the seeds with cold water. The soaking of copper sulfate solution with copper sulfate solution can prevent and cure hot pepper anthrax. Soak the pepper seeds in cold water for 6 to 8 hours, and then soak them in 100 times copper sulfate solution for 5 minutes. After soaking, wash the seeds and germination. Formalin solution soaking with formalin soaking seeds can prevent damping-off, eggplant brown leaf disease, tomato ringworm disease. The seeds were first soaked in 100-fold formalin for 15 minutes, removed and wrapped in wet gauze, and washed after two hours. The soaking of potassium permanganate solution with potassium permanganate solution can prevent tomato mosaic virus disease. Before sowing, the tomato seeds were soaked in a solution of 100 times potassium permanganate for 30 minutes, and the seeds were washed or sowed after washing. Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
