Carrot seeds adhere to a layer of bristles due to the epidermis, so they are sown by conventional methods, and the emergence is slow and irregular. After practice, soaking seeds with hydrogen peroxide solution is better.
Soaking time: Put the prepared 25% hydrogen peroxide solution in the container, pour the carrot seeds that are rubbed off the bristles, stir it with a wooden stick and soak for 30-50 minutes.
Seed germination after soaking seeds will be removed from the hydrogen peroxide solution, then rinse with water 3 to 4 times, while flushing filter water, filtered water Sheng Sheng in the container covered with a damp cloth primed. If the seed is mature and full, there will be more than 85% of the seed germination in 7-8 days, and the seedling will be 5 days after sowing. Note: First, soaking seeds, sunny days should be selected for drying. The second is to use chlorothalonil solution to sterilize seed that has been soaked with germination. Third, seed soaked after germination sterilization should be sown in time, requiring soil moisture. The fourth is to cover 0.5 to 1 cm thick soil after sowing and slightly suppress, and then cover the shade, until 10% to 15% of the seedlings uncovered when the soil is uncovered.
Cooling Agent, is a general term for all the chemicals that can produce cooling effects and are not strong. The most common Cooling Agent is menthol (especially L-menthol), but it should not be used in large quantities due to its strong odor and strong irritation to the skin, mucous tissue, and eyes. Therefore, many scientists have synthesized and extracted a new generation of cooling agent.
