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 a 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 matures moderately and satisfactorily, more than 85% of the seeds normally germinate in 7-8 days, and the seedlings can be established 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 it, and then use the cover to shade, and remove the covering when 10%~15% of the seedlings are unearthed.
