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 years of practice, soaking seeds with hydrogen peroxide solution before sowing can effectively increase the germination rate of carrot seeds.
Soaking time: Prepare a 25% solution of hydrogen peroxide in a container, pour in 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.
The first thing to note is that before soaking, the sun should be selected for sunny days. 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 suppress a little, and then cover the shade, until 10% to 15% of the seedlings uncovered when the soil is uncovered.
