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 many years of practice, soaking seeds with hydrogen peroxide solution is better, and it has been popularized and applied in the carrot production base in Luancheng County.
Soaking time The prepared 25% hydrogen peroxide solution is filled in a container, poured into carrot seeds that are rubbed off the bristles, and mixed with a wooden stick for 30 to 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.
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 slightly suppress it, and then use the cover to shade, and remove the covering when 10%~15% of the seedlings are unearthed.
