The emergence rate of carrot seeds is high after soaking.

Carrot seeds are sown according to the conventional method because the epidermis is attached to a layer of spiny hairs, and the emergence is slow and irregular. After years of practice, the effect of soaking seeds with hydrogen peroxide solution is better, and it has been popularized and applied in the carrot production base of Xiangcheng County. Soak the seeds with 25% hydrogen peroxide solution in a container, pour into the carrot seeds that have been rubbed off the bristles, stir with sticks while pouring, soak for 30 minutes and 50 minutes. After the seeds were germinated and soaked, the seeds were removed from the hydrogen peroxide solution, then washed with clean water for 3 times and filtered at the same time, then filled in a container and covered with a wet cloth to accelerate germination. If the seeds are moderately mature and full, more than 85% of the seeds germinate in 7-8 days, and the seedlings can be completed 5 days after sowing. Note one is that before soaking the seeds, you should choose sunny days to dry the seeds. The second is to sterilize the seeds which have been soaked and germinated with chlorothalonil solution. Third, the seeds after seed soaking and accelerating germination and sterilization should be sowed in time and the soil should be moist. Fourth, cover 0.5-1cm thick soil after sowing and slightly suppress it, then cover the sun with mulch, and remove the mulch when 10%-15% of the seedlings are unearthed.
