How to deal with asparagus seeds before planting?

How to deal with asparagus seeds before planting? What should be paid attention to when dealing with seeds? Ask the netizens who have planted to introduce asparagus planting, whether it is direct seeding cultivation or seedling transplanting cultivation, strict seed treatment must be carried out before sowing. The planting net has sorted out the treatment methods before sowing asparagus seeds, which are listed below for netizens' reference. Asparagus seed treatment method: first, soak the dry seeds in hot water at 55-58 degrees Celsius to kill the germs inside and outside the seeds. When soaking the seeds, it is required that after the seeds are put into hot water, the water temperature should be kept at 54-56 degrees Celsius for 20 minutes, and the seeds should be stirred regularly. When the temperature drops to 54 degrees Celsius, the heat should be increased from more than 70 degrees Celsius to 56 degrees Celsius. After soaking for 20 minutes, immediately pour out hot water, add cold water of about 25 degrees Celsius to cool, then scrub the seeds by hand for 10-15 seconds, and then soak the seeds in clean water. The amount of water soaked in asparagus seeds should be more than 5 cm higher than that of asparagus seeds, and the water should be changed once every morning and evening. Each time you change the water, you should scrub the seeds with your hands and scrub off the sticky material on the surface of the seeds. The strength of scrubbing is lighter and lighter each time. Soak at 20-25 degrees Celsius for 72 hours, drain, place in a clean basin or plate, cover with wet cloth, germinate at 25-28 degrees Celsius for 24 hours, and sow seeds. At this time, it can be seen that a small number of seeds have broken their breasts and exposed white. It has been reported that it will germinate for 48 hours or more and wait for the seeds to grow into radicles before sowing. This is easy to damage the radicle in practice. The reason for the treatment of asparagus seeds: as long as the soaking time is sufficient and the water temperature is kept at 20-25 degrees Celsius, seedlings can begin to emerge about 10 days after sowing after soaking for 3 days. Some people worry that soaking seeds in hot water at 55 degrees Celsius will affect seed germination. the results of comparative experiments show that seeds treated with hot water at 55 degrees Celsius for 20 minutes can improve the germination rate and germination energy of seeds, and effectively kill the germs carried by seeds. it is an effective measure to prevent stem blight transmitted by seeds. Matters needing attention when dealing with asparagus seeds: first, the water temperature of soaking treatment must be accurately grasped, and the thermometer measurement method should not be replaced by the extensive method of three-to-one cooling. The water temperature before the seed input is required to reach 57-58 degrees Celsius. After the seed is put in, it can be reduced to about 55 degrees Celsius. Note 2. Soak at 54-56 degrees Celsius for no less than 20 minutes. Third, after the soaking treatment, immediately pour hot water into the cold water to cool down. If the seed cannot be soaked in warm soup without a thermometer or without relevant conditions, soak the seed in cold water for 48 hours and then soak it in 50% carbendazim solution of 500 times of 1 Groud for 24 hours. The solution must be 2-3 cm higher than the seed. After soaking, drain the solution and sow the seed. In order to prevent the seeds from sticking to their fingers and sticking to each other due to moisture during sowing, a little dry fine soil or coal ash can be used to remove surface moisture and disperse the seeds.
