Drying seeds: In order to improve the water absorption of seeds, it is necessary to choose sunny days to soak the wheat seeds for 2-3 days before soaking, and clean up the impurities and pods in the seeds to ensure the purity and quality of the seeds.
Selection of biogas slurry: As a biogas digester for biogas slurry soaking, it must be used normally for more than one month. The biogas slurry of spent pond and dead pool cannot be soaked. A few days before soaking, the water pressure cover was opened, exposed to the air for several days, and stirred several times to disperse a small amount of hydrogen sulfide gas, and to remove the scum on the water surface. If the concentration is too high, add 1-3 times of water before soaking.
Bag soaking: Select a water-permeable cloth bag or a plastic woven bag to load wheat seeds. Be careful not to overfill, preferably around two-thirds of the bag, to prevent the seeds from swelling and bursting the bag, and then tighten the bag. A wooden stick was placed across the pressure chamber of the digester and a string was tied to suspend the seed bag so that the seed was completely immersed in the biogas slurry. Soaking time is generally about 12 hours, soaking time should not be too long, otherwise it will affect the bud.
Cleaning sowing: After the soaking of the biogas slurry, remove the seed bag, wash it with clean water, and let the water in the bag leak. Then spread the seeds on the mat and allow the seed surface to dry after soaking. If germination is required, germination can be performed.
