Consultation: The farmers of Guazhou forage grasses inquired that the seedlings are now sown. How would the expert seed before sowing be treated? It would increase the germination rate, disease resistance, and emergence and neatness.
Answer: Selecting and drying seeds before sowing by the following methods can increase the germination rate, disease resistance and uniformity of emergence.
1. Breaking the dormancy period of hard seeds
(1) Rub the seed coat: Can be rolled on the stone grind, can also be mixed with the same amount of sand as the seed, spread on the cement floor and rubbed. The seed and equal amount of sand can also be placed in a woven bag, leaving a certain space for sealing, and then being beaten with a wooden stick.

(5) Inoculation of bacteria: This method uses the inoculation of Penicillium, Aspergillus oryzae, or Trichoderma viride, or a combination of the above species to treat alfalfa seeds, which can increase the germination rate and emergence rate of the seeds. The microbial mould used can be made苜蓿 Seed coating agent or seed dressing inoculant.
2. Disinfection and germination
(1) soaking with 1:10 saline, or 1% lime water for 5 minutes, remove the sunning for 2-3 days. (2) soak the seeds in warm water at 40°C for 10-12 hours, then remove the germination under the conditions of 20°C-25°C, wait until the seeds are white, and place them in a cool and dry place to dry for 6 hours.
