To plant autumn buckwheat, you can refer to the following methods:
1. Choose high-yield improved varieties. Mainly promote the improved buckwheat varieties Xi Qiao No. 1 and Xi Qiao No. 2.
2. Sow early at the right time and use mixed sowing. Sowing from the Beginning of Autumn to the End of Heat is suitable, and no later than the end of August. Before sowing, sun-dry for 1 day, soak the seeds in warm water at about 40°C for 10 minutes, remove them, and then sow. After drilling or even broadcasting, cover with a thin layer of soil. Buckwheat is a cross-pollinated crop. Mixed sowing of 2-3 excellent varieties can extend the flowering and pollination period, increase the hybridization rate and seed plumpness, and help increase yield.

3. Apply more phosphorus and potassium fertilizer. The growth period of autumn buckwheat is relatively short. In terms of fertilization methods, base fertilizer should be applied heavily, and phosphorus and potassium fertilizer should be increased. Base fertilizer should be the main application: apply 1000 kg of pig and cattle pen manure per mu, 15-20 kg of phosphate fertilizer, and about 30 kg of plant ash.
4. Manage early. Resist drought and drain waterlogging to ensure full and strong seedlings. After thinning to a stand, apply 5-6 kg of urea per mu as a seedling-promoting fertilizer; at the budding stage, remove the growth point of the main spike to promote branching. During the flowering period, carry out artificial pollination 2-3 times to promote seed setting and increase yield.
5. Prevent and control diseases and insect pests. Pay attention to preventing and controlling diseases and insect pests such as damping-off, ring rot, brown spot, and white mold, as well as voracious armyworms and meadow moths.
6. Harvest at the right time. Harvest when the seeds are 80% mature.
