Short-term sowing of ⑵. The seeds were sown from late April to early May in central Shanxi, generally no later than May 15.
⑶ reasonable close planting. The suitable planting density for spring sowing in central Shanxi is 8000-10000 plants per mu, and the sowing rate is 5-6 kg per mu, while in the south, the suitable planting density is 1.2-15000 plants per mu, and the sowing rate is 6.7-8 kg.
⑷ field management. Timely seedling, fixed seedling, timely ploughing and weeding, 7-10 kg chlorine fertilizer per mu combined with watering at the beginning of flowering, timely control of heart-eating insects in the first and middle of August, and timely harvest after maturity.
