2. Variety selection: Use fine varieties with high cleanliness, strong germination potential and germination rate of more than 85%, such as noxious 1, nourishing 7, homozygous 2 and so on.
3. Seed treatment: Use coated seeds. If the seed is uncoated, it should be coated to prevent pests and diseases.
Second, sowing
1, sowing date: from late April to early May sowing, at the same time depending on soil moisture, according to local conditions, timely sowing.

Third, field management
1. Seedling stage: Timely seedlings, Dinglings, and cultivator weeding, 3–4 leaf time seedlings, 5–6 leaves, Dingmiao seedlings, and interplanting and seedlings for cultivating and weeding.
2. In the middle and late period: Dip time to carry out earth cultivation. Timely replanting fertilizer (9 - 10 leaves), generally can be combined with stubborn fertilizer, acres of topdressing urea 10 - 12 kg, can also be divided into two fertilizer, the first re-applying fertilizer - 7 9 kg, the second light application of 3 to 4 kg of booting fertilizer, on the plot of significant post-fertilization phenomenon can be followed by attacking grain fertilizer.
