Embodiment 1
[0021] In the middle of March, flood the saline-alkali land with flood water once, with an irrigation volume of 60m3 per mu, and dry it for 1 to 1.5 months to make the surface dry enough to enter. Apply 1000kg of soil fertilizer per mu, and then rotate till once to mix the soil and fertilizer. Rake pressure to keep moisture and keep the ground level; before sowing corn, it is treated with seed coating agent. Potassium sulfate, magnesium sulfate, zinc sulfate, α-sodium naphthalene acetate growth regulator, EDTA-2Na chelating agent, humic acid, peat, fungicides, and insecticides for mixed seed dressing treatment. After 3-6 hours of boredom, mix in the fungicide, and sow the seeds immediately after the seed dressing is completed;
[0022] According to the moisture situation after flood irrigation, choose to sow in early or mid-May; the sowing rate is 1.0-2.0kg / mu; plant in a row, the width of the row is 120-140 cm, and the height of the row is about 20 cm. ~150 cm, the narrow ro...
