- Dry the seeds for 2 to 3 days, and soak the seeds for 4 to 6 hours before sowing to facilitate uniform and neat emergence. Arrange the plant spacing according to the density of 3500-4000 seedlings required for 667 square meters, use Manual Seeder to drill 5 cm deep holes, and then sow 1 to 2 selected corn seeds per hole, cover 3 cm of soil after sowing, and then pour masking water , To ensure that all seedlings are sown. The seedlings are fixed during the period of 5 to 6 leaves.
2. Within 1 to 2 days after the corn is sowed, 667 square meters are sprayed with glyphosate and 50% acetochlor with 150 ml of water in a closed spray, which can effectively control weeds.
3. Due to the high temperature in the early period of autumn corn and the shortening of the growth period of corn, base fertilizer should be applied again. After sowing, use Rice Planting Machine to drill 15 cm deep holes between the corn plants on the ridge surface. Apply 40 kg of multi-component fertilizer to 667 square meters. After the seedlings are fixed at the 5-6 leaf stage, 15 kg of urea is applied as seedling fertilizer. In the 10-12 leaf stage, 15 kg of urea is applied on 667 square meters. Timely drainage and irrigation.
4. Without affecting the next season's crops, harvest as late as possible to fully extend the corn filling time, increase grain weight, increase corn yield, and improve corn quality.
Autumn corn should be broadcast without tillage after mid-July. After the first crop of corn is harvested, pay close attention to the time to clean the fields, sowing early is the key, and deep ploughing is generally not required.
