(b) drying seeds. Shaizhong has the effect of promoting germination and reducing disease. Usually selected on sunny morning morning, the seeds are spread on the sunny or sunny floor or on the mat, and the sun is continuously turned for 2-3 hours.
(c) Chemical seed dressing. The use of coated seeds or treatment of seeds before sowing can prevent diseases and prevent the harm of underground pests such as cockroaches and cockroaches.

(d) Apply the base fertilizer to ensure that the bottom squat. In order to meet the requirements of high-yielding maize fertilizer, 0.5-1.0 kg of zinc sulfate and 20 kg of nitrogen-potassium compound fertilizer can be used as base fertilizer per acre. If only one base fertilizer is used, the amount of nitrogen-potassium compound fertilizer should be increased to 35-40 kg; Well covered with water to prevent burning seedlings.
Second, paste seed sowing, early sowing when grab.
Early sowing is the key to increasing the yield of summer corn. It can fight for the growing season and avoid cold damage at the later stage to reduce various diseases. Select suitable high-yield and high-quality varieties, adapt them to local conditions, and broadcast early when robbed. The whole city strives to finish sowing before June 20th to lay a foundation for the high yield of corn. For wheat fields with a mu head below 300,000, corn can be interplanted, and corn can be planted within 2 days before wheat is harvested.
Third, to ensure a reasonable close planting.
Compact density density density of 4000-4500 strains / mu, flat density density of 3500-4000 strains / acre, seeding method is best to use the size of the row, the general line of 2.0 feet, small line 1.2 feet or 2.4 feet large line, Small line 1.2 feet.
