1, choose a good variety. Choose a high quality coated seed suitable for the local area.
2, seed processing before sowing. Seeds should be sunned for 1~2 days before sowing, which is beneficial for seed water absorption after seeding, enhancing seed coat permeability and seed enzyme activity and artificial grain selection, removing seeds with obvious defects such as weak grains, broken grains, etc. Field emergence rate.
3, timely sowing. When the ground temperature is stable at 10 ~ 12 °C, sowing, the same depth, to ensure a full seedling broadcast. If the planting is too early and the ground temperature is low, the corn sprouts and sprouts slowly. It is easy to cause the seeds to rot and not to emerge normally. If the planting is too late, the ripening period will be delayed and the yield will be affected.
4, field management. Intensive cultivation, leveling of land, deep plowing of land before planting, smoothing and screeding, uniform ridging, appropriate repression, and seeding to be consistent in depth and depth, guaranteeing complete planting of seedlings. Sowing the soil strictly to achieve "Sui, Ping, Qi, loose, broken, net" six-character standard, and deep basal fertilizer, mastered in 15cm, mouth fertilizer should be separated from the seeds, applied in the seed below 3-5cm, to avoid Over-fertilization results in burning and burning seedlings.
5. Control pests. Maize seed coating has better control effect on the underground pests, or mixed with 5% phosphorus plus mouth fat and added to the side of the seeder and the seeds at the same time. It can not only prevent pests but also solve the phenomenon of earthworm seedlings. Seedlings are vulnerable to bite hazards after unearthing, and areas with severe pests should be treated with soil (with 5% of insecticidal double granules 1-1.5 kg plus fine earth 15-25 kg, or 50% phoxim emulsion 100 ml Fine slag 15-25 kilograms, sprinkled on the ground before the arable land, plunged into the ground, can kill maggots and gold needle worms) or spray control.
6. Safe use of herbicides. In the application of soil-enclosed herbicides, attention must be paid to the conditions of temperature and soil moisture, and should be used when the soil temperature exceeds 12°C and the humidity is appropriate. If the soil temperature after sowing is low, it is recommended to use post-emergence herbicides such as Jade. The application amount and concentration of herbicides must be applied strictly in accordance with the instructions for use, to avoid phytotoxicity caused by large application amounts and high concentrations.
7. Timely management. After seedling emergence, corn was found to lack seedlings, and timely transplanting or replanting was necessary to strive for full seedlings and pay attention to cultivating and weeding to lay a foundation for high yields.
