Seed treatment: select the seeds, remove the flat grains, large grains, try to make the seeds the same size. Seeding method: At present, sowing corn is mostly used for mechanical sowing. The fertilizer applied at the time of sowing is sown in a very narrow furrow. Although the fertilized material has a certain distance from the corn seed, it is because the fertilizer applied mechanically is very concentrated. Concentration is very high. Little attention is paid to the phenomenon of burning seedlings. Therefore, when planting spring corn, try to adjust the spacing between seeds and fertilizers to avoid fat burning. Depth of sowing: The spring wind is easy to run. It is necessary to grasp the suitable sowing depth according to the public opinion. If it is too deep, it will not be easy to emerge if it is exposed to low temperatures, soil compaction, etc. If it is too light, it will not germinate if it is exposed to drought and the water content is too low. General broadcast depth 3 ~ 5? Is appropriate, slightly sandy soil, clay soil slightly shallow. After sowing, the soil should be promptly repressed, and then a new high-fat membrane should be sprayed to protect the surface, and the density of surface compaction should be activated to increase the emergence rate.
