The wheat sowing season is fast approaching. In order to achieve high wheat yield, the following points must be observed before and after sowing: 1. Select high-yield, disease-resistant and lodging-tolerant varieties, and in the north, select cold-resistant winter varieties, such as medium wheat. 175, round 518 and so on. 2. Before sowing, regardless of whether the seeds are kept or purchased, germination tests should be conducted in advance to select seeds with high germination rate and good germination potential. At the same time, seed dressing should be carried out to prevent and control underground pests and seedling diseases. 3. Fine soil preparation before sowing and adequate base fertilizer. The nitrogen fertilizer must be added to the plots where the straw is returned to the field to prevent the straw rot and the seedlings from competing for fertilizer during the seedling stage. 4. Must be made when planting so as to ensure sufficient planting. 5. The amount of sowing when sowing should be appropriate, according to the germination of the seed, sowing date to determine the appropriate amount of wheat sowing, in the appropriate sowing date generally about 15 kilograms sowing, after the increase of sowing every day about 0.5 kilograms. 6. When planting, the depth of the seed should be the same, the cover should be the same, the seed should be uniform under the seed, and the seed with seed fertilizer should be seeded separately to prevent the seedling from affecting the emergence of wheat. Wheat is a "seven-point, three-in-one", and the species is the key. Taking the above measures can ensure that the wheat seedlings are seedlings, seedlings, seedlings, seedlings and seedlings, and lay a solid foundation for wheat production.
