Picking seeds is a very critical step.

Selecting seeds is the first and crucial step in planting corn. Specifically, it is necessary to pick out the mold, rotten diseases, and rotten seeds of different sizes from the corn seeds to further ensure the seedling rate of corn. After all, good seed is what produces high-yield, high-quality corn. The choice of good seed is also very delicate. Generally experienced farmers will choose seeds based on four latitudes: seed purity, purity, germination rate, and seed moisture. For example, the purity is above 98%, seed germination rate is not less than 90%, and seed moisture is not higher than 14%. Therefore, corn seeds with high seed vigor and high germination rate are really good varieties.

Selected seeds do not rush to sow, but also need to dry the mix, improve the seed disease resistance and germination rate, so that the late corn seedlings more stable and stronger. Specific seed drying methods:Coated seeds can be placed directly on the balcony yard and other places in direct sunlight, while the uncoated seeds need to be placed additionally on the felt cloth, and then two consecutive days in the afternoon of the strongest sunlight for drying. Seed dressing is mainly for uncoated seeds. Seed dressing with seed coatings diluted directly with water will provide some control of pests and diseases such as corn spiders, corn stover and corn aphids.

Spring corn planting areas, mainly common in the northeast and Inner Mongolia. After last year's corn harvest, the land is plowed about 20cm deep and then harrowed, then waited until the next spring, when shallow plowing can be done before planting, and soil moisture loss can be prevented by plowing and harrowing. If there is no deep plowing before the last harvest, spring plowing should be done as early as possible. In summer corn-growing areas, the crop is in more than two seasons a year. If the last crop was wheat, you can sow directly after the wheat harvest, just clean up the straw that was dumped in the ground.

In the whole reproductive period of maize, the base fertilizer + follow-up fertilizer + foliar spray fertilizer **** the same to ensure the nutritional needs. Corn is a high nitrogen, high potassium, low phosphorus crop. So in the choice of base fertilizer, buy high nitrogen, low phosphorus and high potassium three yuan compound fertilizer can be.
