What are the reasons for the lack of corn seedlings?

What are the reasons for the lack of corn seedlings? Please give us an introduction and the reasons for the lack of maize seedlings caused by the prevention and control methods are as follows: do not soak seeds to promote germination after the corn seed coating agent is dissolved in water, it will not only fail, but also inhibit seed germination. Do not sow too deep summer corn. The suitable sowing depth is 3-5 cm. If the sowing is too deep, the ground temperature decreases, and it is easy to rett seeds, even if they can barely emerge, the seeds will be buried too deep, so that the seeds will consume a lot of nutrients before they are unearthed, and the roots of unearthed maize seedlings are weak and the ability to absorb nutrients is poor, forming weak seedlings. Therefore, when sowing summer corn, it is suitable to sow deep under the condition of ensuring soil moisture. It is forbidden to burn straw after wheat harvest, in order to facilitate farming, some farmers leave wheat straw in the field, spread it out and set it on fire. Burning will not only kill the microorganisms in the soil that are beneficial to the growth of crops, but also decompose a large number of nutrients in the soil, reducing soil fertility and water content in the soil, making it difficult for maize to emerge. Therefore, it is strictly forbidden to burn straw after wheat harvest. Avoid seed, fertilizer regardless of artificial, animal power sowing, fertilizer with the seed application, it is easy to burn the phenomenon of chemical fertilizer seedlings. Seed and fertilizer should be separated by about 10 centimeters. At present, most of the corn sown by machinery can be separated from seed and fertilizer, and the machinery of seed and fertilizer should be abandoned. The armyworm armyworm is the main pest during wheat ripening. Some farmers only pay attention to the harvest of wheat and the sowing of corn, and often ignore the prevention and control of armyworm after sowing. The mature larvae left in the field and the re-hatched larvae, after the emergence of the corn, began to bite the newly grown corn seedlings. When the armyworm is serious, it will cause the whole field of corn seedlings to be eaten up and can only be destroyed and replanted. Therefore, after the emergence of maize seedlings, it is found that there is armyworm harm, so it is necessary to apply pesticide in time to control.
