First, the most suitable sowing depth of anti-seedling deep summer corn is 3 to 5 cm. If the planting is too deep and the ground temperature is lowered, it will be easier to plant seeds. Even if it can barely emerge, the seeds will be buried too deeply. The seeds will consume a lot of nutrients before being unearthed. The roots of unearthed corn plants will have weak ability to absorb nutrients and form a poor environment. Weak seedlings. Therefore, when sowing summer corn, sowing depth should be minimized under the condition of ensuring soil moisture. Second, after the ban on burning straw wheat harvest, in order to facilitate farming, some growers will leave the wheat straw in the field, spread evenly and burn. After the fire is burned, it will kill microorganisms in the soil that are beneficial to crop growth due to the effect of high temperature; it will also decompose large amounts of nutrients in the soil and reduce the soil fertility and moisture content in the soil, making it difficult for maize to emerge. Therefore, it is harvested in wheat. It is prohibited to burn straw afterwards. Third, the avoidance of seed fertilizer, regardless of the use of artificial, animal power when sowing, fertilizer applied with the seed, it is prone to chemical fertilizer burning phenomenon. It should be about 10 centimeters apart. Most of the current mechanical sowing of corn can do species, fertilizer separation. 4. Insecticides against the armyworm are the main insect pests during wheat maturation. Some growers only pay attention to the harvesting of wheat and the sowing of corn, and often ignore the prevention and control of armyworm after sowing. The mature larvae and newly hatched larvae left in the field, after corn emerged, they began to bite the corn seedlings that had just grown. When the stickworms were severe, they would eat up the entire field of corn seedlings. Re-destroy. Therefore, after the emergence of corn, it was found that the insects had eaten bites and they had to apply the medicine in time.

Every year, there are some corn growers have emerged after the emergence of incomplete seedlings, lack of seedlings broken ridge phenomenon. We should find out the reasons for this phenomenon and take preventive measures in a targeted manner.
