After the corn sowing every year, there will be incomplete emergence, lack of seedlings broken ridge phenomenon. By analyzing the causes of this phenomenon, the author suggests that farmers' friends take the following five measures to prevent them.
Do not soak seed germination corn seed coating agent dissolved in water will not only fail, but also inhibit seed germination.
Don't sow deep-season corn with a suitable sowing depth of 3 to 5 cm. If the planting is too deep and the ground temperature is lower, it will be easier to plant seeds. Even if it can barely emerge, the seed will be buried too deeply and the seeds will consume a lot of nutrients before being unearthed. The unearthed corn seedlings will have a weak root system and absorb nutrients. Poor, forming weak seedlings. Therefore, when sowing the summer corn, the appropriate sowing depth should be maintained under the condition of ensuring soil moisture.
After the ban on burning of straw wheat was harvested, in order to facilitate farming, some farmers' friends left wheat straw in the field, paving the way for uniform ignition and burning. Because incineration kills microorganisms in the soil that are beneficial to crop growth, it also decomposes large amounts of nutrients in the soil and reduces soil fertility and soil moisture content, making it difficult for maize to emerge. Therefore, it is prohibited to burn straw after harvesting.
When bogey seed and fertilizer are applied regardless of artificial or animal power, the fertilizer is applied with the seed, and the phenomenon that the chemical fertilizer burns seedlings easily occurs. It should be about 10 centimeters apart. At present, most of the mechanically sown corn can be divided into seeds and fertilizers.
Insect control is a major pest during wheat maturation. Some peasant friends only pay attention to the harvest of wheat and the sowing of corn, and they often overlook the prevention and control of armyworm after sowing. Old mature larvae and re-emerged larvae left in the field began to bite corn just after they had emerged. When the armyworm occurs seriously, it will cause corn seedlings in the entire area to be eaten, and it will only destroy the replant. Therefore, after the emergence of corn, it was found to be harmful to the armyworm and it was necessary to control it in time.
