Experts in the prevention and control of pests and diseases said that after the fall of autumn, corn is vulnerable to drill-type pests such as armyworms and corn borers. These pests will directly damage the corncob, which will cause the corn to die slowly. The height of corn in this period has already been almost one person high, so it is more troublesome to fight drugs by hand. If you use a drugs fight, you can achieve twice the result with half the effort.
Preventing the lodging of corn, if it falls, has a very large impact on its production. There are several main preventive measures. The first is to cultivate the soil and increase the number of supporting roots, so that the lodging resistance can be improved. Secondly, the potassium dihydrogen phosphate is applied to the page based on the application of potassium fertilizer. The toughness of the plants is greatly enhanced. At this time, if it is really encountering storms and other attacks that are difficult to confront, if there is a lodging, it is necessary to take active remedial measures, such as artificially raising the soil or cultivating the soil to restore itself.
Artificial pollination continues in high temperature days in summer, which affects the pollination of corn. This results in a low rate of corn cob seeding, so artificial pollination is necessary for this situation.
Corn in the drought-preventing and sorghum-grain period has a high demand for water. If water is scarce, it will affect the formation of the grain or the fruit is not full, and the yield will naturally decrease. Therefore, when the dry weather continues to occur, it is necessary to fill the water in time.
If the appropriate late harvest does not affect the second planting, the corn harvest period can be appropriately postponed, which will increase the grain yield of the corn kernels and increase the yield. So when the corn glutinous leaves become dry and loose, the grain begins to harden and appears golden yellow. When the grain milk line is completely invisible, the corn is in the ripening period, and the harvest is the highest. At the same time, the appropriate late harvest of corn is high in quality and the protein and amino acid content will increase.
