Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment, and in particular relates to a water-saving fertilization device for corn planting. Background Art

[0002] Corn is widely planted in both the north and south of my country as an important crop. In order to ensure the yield of corn, it is generally necessary to fertilize the corn seedlings several times during the growth period. After fertilization, the corn needs to be flooded to ensure that the corn seedlings can fully absorb fertilizer. However, in the water-deficient areas of northwest my country, there is no condition for flooding, so fertilizer is usually fully mixed with a certain amount of water and then sprayed into the corn field. The Chinese utility model patent with publication number CN219421588U discloses an agricultural water-saving fertilization mechanism, which fully mixes fertilizer and water in a water tank and then sprays them through a sprinkler head, thereby achieving the purpose of water saving. However, the spraying mechanism of the water-saving fertilization mechanism adopts a method of directly spraying fertilizer and water toward the corn seedlings, and the spraying position cannot be adjusted, which not only makes it impossible to accurately spray fertilizer and water near the root system of the corn seedlings, but also splashes fertilizer and water on the corn seedlings and easily causes the phenomenon of burning seedlings.
