Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting, and in particular to a method for cultivating new corn varieties. Background Art

[0002] In the process of cultivating new corn varieties, corn seeds need to be sown into a cultivation tray with nutrient soil. The equipment needs to include a hole-making machine and a water-injection machine. The two sets of equipment operate independently, resulting in a complicated process when cultivating corn seeds, a large space occupied by the equipment, and a high overall production cost;

[0003] In addition, after the holes in the cultivation tray are opened, at least two employees are required to manually sprinkle corn seeds into the holes one by one, over and over again. This is not only time-consuming and laborious, but also prone to omissions. There is no guarantee that there are enough seeds in the cultivation tray. Summary of the invention
