Description

Technical Field

[0002] Sugarcane is a tall, solid perennial herb with a strong and well-developed rhizome. It is widely grown in southern regions such as Fujian, Guangdong, Hainan, Guangxi, Sichuan and Yunnan. Sugarcane is a temperate and tropical crop. It is the raw material for making sucrose and can be used to extract ethanol as an energy substitute. Sugarcane is rich in sugar and water, as well as various vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to human metabolism.

[0003] Publication No. CN212851772U discloses a device for uniformly fertilizing sugarcane planting. The device opens a barrel lid, places fertilizer into the fertilizer barrel, then closes the barrel lids, inserts the bottom end of a manual shaft into a shaft fixing slot, and rotates the barrel lid until the fan-shaped platform on the barrel lid is aligned with the fan-shaped platform. The manual shaft is then rotated to change the opening and closing state of the fertilizer outlet, thereby controlling the flow of fertilizer. After fertilizing, the wheel is pushed to fertilize the next sugarcane seedling. However, this patent has the following problems in actual use:

[0004] Although the sugarcane planting uniform fertilization device can control the outflow of fertilizer by rotating the manual shaft and pushing the wheel forward to fertilize the sugarcanes one by one, freeing the user's hands and improving the speed and efficiency of fertilization, it is unable to accurately fertilize the roots of the sugarcane. During the fertilization process, part of the fertilizer will spread to the outside of the sugarcane, resulting in fertilizer waste and affecting the fertilization effect of the sugarcane.

[0005] Therefore, a sugarcane planting precision fertilization equipment is proposed to solve the above problems. Utility Model Content
