Description

Technical Field

[0001] The utility model relates to the technical field of irrigation and fertilization, in particular to an irrigation and fertilization device for preventing and controlling cassava diseases and insect pests. Background Art

[0002] Cassava, also known as manioc or sweet potato, is a major feed crop and dry food. Cassava primarily grows in acidic soils in subtropical and humid tropical regions with favorable hydrothermal conditions. While organic matter accumulates quickly, it decomposes very quickly, resulting in generally low organic matter content, poor physical and chemical properties, and low water and fertilizer retention. Therefore, during cassava cultivation, organic fertilizers must be continuously applied to improve the soil. Cassava cultivation is also prone to frequent pests and diseases. Therefore, pest control is often performed on cassava.

[0003] The existing cassava pest and disease prevention treatment generally involves planters carrying spray boxes to spray pesticides on seedlings. This spraying method is not only inefficient, but also has a pungent smell and is toxic to humans, causing certain harm to the human body. In addition, when fertilizing cassava, most people manually spread fertilizer near the roots of the crop. This fertilization method relies entirely on the workers' experience to control the amount of fertilizer, which sometimes results in an excessive amount of fertilizer and sometimes a insufficient amount of fertilizer. It is impossible to accurately maintain the amount of fertilizer applied within a certain range. Therefore, this method does not meet existing needs. To address this issue, we propose an irrigation and fertilization device for cassava pest and disease prevention and control. Utility Model Content
