Agricultural hoses usually use the following main materials:

1. Polyvinyl chloride (PVC) hose: PVC hose is one of the most common irrigation hoses in the agricultural field. They are durable, weather resistant and relatively low cost for general irrigation and water transport tasks. PVC hoses have different wall thicknesses and diameters, which can be selected according to needs.

2. Polyethylene (PE) hoses: PE hoses are also common in agricultural irrigation. PE hose has higher elasticity and durability, and can adapt to a certain degree of underground installation and water pressure. They are suitable for longer distance water delivery and drip irrigation systems etc.

3. Drip Irrigation Hose: A drip irrigation hose is a specially designed hose used in drip irrigation systems. They are usually made of polyethylene material and have a precise drip function, which can effectively infuse water droplets to the roots of plants and improve water use efficiency.

4. Rubber hoses: In some cases, rubber hoses may also be used for agricultural irrigation, especially where greater durability and corrosion resistance are required.

These materials are widely used in agriculture, and the choice depends on factors such as irrigation system requirements, budget, use environment and how water is conveyed and distributed. When choosing a material, hose durability, fit, cost, and compatibility with water quality and chemicals should be considered.
