In modern agriculture, the application of agricultural irrigation pipelines spans urban and rural indoor and outdoor water supply and drainage, rural water improvement, field irrigation, brine pipelines in the salt industry, water supply in the breeding industry, mine ventilation, water supply and drainage projects, garden sprinkler irrigation equipment, and various other large and small projects. These pipeline systems are essential infrastructure for farmland irrigation and are crucial for improving water resource utilization and agricultural yield.
There are generally three types of irrigation methods in agriculture and animal husbandry: traditional surface irrigation, ordinary sprinkler irrigation, and micro-irrigation. Different irrigation methods correspond to different agricultural irrigation pipelines and have varying levels of water resource utilization. Below, we will introduce several common agricultural irrigation pipelines in detail.
The micro-spray belt is a new type of micro-irrigation equipment, also known as "spray irrigation belt," "micro-spray belt," "sprinkler belt," "sprinkler pipe," "multi-hole soft pipe," and so on. It transports water to the field using agricultural irrigation pipelines under pressure and then releases it through the micro-spray belt's water outlets. With the interplay of gravity and air resistance, it creates a fine rain-like spray effect. The micro-spray belt is mostly used for growing vegetables, mushrooms, nurseries, orchards, flowers, and greenhouse crops.
The drip irrigation belt utilizes plastic pipes in the agricultural irrigation pipeline (drip irrigation conduit) to deliver water to the crop roots for localized irrigation through orifices or drippers with a diameter of about 10mm. This type of agricultural irrigation pipeline uses very small outflow orifices or drippers to deliver water drop by drop, evenly and slowly, near the crop roots. Drip irrigation belts come in types such as patch-type drip irrigation belt, embedded cylindrical drip irrigation pipe, labyrinth-type drip irrigation belt, and blue track drip irrigation belt. They are simple to operate and are widely used in greenhouse and plantation irrigation.
PE irrigation pipe, or polyethylene irrigation pipe, connects its pipeline systems using electrofusion, with a joint strength higher than the pipe body strength. This type of agricultural irrigation pipeline has characteristics such as reliable connection, good low-temperature impact resistance, corrosion resistance, aging resistance, and low water flow resistance. The wear resistance of PE irrigation pipes is four times that of steel pipes, and their low-temperature impact resistance is excellent, making them less prone to brittleness during winter construction. Polyethylene can resist erosion by various chemical media.
PVC irrigation pipe has excellent acid, alkali, and corrosion resistance. It can deliver more reasonable irrigation water quantities according to the growth needs of crops, ensuring timely and adequate irrigation. This type of agricultural irrigation pipeline is widely used in urban and rural indoor and outdoor water supply, rural water improvement, farmland irrigation, brine pipelines in the salt industry, water supply in breeding farms, mine ventilation, water supply and drainage, garden sprinkler irrigation, and other large and small projects.
In summary, the four types of agricultural irrigation pipelines introduced above each have their unique advantages and application scenarios. In practical applications, it is necessary to comprehensively consider the crop requirements, water resource status, terrain characteristics, and economic costs to choose the most suitable agricultural irrigation pipeline system, thereby achieving efficient water conservation and sustainable agricultural development.
