Ag pipe drainage is an indispensable part of agricultural production. It is of great significance to maintain the normal growth of crops, improve soil aeration, prevent soil salinization and increase crop yields.
1. Discharge excess water: Ag pipe drainage system can effectively discharge rainwater, irrigation water and groundwater accumulated during crop growth, reduce the moisture content in the soil, and avoid crop death due to excessive moisture.
2. Prevent soil salinization: Through drainage, the groundwater level can be lowered, and the groundwater replenishment to the soil can be reduced, thereby reducing the risk of soil salinization.
3. Improve soil aeration: After drainage, the porosity in the soil increases, and the aeration improves, which is conducive to the growth of crop roots and the activity of soil microorganisms.
4. Maintain normal growth of crops: Suitable soil moisture and ventilation conditions are conducive to improving the photosynthesis efficiency and nutrient absorption capacity of crops, thereby increasing crop yields.
1. Open ditch drainage: dig open ditches on the surface to guide excess water from farmland into drainage ditches, and finally drain into rivers or lakes and other water bodies. This method is simple and easy to implement, but it occupies a large area and is easily restricted by terrain.
2. Concealed pipe drainage: bury drainage pipes underground to drain excess water from farmland through pipes. Concealed pipe drainage has the advantages of saving arable land and facilitating agricultural mechanization, but it has high investment and is prone to siltation.
3. Vertical shaft drainage: arrange vertical shafts in farmland, and reduce groundwater level and soil moisture content through well wall penetration and well pumping. Vertical shaft drainage is suitable for local low-lying areas, but cannot be used as a direct drainage method during irrigation.
There are many choices of materials for Ag pipe drainage, each with its own unique characteristics and application scenarios. Here are some common agricultural pipe drainage materials:
PVC pipe (polyvinyl chloride pipe):
Features: It has excellent corrosion resistance, weather resistance and pressure resistance, smooth inner wall, small water flow resistance, and can effectively improve drainage efficiency. At the same time, PVC pipe also has good flexibility, which is convenient for laying in complex terrain.
Application: It is one of the most common plastic pipes in farmland drainage systems, with low price and suitable for large-scale use.
PE pipe (polyethylene pipe):
Features: A lightweight, high-strength plastic pipe with excellent corrosion resistance, wear resistance and low temperature resistance. PE pipe also has good flexibility, can adapt to terrain changes, and reduce the difficulty of pipe installation. Its theoretical life can reach 50 years, which is an ideal pipe material for farmland drainage.
Application: It is widely used in farmland drainage systems, especially in places where it needs to withstand a certain pressure or requires a long service life.
PPR pipe (random copolymer polypropylene pipe):
Features: A safe plastic pipe with good heat resistance, pressure resistance and corrosion resistance. The inner wall of PPR pipe is smooth, the water flow resistance is small, and it can effectively reduce the water loss in the drainage process. At the same time, PPR pipe also has good connection performance, which is convenient for installation and maintenance.
Application: Although PPR pipe is not as widely used in farmland drainage as PVC and PE pipes, PPR pipe is a good choice in places with high water quality requirements.
Metal pipe:
Features: High strength, can withstand high-pressure water, and is often used to transport high-intensity water sources. Common metal drainage pipe materials include galvanized steel pipe, stainless steel pipe and aluminum alloy pipe. These metal pipes have the advantages of high strength, pressure resistance, corrosion resistance, long service life, and can completely resist ultraviolet radiation and oxidation corrosion.
Application: Due to the relatively high price, heavy weight, and high installation and maintenance costs, its application in farmland drainage is relatively limited. However, in some special occasions, such as when it is necessary to withstand great pressure or require extremely high corrosion resistance, metal pipes may be the best choice.
Aluminum-plastic composite pipe:
Features: The pipe consists of an inner PE pipe and an outer aluminum-plastic material, combining the advantages of metal pipes and plastic pipes, with the characteristics of corrosion resistance, not easy to age, light weight and good durability.
Application: It also occupies a certain market share in farmland drainage systems, especially in situations where corrosion resistance and weight need to be considered at the same time.
1. Topographic survey and design: Before designing the drainage system, it is necessary to accurately measure the farmland terrain to determine the location, slope and spacing of the drainage ditch or pipe.
2. Pipe material selection: Commonly used pipe materials include PVC pipes, PE pipes, etc. These materials have the advantages of corrosion resistance, wear resistance and long life.
3. Drainage outlet setting: The drainage outlet should be set in a low-lying area or a place that is easy to drain to ensure that excess water can be discharged smoothly.
4. System maintenance and management: Regularly clean the drainage pipes to prevent blockage; check whether the pipe joints are leaking and repair them in time; adjust the drainage volume according to crop growth and weather changes.
1. Intelligent management: Use modern information technologies such as the Internet of Things and big data to realize intelligent management and control of farmland drainage systems and improve drainage efficiency and accuracy.
2. Ecological treatment: By constructing ecological drainage facilities such as ecological ditches and wetlands, the ecological treatment of farmland drainage is realized, and the ecological environment of farmland is improved at the same time.
3. High efficiency and energy saving: Research and develop high-efficiency and low-energy drainage equipment and systems to reduce the energy consumption and cost of farmland drainage and improve the economic benefits of agricultural production.
Ag pipe drainage plays an important role in agricultural production. With the development of modern agriculture and technological progress, agricultural pipe drainage systems will become more intelligent, ecological and efficient, providing more reliable and efficient drainage guarantees for agricultural production.
