Park green space irrigation is a crucial part of park management and maintenance, playing a key role in keeping the vegetation in the park healthy and creating a beautiful landscape environment. The following is an introduction from the aspects of the composition of the irrigation system, commonly used equipment, irrigation methods, and management and maintenance:
Water Source: The water sources for park green space irrigation usually include urban tap water, surface water (such as rivers, lakes, ponds, etc.) and groundwater. To ensure the quality and stable supply of irrigation water, some parks also set up water storage tanks or water towers to store and regulate the water source.
Water Supply Pipeline: It consists of main pipes and branch pipes, which are responsible for transporting the water source to various areas in the park that need irrigation. The pipes generally use corrosion - resistant and pressure - resistant materials, such as PVC pipes and PE pipes. When laying, the layout is carried out reasonably according to the terrain of the park and the division of irrigation areas to ensure that water can be evenly distributed to each sprinkler.
Control Equipment: It includes valves, water meters, controllers, etc. The valve is used to control the on - off of the water flow and adjust the flow rate; the water meter is used to measure the water consumption for cost accounting and water resource management; the controller can realize the automatic control of the irrigation system, such as turning on and off the irrigation equipment regularly, setting the irrigation time and frequency, etc.
Sprinklers
Fixed Sprinklers: They are suitable for areas that require precise irrigation, such as flower beds and flower borders. Their spraying range is relatively small, but they can spray water accurately within the target area to avoid waste.
Rotary Sprinklers: Including gear - type sprinklers, etc. They have the characteristics of a wide spraying range and uniform water distribution, and are often used for the irrigation of large - area lawns and green spaces. Through the internal rotary mechanism, the sprinkler can rotate slowly within a certain angle range to evenly sprinkle water on the surrounding area.
Micro - sprinklers: They are mainly used in some plants that are not resistant to water impact or in places that require local fine - scale irrigation, such as the roots of shrubs and flowers. The micro - sprinklers spray fine water droplets and can irrigate with a small flow rate to avoid damage to plants.
Sprinkler Irrigation Machines: For large - area park green spaces, sprinkler irrigation machines are sometimes used for irrigation. Sprinkler irrigation machines can be divided into three types: fixed - type, semi - fixed - type, and mobile - type. The fixed - type sprinkler irrigation machine is installed in a fixed position and is supplied with water through a pipeline system, which is suitable for areas where cash crops are frequently irrigated (such as vegetable planting areas) or high - yield crop areas. For the semi - fixed - type sprinkler irrigation machine, the power machine, water pump, and main pipe are fixed, while the branch pipe and sprinkler can be moved. The mobile - type sprinkler irrigation machine has strong mobility and can be moved to different irrigation areas for operation according to needs. It is suitable for park green spaces with a large irrigation area and where it is inconvenient to lay fixed pipelines.
Spray Irrigation: It is one of the most common irrigation methods in park green spaces. Water is sprayed into the air through sprinklers to form fine water droplets and evenly sprinkle on the surface of the green space. According to the different needs of plants and topographic conditions, the spraying angle, range, and spraying intensity of the sprinklers can be adjusted to achieve precise irrigation.
Drip Irrigation: It is mainly used for some plants that have strict requirements on water and need precise water control, such as flowers and shrubs. The drip irrigation system slowly and evenly drips water into the soil at the roots of plants through the drippers installed on the pipeline. It can effectively save water resources, improve irrigation efficiency, and avoid water evaporation and loss.
Sub - Irrigation: It is a relatively advanced irrigation method. The irrigation pipeline is buried underground, and water slowly seeps into the soil through the small holes or gaps on the pipeline to provide water for the roots of plants. Sub - irrigation has the advantages of water - saving, energy - saving, and reducing soil compaction, but the construction cost of the system is high, and the maintenance is relatively complex, so it is less used in park green spaces.
Irrigation Time and Frequency: It is reasonably adjusted according to different seasons, weather conditions, and plant growth stages. In summer, when it is hot and dry, the number of irrigation times and the irrigation time usually need to be increased; while in winter or the rainy season, it should be appropriately reduced. Generally speaking, the lawn needs to be irrigated 2 - 3 times a week, and the irrigation time each time is determined according to the soil texture and the flow rate of the sprinkler to ensure that the soil is moist to the depth of the main root distribution layer. The irrigation frequency of flowers and shrubs is relatively high, and it needs to be adjusted according to the specific water requirements of the plants.
Equipment Maintenance: Regularly check all components of the irrigation system, including sprinklers, pipelines, valves, controllers, etc., and promptly repair or replace the damaged or blocked components. Clean the debris in the sprinklers and filters to prevent blockage from affecting the irrigation effect. Check and repair the pipelines for leaks to avoid water waste. At the same time, regularly maintain the irrigation equipment, such as adding lubricating oil to the rotating parts of the sprinklers and checking the battery power of the controllers, to extend the service life of the equipment.
Water Quality Management: Ensure that the quality of the irrigation water meets the requirements and avoid using water containing a large amount of sediment, impurities, or harmful substances for irrigation, so as not to block the sprinklers or cause damage to the plants. For surface water or groundwater sources, they may need to be treated by sedimentation, filtration, disinfection, etc. before being used for irrigation.
