What Are the Different Types of Field Irrigation?

Scientific irrigation embodies the scientific nature of irrigation and makes the existing water-saving irrigation more scientific. Through reasonable irrigation calculations, appropriate irrigation systems are formulated and maintained through effective management systems to optimize irrigation goals. Make the ratio of output value to water consumption reach the highest point. However, scientific irrigation emphasizes the scientific nature of irrigation, adding strict scientific basis on the basis of water saving, mainly including the following aspects: (1) the scientific nature of the irrigation system; (2) the scientific nature of the design scheme; (3) ) Scientific operation management.

Scientific irrigation

The scientificity of the design scheme is mainly reflected in the rationality of the irrigation district planning, the scientificity of the pipeline selection, and the strictness of the installation engineering.

With the development of urban construction, landscaping and the improvement of citizens 'environmental awareness, a large area of ornamental lawns, recreational green spaces and urban road greening have also gradually emerged in the cities. At the same time, the contradiction between green water and urban residents' domestic water Outstanding, therefore, it is imperative to actively promote a scientific and efficient water use method-garden sprinkler irrigation.

Scientific and efficient irrigation is not only reflected in the rationality of the installation and selection of irrigation devices (nozzles, micro-nozzles, etc.), but also more importantly how to achieve accurate and simple automatic control. However, achieving this goal is not simple. It involves four major needs of current garden irrigation systems: to meet the water needs of different types of garden plants, to meet water conservation and energy conservation, to meet the need to save manpower management costs, and to meet the needs of green space landscape formation. demand. <BR> <STRONG>

Scientific irrigation meets the requirements of different plants

Garden landscape is composed of many types of plants, such as lawns, flowers, shrubs, trees, etc. Garden irrigation must not only meet uniform irrigation, but more importantly, it must also meet the different needs of different types of plants on irrigation methods, irrigation wetting depth, and irrigation cycle. <BR> For lawns with a high level of maintenance, irrigation is required every day, and a wetting depth of more than ten centimeters is sufficient. In order to maintain a high-quality lawn with uniform color, the spraying of the irrigation system should have good uniformity. For flowers, it is required to have a high degree of atomization of water droplets and different management measures in different growing seasons. The irrigation methods of shrubs and trees have similarities. For example, foliar spraying cannot be performed, and water should be directly irradiated near the roots of the plants. However, trees have obvious trunks, and shrubs are mostly clustered. Different. From this point of view, how to irrigate a green area with mixed trees, grasses, and grasses is a very complicated problem, which requires the irrigation designers to treat them separately and adopt different schemes.

Scientific irrigation meets water and energy requirements

Garden irrigation can save water and energy by improving the effective utilization of water and reducing ineffective irrigation. The water saving of garden irrigation is reflected in the accuracy of the irrigation of the sprinkler, so as not to "overspray" and "leakage"; on the other hand, the precise control of the irrigation time, not only to meet the needs of plants The water quantity accurately controls the irrigation time, and the more important thing is whether it can accurately adjust the irrigation time according to the weather conditions on the day of irrigation.

Requirements for scientific irrigation to save management costs

With the increase of staff salaries in recent years, the cost of greening and maintenance is getting higher and higher, and the management cost of irrigation has also encountered such problems. Increasing wages of workers and uneven professional qualities and responsibilities of irrigation staff have driven the development of irrigation management towards automation and minimizing labor. The current automatic management system of irrigation system is powerful. For the system operator, it is more and more simple and convenient. It can even achieve unmanned management, which greatly saves manpower and management. Of course, there is still a lot of room for improvement in unmanned management in the future.

Scientific irrigation meets certain landscape requirements

We often see these pictures: in the middle of the green space, workers hold leather pipes in their hands to water various plants; on congested roads, green chemical people drive sprinklers to sprinkle water on the roadside plants; a beautiful green field stands in the middle On the ground, a pole mounted with a rocker nozzle was erected. Frankly speaking, these sights are not beautiful.

Now that there is a solution, the underground sprinklers have been widely recognized by the society. The pipes and sprinklers are buried in the ground. The sprinklers will automatically eject when spraying, and will retract to the ground after spraying. In addition, the underground sprinklers have a variety of spraying water types, and uniform, thin water mist displays colorful rays under the sun. Who can say that large-area spraying is not a beautiful landscape? In addition, the green space with buried sprinkler heads is very convenient for daily grass cutting operations, and because the entire system is buried underground, it is not easy to be damaged by natural or man-made damage, and the service life will be extended. ^[1]
