How to choose the spraying mode of adjustable micro sprinkler

In irrigation design, adjusting the spraying mode of adjustable micro sprinklers is a crucial link, which directly affects the uniformity of irrigation effect and the utilization efficiency of water resources. Reasonable spraying mode can not only meet the growth needs of different plants and crops, but also reduce water waste and evaporation loss, so as to achieve the goal of water-saving and efficient irrigation.

In practical applications, the spraying mode of adjustable micro sprinklers is mainly reflected in the adjustment ability of spraying angle and spraying radius. The choice of spraying angle directly affects the coverage range of water flow, which can not only achieve local irrigation, but also meet the needs of uniform irrigation of large areas. The adjustment range of spraying angle usually ranges from 30 degrees to 360 degrees, and users can flexibly adjust it according to the specific shape and area of ​​the irrigation area. For small areas or corner areas, using a smaller spraying angle helps to concentrate water flow and avoid water flow wasting in non-target areas; for irrigation of large areas or central areas, a larger spraying angle or even full-angle spraying should be selected to ensure that the water flow evenly covers the entire area. The adjustment of the spraying radius determines the propagation distance of the water flow, which is usually determined by the design of the nozzle. Users can achieve different spraying distances by adjusting the rotation of the nozzle or changing the nozzle. Reasonable selection of the spraying radius can ensure that the water flow effectively covers the target area and prevents insufficient or excessive water.

When choosing a spraying method, water pressure conditions must also be considered. Under low water pressure conditions, choosing a micro-sprinkler with a shorter spraying distance and a smaller spraying angle can ensure the stability and uniformity of the water flow; while under high water pressure conditions, a nozzle with a longer spraying distance and a larger spraying angle can be selected to achieve a wider coverage range. When the water pressure is insufficient, the use of a pressure regulating device or an additional pressure compensation device can ensure the stability of the spraying effect. In addition, climatic factors also have an important impact on the choice of spraying methods. In arid areas or hot seasons, the use of spray-type micro-sprinklers can increase the evaporation area of ​​water, thereby improving the soil wetting effect; while in humid areas or rainy seasons, it is particularly important to reduce the spraying range and frequency to avoid excessive wetting and waste of water resources.

Soil properties are also an important factor in determining the spraying method. Sandy soil has good drainage, so it is suitable to use a larger spraying distance and a larger spraying angle to ensure that the water can penetrate deep into the soil layer; while clay or clay soil has poor drainage and is prone to water accumulation, so a smaller spraying range and a lower spraying pressure should be selected to avoid excessive soil moisture causing root diseases. The water requirements of different crops also vary. Plants with shallow roots, such as lawns and vegetables, are suitable for micro-sprinklers with low spraying distances and smaller angles to ensure that the water is concentrated in the root area; while deep-rooted plants such as trees or shrubs can choose nozzles with a larger spraying distance and a wider angle to meet the water needs of their deep roots.
