2. Choose according to the crop type:
- Short-stalked crops: For short-stalked crops such as wheat and vegetables, usually choose nozzles with a wide spraying range and good atomization effect, so that the entire crop area can be evenly covered and will not cause a large impact on the crops. For example, you can choose a scattering nozzle or a low-pressure rotary nozzle.
- Tall-stalked crops: For tall-stalked crops such as corn and sorghum, you need to choose nozzles with good penetration ability so that water can be sprayed to the middle and lower parts of the crops. Nielsen's A3000 rotary nozzle has strong water flow penetration and is suitable for inter-row spraying of tall-stalked crops.
- Crops that are sensitive to water: For crops that are sensitive to water, such as flowers and tea, choose nozzles that can accurately control the amount of water and the intensity of water spraying to avoid damage to crops due to excessive or insufficient water. You can consider nozzles equipped with pressure regulators to adjust the spraying pressure and flow according to the needs of the crops.
3. Consider irrigation needs:
- Irrigation area: For large irrigation areas, you need to choose nozzles with long range and large flow to improve irrigation efficiency. At the same time, it is necessary to ensure that the number and arrangement of sprinklers can meet the needs of the entire irrigation area to avoid irrigation dead corners.
- Irrigation frequency: If the irrigation frequency is high, it is necessary to select sprinklers with reliable quality and good durability to reduce the frequency and cost of replacing sprinklers. In addition, the anti-clogging performance of the sprinkler should be considered to avoid affecting the irrigation effect due to the clogging of the sprinkler by impurities in the water.
- Special irrigation requirements: If there are special irrigation requirements, such as fertilization and spraying, it is necessary to select sprinklers that are suitable for them. For example, some sprinklers can achieve uniform spraying of fertilizers and pesticides through special designs.
4. Choose according to the performance parameters of the sprinkler:
- Working pressure: The working pressure of the sprinkler should match the water supply pressure of the sprinkler. If the working pressure of the sprinkler is too high and the water supply pressure of the sprinkler is insufficient, the sprinkler will not work properly; conversely, if the working pressure of the sprinkler is too low and the water supply pressure of the sprinkler is too high, it will cause waste of water resources and damage to the sprinkler.
- Installation height: Generally speaking, the higher the installation height of the sprinkler, the wider the coverage of the water spray and the higher the irrigation uniformity. However, the installation height should also be determined according to the structure of the sprinkler and the height of the crop to avoid the sprinkler being too high to affect the stability of the sprinkler or cause unnecessary damage to the crop.
5. Pay attention to the quality and performance of the sprinkler:
- Brand and reputation: Choose a sprinkler from a well-known brand, the quality and performance are more guaranteed. You can learn about the reputation and performance of sprinklers of different brands by consulting other users, reading relevant product reviews and technical information, etc.
- Wind resistance: In areas with strong winds, you need to choose a sprinkler with good wind resistance to ensure the accuracy and uniformity of water spraying. Sprinklers with good wind resistance usually have special designs, such as wind shields or weighted bases.
- Durability: The sprinkler needs to be exposed to the outdoor environment for a long time and is easily affected by factors such as sunlight, rain, wind and sand. Therefore, you should choose a sprinkler with good durability, such as a sprinkler made of corrosion-resistant materials.
