How to choose the water output of the drip irrigation pipe according to crop needs?

Drip irrigation pipes are widely used in greenhouses, sheds, and field crops, especially for economic crops such as vegetables, fruits, flowers, nurseries, and landscaping. They can save water and fertilizer and improve economic benefits.

1. Consider the crop type

Different crops have different water requirements, so the water output of the drip irrigation pipe needs to be adjusted according to the type of crop.Different crops have different water requirements, so the water output of the drip irrigation pipe needs to be adjusted according to the type of crop.

For example, vegetable crops usually need drip irrigation 1 to 2 times a day, with a drip volume of 0.5 to 1 liter each time. Therefore, for vegetable crops, it is recommended to choose a drip irrigation pipe with a moderate dripper flow, such as a drip irrigation pipe with a flow rate of 1 to 2 liters per hour. This ensures that vegetable crops get enough water while avoiding the occurrence of root diseases caused by excessive water. Fruit crops such as apples and bananas need drip irrigation 2 to 3 times a day. It is recommended to choose a drip irrigation pipe with a slightly larger dripper flow. This is conducive to the growth and development of the fruit. Grain crops such as corn and rice have a relatively low drip irrigation frequency, and you can choose a drip irrigation pipe with a relatively large dripper flow, but it should also be determined according to the growth needs and soil conditions of the specific crops.

2. Consider soil conditions

The type and texture of the soil will also affect the water output of the drip irrigation pipe.

Heavy soil: A dripper with a smaller flow rate should be selected to avoid the outflow being greater than the saturated water conductivity of the soil, which will cause the dripper outflow to be blocked.

Light soil: A dripper with a larger flow rate can be selected to meet the water needs of crops.

3. Selection of dripper flow rate

The dripper is a key component for controlling water flow, and its flow rate directly affects the water output of drip irrigation. The flow rate of common drippers ranges from 1 to 4 liters/hour, but the specific flow rate should be selected according to plant needs and soil conditions.

4. Consideration of the length of the drip irrigation belt

The length of the drip irrigation belt will also affect the water output. A longer drip irrigation belt means more drippers, which may increase the total water output. However, a drip irrigation belt that is too long may cause a drop in water pressure and affect the irrigation effect. Therefore, when choosing the length of the drip irrigation belt, it is necessary to comprehensively consider factors such as the water demand of crops, soil conditions, and the water pressure of the irrigation system.

5. Adjustment of practical application

In practical applications, it is also necessary to adjust according to the design and actual conditions of the drip irrigation system. For example, the drip irrigation effect can be optimized by adjusting parameters such as the spacing and number of drippers and the pressure of the irrigation system. At the same time, it is also necessary to regularly check and maintain the drip irrigation system to ensure its normal operation and meet the water needs of crops.

In summary, the water output of the drip irrigation pipe needs to comprehensively consider factors such as crop type, soil conditions, dripper flow, drip irrigation belt length, and irrigation time. Through scientific and reasonable selection and adjustment, it can be ensured that the drip irrigation system meets the water needs of crops and improves irrigation efficiency and crop yield.
