The Main Features and Advantages of Drip Irrigation

Drip irrigation is by far one of the most water-efficient irrigation techniques for nursery irrigation. But because of its high price, it was once called "expensive technology". In recent years, with the wide application of drip irrigation belts, "expensive technology" is no longer expensive and can be applied in nurseries. Here is a brief introduction to the technology of how to arrange and construct drip irrigation in nurseries, and you can refer to the implementation.

Drip irrigation is the use of plastic pipes to send water through orifices or drippers on capillary tubes with a diameter of 10mm to the roots of crops for local irrigation. It is currently the most effective form of water-saving irrigation in arid and water-deficient areas.

Ⅰ. The main features of drip irrigation

1. The water utilization rate reaches 95%, which has a higher water-saving and yield-increasing effect than sprinkler irrigation. At the same time, combined with fertilization, the fertilizer efficiency is more than doubled;

2. The amount of irrigation is small, the flow rate of the irrigation device is 2~12 liters per hour, so the duration of one irrigation is longer;

3. The irrigation period is short, small water irrigation can be achieved, and the required working voltage is low, the irrigation amount can be controlled more accurately, and water will not be wasted.

Ⅱ. The advantages of drip irrigation

1. Water saving

Drip irrigation is a full-pipeline water delivery and local micro-irrigation, which reduces the infiltration and loss of water to a minimum. At the same time, the water required by the crop area can be supplied in a timely manner, and there is no loss of peripheral water, so that the water utilization efficiency is greatly improved.

2. Save fertilizer

Drip irrigation can be easily combined with fertilization, that is, the chemical fertilizer is dissolved and poured into the irrigation system. Because the chemical fertilizer is combined with the irrigation water, the fertilizer nutrients are directly and evenly applied to the root layer of the crop, which truly realizes the synchronization of water and fertilizer, and greatly improves the effective utilization of fertilizer. At the same time, due to small-scale local control and micro-irrigation, the leakage of water and fertilizer is less, and the amount of chemical fertilizer application can be saved.

3. Save labor

The drip irrigation system is only controlled manually or automatically through the valve, and combined with fertilization, which significantly saves labor input and reduces production costs.

4. Control temperature and humidity

Drip irrigation belongs to local micro-irrigation, most of the soil surface is kept dry, and the dripper evenly and slowly supplies water to the root soil layer, which has obvious effects on maintaining and rising ground temperature, reducing water evaporation, and reducing indoor humidity.

Due to the small orifice, the slow flow rate, the long irrigation time and the small change in soil moisture, the soil in the root zone can be controlled to keep close to the crop growth temperature for a long time. Due to the control of indoor air humidity and soil temperature, the occurrence of pests and diseases can be significantly reduced, thereby reducing the use of pesticides.

5. Maintain soil structure

Water slowly and evenly penetrates into the soil, which protects the soil structure and forms a suitable soil water, fertilizer and thermal environment.

6. Improve quality, increase production and efficiency

Due to the reduction of the application amount of water and fertilizer, pesticides and the occurrence of pests and diseases, the quality of the product can be significantly improved. Compared with the traditional irrigation method, the use of drip irrigation can greatly increase the product output, and the time to market is earlier, and the economic and social benefits are significant. Drip irrigation technology meets the requirements of high-yield, high-efficiency, and high-quality modern agriculture, which is the essential reason for its existence and vigorous promotion.
