Drip irrigation is a form of micro-irrigation. It is a drip irrigation method in which water is pressurized, filtered, delivered to the dripper through a low-pressure pipeline, and dripped into the root of the crop. The fertilizer to be applied is dissolved in water. Irrigation is a drip fertigation. Advantages of drip fertigation:
1. Improve the utilization rate of fertilizers. Conventional fertilization, fertilizer utilization rate is only 30% - 40%, drip fertigation, fertilizer utilization rate of more than 80%, more than one-half more than conventional fertilization.
2, water saving, uniform irrigation. It is one-half of the water-saving water than the large water temperature, and the uniformity can reach 80%----90%.
3. Reduce the temperature inside the shed, reduce pests and diseases, suppress weeds, and improve crop quality.
4. Reduce soil degradation (such as lower soil pH, secondary salinization of soil) and groundwater pollution.
5. Save labor. Each mu of greenhouse can reduce the number of workers who work in watering, fertilizing and spraying.
6. Increase production and increase income. Generally, the yield can be increased by 15%----20%.
As a modern agricultural technology that combines water and fertilizer supply through irrigation, drip fertigation technology can not only achieve intensive use of water and fertilizer resources, but also maximize crop yield by accurately controlling irrigation amount, fertilization amount and irrigation and fertilization time. And the quality is optimized, and it also has the least pollution to the environment. The promotion of drip fertigation technology in the greenhouse of Jiangcaiwen Village, Huangzhai Town, Huang County is a clear example. Fertilization by drip irrigation is beneficial to alleviate the occurrence of grape diseases and insect pests, promote the improvement of grape yield and quality, and the economic benefits are obvious.
