Two kinds of integrated irrigation methods of water and fertilizer are common in grape planting
In grape planting, the integrated irrigation technology of water and fertilizer has gradually become the mainstream choice of grape planting with its unique advantages. This technique ensures balanced growing conditions by precisely controlling the supply of water and nutrients. In the integrated irrigation of water and fertilizer, drip irrigation and hanging spray are two common irrigation methods, both of which play an indispensable role in grape planting.
Drip irrigation: Drip irrigation is a water-saving irrigation technique that delivers water directly to the roots of crops. In grape growing, drip irrigation systems slowly and evenly drip water into the grape root zone through pipes and drippers, ensuring that water is supplied directly to where it is most needed. This irrigation method not only saves water resources, but also effectively avoids soil compaction, maintains good soil ventilation, and is conducive to the growth of grape roots. At the same time, the drip irrigation system can also be combined with fertilization equipment to achieve integrated management of water and fertilizer, improve the utilization rate of fertilizer, and reduce fertilizer waste and environmental pollution. However, drip irrigation systems also have certain limitations. Because drip irrigation is local irrigation, if not properly managed, it is easy to cause the accumulation of soil salt and affect the growth of grapes.
Hanging irrigation: Hanging irrigation is a type of irrigation in which water is sprayed into the air. In viticulture, a sprinkler system sprits water into the air through a sprinkler head, forming tiny droplets that fall evenly to the ground. At the same time, the hanging spray system has strong adaptability to the terrain, and can flexibly adjust the position and Angle of the nozzle to meet the needs of different terrain and crops. The advantage of hanging spray irrigation is that it is fast, watering enough, and easy to water the soil. In summer, when the temperature is high, the hanging spray irrigation also has the effect of cooling and increasing humidity, which helps to improve the environment of the vineyard area. However, there are some disadvantages of hanging jet irrigation. Due to the large amount of water spraying, it is easy to cause soil erosion and nutrient loss, and cause certain damage to the soil structure.
The combination of drip irrigation and hanging spray: In practical applications, the two irrigation methods of drip irrigation and hanging spray are not isolated, but can be used in combination with each other. For vines with underdeveloped roots, drip irrigation can be used near the roots to ensure the precise supply of water and nutrients. For vines with relatively developed roots, hanging spraying can be used to meet their greater water needs and regulate the environment of the park. Through the combined use of drip irrigation and hanging spray, more accurate and efficient water and fertilizer management can be achieved to improve grape yield and quality
