How does the installation spacing of adjustable micro sprinklers affect the irrigation effect
In the application of modern agricultural irrigation technology, adjustable micro sprinklers have gradually become the mainstream choice for farmland irrigation due to their excellent water-saving performance, high efficiency and flexibility. However, the setting of the installation spacing has a great impact on the irrigation effect in practical applications.
The installation spacing of adjustable micro sprinklers is defined as the distance between two adjacent sprinklers. This key parameter directly affects the uniformity of irrigation water distribution, crop growth conditions and water resource utilization efficiency. Reasonable installation spacing can ensure that irrigation water covers the crop area in the best way, thereby achieving the goal of water saving and increasing production.
For low crops, such as vegetables and herbaceous flowers, a smaller installation spacing is recommended. This is because low crops have dense leaves and relatively shallow roots, and they urgently need more intensive water distribution to meet their growth needs. If the installation spacing is too large, the irrigation water may form larger water droplets or water columns, resulting in insufficient water supply in some areas, while other areas may be over-wet. This uneven water distribution will not only inhibit the normal growth of crops, but may even cause diseases.
For tall crops, such as trees and arbor, it is particularly important to appropriately increase the installation spacing of micro sprinklers. The crowns and branches of tall crops will block the direct fall of irrigation water. If the installation spacing is too small, the irrigation water may be intercepted by the crown, resulting in unsatisfactory irrigation effect. In addition, the root system of tall crops is usually deep and requires a large amount of water. Therefore, appropriately increasing the installation spacing can ensure that the irrigation water evenly covers the root area and reduce the canopy's blocking of water.
In actual operation, the choice of installation spacing is not fixed. It should be considered comprehensively based on a variety of factors such as crop type, growth stage, irrigation needs and soil conditions. For example, in the early stage of crop growth, the root system has not yet fully developed, and more intensive water distribution is required to ensure the normal growth of crops; in the later stage of growth, the root system is relatively developed, and the installation spacing can be appropriately increased to reduce the irrigation intensity and reduce the waste of water resources.
Irrigation demand is also an important factor affecting the selection of installation spacing. For crops with large water requirements, such as rice and wheat, the installation spacing should be appropriately reduced to increase the irrigation intensity and frequency to ensure that the crops have sufficient water supply. Relatively speaking, for crops with smaller water requirements, such as certain vegetables and flowers, the installation spacing can be appropriately increased to reduce irrigation intensity and thus reduce the waste of water resources.
