Apples have a wide planting area in our country, and traditional irrigation methods, such as flood irrigation and furrow irrigation, have been gradually replaced by modern water-saving irrigation technologies. Drip irrigation, a water-saving irrigation technology suitable for apple trees in apple orchards.
Drip irrigation is an advanced irrigation technology that has emerged in the past thirty years. It uses a low-pressure pipeline system and drippers to drip evenly and slowly drop by drop of pressurized or self-pressured irrigation water into the root zone of fruit trees. In the soil, the root zone soil is often kept in the optimal moisture and aeration state for the growth of the fruit tree's root system, thereby promoting the growth and fruiting of the fruit tree. According to tests, drip irrigation in apple orchards is labor-saving, water-saving and energy-saving compared to surface irrigation. The apple leaf area is increased, the leaf thickness is increased, the leaf weight is increased, the thickness of the new shoots is increased, the total amount of the system is increased, and the absorbing roots are increased. Fruit yield and quality are significantly improved. Other fruit trees have achieved similar results using drip irrigation technology.
Header Settings
The header of the drip irrigation system mainly includes pressure equipment, control valves, filtration equipment, fertilization equipment, and measurement equipment. The required equipment is basically the same as that of the drip irrigation system. The difference is that the performance parameters of each equipment are required to be the same as those of the drip irrigation system. The systems are different, so careful selection should be made when planning and designing, especially the selection of filters, which is the key to drip irrigation systems. If the filter is improperly selected, the consequence may be that the dripper is clogged, or the filter is easily clogged, causing the system flow to be unable to meet the needs of irrigation, increasing the number of filter cleanings, and bringing a lot of inconvenience to the relationship. Therefore, the selection of filters must be based on the water quality of the water source and the requirements of the dripper for water quality treatment. Select an appropriate filter. If necessary, use a combination of different types of filters for multi-stage filtration.
Arrangement of trunk and branch pipes
The layout of trunk and branch pipes of the fruit tree drip irrigation system depends on the topographic water source, crop distribution and capillary arrangement. The layout should meet the requirements of convenient management and low engineering cost. Generally, when the water source is close to the irrigation area and the irrigation area is small, only branch pipes can be removed and no main pipes can be set up. The adjacent two-level pipes should be as perpendicular to each other as possible to minimize the pipe length and maximize the control area. In hilly and mountainous areas, main pipes are mostly arranged along ridges or along contour lines, while branch pipes are perpendicular to the contour lines and distribute water to capillaries on both sides. On flat ground, main and branch pipes should be controlled in both directions as much as possible, and lower-level pipes should be arranged on both sides to save pipe materials.
There are many options for the layout of the drip irrigation system in the same irrigation area. It should be determined through comprehensive analysis based on a comprehensive grasp of the crop topography and other information in the irrigation area, and the selection should be suitable for local production conditions and require less project investment and management. Convenient solution.
Arrangement of capillary tube and dripper
The dripper is manually installed on the capillary tube, so the arrangement of the dripper and capillary tube is carried out at the same time. The layout of drippers and capillary tubes depends on the crop type, planting method, soil type, dripper flow rate and dripper type. The convenience of construction and management must also be considered.
Fruit tree drip irrigation installation and layout
The spacing between trees and shrubs such as fruit trees and economic forests varies greatly, and the layout of the capillary tubes should be determined based on factors such as the size of the trees, the degree of planting regularity, and the dripper flow rate. Fruit economic forests can take the form of one pipe per row of trees arranged around the roots of the trees.
The hair tubes are arranged around the tree.
When the crown width and planting row spacing of fruit trees are large, the planting is irregular, and the root system is sparse, you can consider the arrangement of capillaries around the tree. The advantage of this arrangement is that the wetted area is nearly circular, and its wetted range It can be adjusted according to the size of the tree, and is also beneficial to the growth of the root system of the fruit tree in all directions. This arrangement is generally used when drip irrigation is installed in mature orchards.
