Main equipment for fruit tree drip irrigation and matters that should be paid attention to during operation. There are many ways to use water-saving irrigation for fruit trees, and drip irrigation is one of them. Drip irrigation for fruit trees has the advantages of saving water, not compacting the surface soil, not producing toxic substances, can be combined with pesticides and fertilization, and saves costs.
1. The main equipment for drip irrigation of fruit trees.
, water ingress. Water pumps, motors, electrical switches, etc. are used to form water inlet equipment to introduce water from rivers, lakes or reservoirs into tanks.
, water storage. Place aluminum tanks at higher places in the orchard to temporarily store water introduced by the water pump. The size of the bucket depends on the area of the orchard. There is a water outlet valve on the bottom side of the barrel to connect the plastic pipe.
, water delivery. A plastic pipe with a diameter of ~cm is laid between the rows in the orchard. One end is connected to the irrigation pipe, and the other end is connected to the dropper. This kind of water pipe can be buried in the soil or exposed on the soil surface.
, dripping water. Use a plastic dropper with a diameter of ~.cm, and lay it in a circle with the trunk of the fruit tree as the center. The distance between the first circle and the main trunk is cm, and the distance between the third circle and the second circle is cm. If the row spacing between fruit trees is wider, you can make another circle. Bury the plastic pipe ~cm deep under the soil. There are many small holes drilled on the pipe for water discharge. The diameter of the holes is about .cm, and the distance between the holes is ~cm. Cover with gravel near the water outlet to prevent mud from clogging the hole. Another method is to expose the dropper to the ground, but the dripping effect is not as good as the previous method.
2. Matters that should be paid attention to during operation.
Watering depends on the weather. When drip irrigation is needed depends on the type of cause and effect book. According to the data, drip irrigation can generally be carried out when the temperature is above ℃ and above the sky on non-rainy days.
, Irrigate according to soil moisture content. Different types of fruit trees have different requirements for soil water-holding capacity. For example, citrus requires the effective water-holding capacity in the field to be below %, while citrus requires the effective water-holding capacity in the field to be below %.
The drip irrigation garden should be covered. Drip irrigation is implemented, and many plastic pipes are laid in the orchard, which makes it inconvenient to loosen the soil for farming. At the same time, in order to avoid the hardening of the soil surface in the orchard due to rain, the garden must adopt biological coverage (i.e., interplanting, allowing native grass to grow in the garden, or covering it with organic matter, etc.).
, control the amount of fertilizer and medicine. The amount of fertilizer and medicine prepared for drip irrigation should be controlled according to the needs of each acre, and should not be too much. If additional urea is applied, if there are orange trees in each public area and .kg is used per plant, then kilograms of urea can be applied to each public area.
