The automatic lawn sprinkler system, also called lawn watering systems, improves the previous micro-irrigation system in the following three aspects:

Introduce new branch pipes to prevent the water outlet of the branch pipe from being invaded by crop roots and blocked by soil particles;

Laying under the branch pipe The impermeable polyethylene substrate prevents water loss due to deep leakage, especially the deep leakage of sandy soil;

Special installation equipment, which is equipped with a v-shaped machine tool, Laying substrates and pipes without destroying the natural structure of the soil.

Lawn Sprinkler Irrigation System

The automatic lawn watering system evolved from water drip irrigation. Because the irrigation efficiency of the grass sprinkler watering system can be as high as 90%, this technology is popular in global irrigation. Compared with other water irrigation systems, it has the advantages of low energy consumption, high water delivery efficiency, high irrigation efficiency, and high water use efficiency. advantage. However, its application has certain limitations:

High investment;

Poor irrigation uniformity;

Salinization problem;

Surface pipes and emitters have poor durability;

Complex technology;

Blocking problem

High automatic fertilizer for sprinkler system investment can be partially compensated by saving water and energy, especially after the investment recovery mechanism for water and energy distribution is established.

The lawn/grass sprinkler watering irrigation systems composition includes all the components of the traditional drip irrigation system: a pipe network composed of main pipes, and branch pipes, and lawn irrigation points are arranged along the branch pipes. The water delivery components below the pressure device and the filter with the fertilization box are buried in the ground 60-8cm deep. The new design of branch pipes and the laying of impervious substrates under each branch are its two major features.

How does Lawn Sprinkler Fertilizer System Work?

After installing in-ground lawn sprinkler watering systems, the water flow enters the spiral water supply lawn irrigation pipe through the hole on the inner wall of the main water delivery pipe. Due to the fins at the outlet of the pipe, the outgoing water cannot be inserted by the roots of the crop or blocked by soil particles. The outer diameter of the pipe is 25mm, and the inner diameter of the spiral water supply pipe is 1.8mm. The distance of the irrigator and the buried depth and spacing of branch pipes can be changed according to the farming requirements. The two standard pipes with different irrigator spacing are Type A: 33cm; or 66cm; or 99cm. Type b; 66cm; or 132cm.

To prevent deep leakage, especially in the sandy soil layer, an impervious v-shaped polyethylene liner is laid under each landscape drip line. The v-type substrate is 60cm wide and 0.06cm thick, and there is an interval of 2-5m between the substrates. In this way, on the one hand, excess water in the rainy season can penetrate the deep soil. On the other hand, the substrate retains rainwater, leaking water, and dissolved additives (such as fertilizers, herbicides, etc.) in the soil layer of the crop roots.

When laying water sprinklers for lawns and the substrate underneath, a v-shaped plow is used. This v-shaped plow can simultaneously lay the substrate and the pipeline to the required depth (30-70cm) below the ground surface. The plow is towed by a tractor. According to different soil conditions, its laying speed can reach 1-5 ha/day. Because there is no need to excavate the soil, the soil structure will not be damaged. If the plant spacing is constant, this equipment can also lay branch pipes and substrates on the already planted land.
