Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.

The golden leaf Jingtian is a perennial herb of the sedum of the sedum. Plants 5 to 7 cm in height, stems growing, short internodes, strong branching ability, and good clustering. Leaves opposite, densely borne on stems, leaves rounded, golden yellow, bright, fleshy. The golden leaf landscape is naturally bright, cold-resistant, half-shade tolerant, bogey water, and is an excellent color leaf ground cover plant. The optimum temperature for growth is 15°C to 32°C, and it is not lower than 5°C in winter. In addition, the golden leaf does not resist trampling. The golden leaf Jingtian cultivation should select the well-drained sandy soil, avoid water, choose the sunny section when planting, apply about 1,000 kg of decomposed organic fertilizer and 20 kg of superphosphate per acre. Plant spacing 2020 cm, after planting irrigated. If you want to close the line in the short term, the spacing between the lines can be appropriately reduced. The breeding of gold leaf sedum is mostly based on ramets and cuttings. The ramets are dug in the early spring or fall and cut into several bundles and planted separately. The cuttings are carried out in the spring and autumn seasons. If there are cooling facilities such as full-light spraying, summer cuttings can also be used. Cut the shoots into small pieces of 3 to 5 centimeters when cutting and insert into the sand and pour enough water. The golden leaf Sedum has fewer diseases and pests, and the management is extensive. Usually, attention should be paid to flood prevention.
The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated Irrigation System
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
