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.

Based on the prevention and control of agriculture, it can be used to deepen and dig deeper, and the use of fully cooked manure and cake fertilizers can reduce the hazards of a variety of underground pests. Shed-packed vegetables combine high-temperature stuffy sheds in the summer to eliminate field larvae and reduce the population density. After the harvest of the previous season crops, the field stubbles were cleared in time to remove the weeds in the fields and the surrounding areas and reduce the occurrence of pests spawning and concealment. After harvesting, the fields were filled with water and kept in 5 cm water for 3 days. The soil pests were suffocated by irrigation.
According to local conditions, physical pests can be used to control insecticides, and sweet and sour sauces placed in pots can be used to trap and kill adult insects. It is also possible to seduce bran and bean cakes with saute.
Timely medication chemical control (1) seed dressing. 40% phoxim EC or 48% chlorpyrifos EC can be used. The proportion of medicine, water and seeds is 1:30～40:400～500. The seeds on the plastic cloth are evenly sprayed, mixed while spraying and mixed. Bored 3 hours, during which 1 or 2 times, seeds can be sown after drying. (2) Spread poisonous soil. Prevention of earthworms, cockroaches, etc., with 3% phoxim granules 5 kg per mu or 15% chlorpyrifos granules 3 kg. Prevention of yellow stripe jumps, with 1% of bifenbide granules per acre granules 3 to 4 kg, mixed with 15 to 20 kilograms of soil made of toxic soil, along the ridges applied near the roots of vegetables. (3) Root irrigation. When the underground pests are found to be harmful during the seedling stage, 90% crystals of trichlorfon 800 to 1000 times or 40% phoxim 500 to 800 times can be used to water the roots. The control root can use 0.5% matrine water 500 to 800 times liquid along the rhizosphere watering. (4) Ground spray. In the period of the migration of the yellow-trickle-jumping adults (radish and other true leaf flat periods), it is possible to use 2.5% deltamethrin EC or 5% chlorfluazuron EC 2000 times for spraying. Note alternating medications, each drug can only be used once every growing season.
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.
The main pests in vegetable fields are maggots, cockroaches, yellow song strips, root fleas, etc., which are mainly harmful to autumn root vegetables, onions and garlic vegetables, resulting in vegetables lacking seedlings and ridges, root and stem lesions and plant yellowing, etc. Affecting the yield and quality of vegetables, comprehensive measures should be taken to prevent and control them.
