The growth and reproduction of pigs are inseparable from water. Water is the source of life. In the feeding process of live pigs, special attention should be paid to the farm; water pressure, water quality, and water temperature. Only suitable water pressure, water quality, and water temperature can ensure the healthy growth of live pigs. Improper water pressure and water temperature can easily cause pigs to have insufficient drinking water. Affecting the growth of pigs and the amount of milk produced by sows, severe water shortages can even lead to the occurrence of diseases in pigs. Poor water quality can easily cause pigs to become infected. Therefore, attention must be paid to pig farms in the production of pigs; , water quality and temperature, especially in summer. Key technical measures: 1. Control the water pressure of the drinking fountain in the pig house The proper water pressure of the drinking fountain is the basis for ensuring that the pig can drink enough water. The first is that the water pressure is too high and it is difficult to drown the pigs, and the pigs do not dare to drink for a long time, resulting in insufficient drinking water, which is likely to cause waste of water. The low water pressure may also cause pigs to have insufficient drinking water, especially piglets. The height of the water tower or tank and the height of the drinking fountain can all affect the water pressure. Followed by the unreasonable level of drinking fountains, a lot of pigs drinking fountains a height, farmers think that such a big pig can drink, pig can also drink. Difficulties in drinking water can also lead to insufficient drinking water and decreased or reduced feed intake. 2. Quality of water The quality of water directly affects the animal's water consumption, feed consumption, health, and production levels. The quality of water is not easy to distinguish from the eye. Excessive heavy metals, pesticide residues in water, and pathogenic microorganisms such as bacteria and viruses are all invisible to the naked eye. Only when the pigs are sick can they know. The iron in the water will facilitate the growth of bacteria that can produce a special taste, and it will easily clog the water pipe. Therefore, water quality should be checked frequently. In the summer, the water is prone to magnetic pathogenic microorganisms, and the water tower and water tank should be cleaned regularly and water-disinfectant should be added to the water with a suitable concentration of disinfectant. 3. Water Temperature The temperature of drinking water should be maintained at 10-15°C. When the temperature is too low, the digestive enzymes in the body cannot play a role, and the feed can not be digested to cause diarrhea; when the water temperature is too high, gastric juice cannot be easily secreted and the gastric juice also affects digestion and absorption. In a hot barn, when the water temperature is 11°C, the daily drinking amount is 10.5 liters; when the water temperature is 30°C. Drinking water is only 0.6 liters. High ambient temperatures increase water requirements and are more pronounced in sows and finishing pigs. The temperature is based on 20°C. For each increase of one degree, the sow needs to increase drinking water by 0.2 liters per day. The increase in the amount of drinking water leads to an increase in the amount of water discharged from the urine, which is an effective way to reduce body temperature. Environmental water temperature increases from 12-16°C to 30-35°C. The consumption of water is increased by 50%. Ensuring adequate drinking water can increase piglet weight by 1 kg per head at weaning for 24 days and shorten the time from sow weaning to re-breeding by 1 day. . Therefore, suitable water temperature is one of the important conditions for ensuring that pigs can drink enough water. If the water temperature is too high in summer, it will seriously affect the amount of water the pig drinks. Therefore, the water system introduced from the water tower to the piggery should be insulated and protected from heat, and the water pipes must not be exposed to the sun in the summer. Otherwise, it will cause the water temperature in the water pipe to rise and affect the pig's drinking water. 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 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.
