Summer is hot and humid, and various diseases are easy to come by. Diet experts recommend eating the following four types of vegetables, which will greatly benefit human health. 1. Eat more melon vegetables with high moisture content: In summer, the temperature is high, and the human body loses more water than other seasons and needs to replenish moisture in a timely manner. The moisture content of wax gourd ranks highest among all dishes, up to 96%, followed by cucumber, gourd, gourd, chayote, pumpkin, bitter gourd, watermelon and so on. This means that eating 500 grams of vegetables is equivalent to drinking 450 milliliters of high-quality water. In addition, all melon vegetables have the characteristics of high potassium and low sodium, which has the effect of lowering blood pressure and protecting blood vessels. 2, eat more heat to cool the cold vegetables: the most important factor influencing the human body in the summer is Shushi poison. After Shushi invades the human body, it will lead to the opening of the pores, excessive sweating, resulting in qi deficiency, but also cause spleen and stomach dysfunction, food indigestion. Eating cold vegetables is good for thirst, eliminate irritability, relieve heat, remove heat, and detoxify. The cool vegetables marketed in summer include bitter gourd, gourd gourd, cucumber, melon, watermelon, melon, tomato, eggplant, celery, chrysanthemum brain, lettuce, and asparagus. 3, eat more summer diet toxins bitterness of the fire: scientific research found that bitter foods contain amino acids, vitamins, alkaloids, hydrazine, trace elements, with anti-bacterial anti-inflammatory, antipyretic heatstroke, refreshing, eliminate fatigue And other medical and health functions. Modern nutritionists believe that bitter foods can promote the secretion of gastric acid, increase the concentration of gastric acid, and increase appetite. Common bitter vegetables are bitter gourd, bitter herbs, dandelions, lotus leaves and so on. 4, eat more anti-inflammatory and bactericidal vegetables: high temperatures in the summer, the rapid growth of pathogens, is the human disease, especially the season of intestinal infectious diseases. At this time, eat more "sterilized" vegetables to prevent diseases. Such vegetables include: garlic, onion, leeks, green onions, green onions, garlic, garlic, etc. These onion and garlic vegetables are rich in plant broad-spectrum fungicides, which can kill and inhibit all kinds of cocci, bacilli, fungi and viruses. Among them, the most prominent role is garlic. Recent studies have found that the active ingredient of garlic is mainly allicin. Since the garlic enzyme in garlic loses its activity when exposed to heat, in order to give full play to the sterilization and disease prevention functions of garlic, it is best to eat raw food. 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.
