Potatoes have less fat, and their calories are much lower than their staple foods. They are also rich in dietary fiber and are good for intestinal peristalsis. Residents of our country should increase the intake of potatoes. It is recommended that 50 to 100 grams each time, 5 times a week.
Eat Potatoes - Preventing Emotional Heat Stroke
When the summer heat is very hot, people can easily get irritated and have abnormal behaviors such as upset, listlessness, disorganized thinking, loss of appetite, anxiety and anxiety. This is called "emotional heat stroke."
"Emotional heat stroke" is harmful to health and physical and mental health in the summer, especially in the elderly and frail. Emotional disorders can cause them to suffer from myocardial ischemia, abnormal heart rhythm and high blood pressure, and even cause sudden death. Prevention of "emotional heat stroke" may wish to eat some potatoes.
The potatoes are potato names. In France, potatoes are called "underground apples." Potatoes contain vitamin C and have high calories. People with “emotional heat stroke†are the most vulnerable to depression, frustration, anxiety and other negative emotions. The potato helps you to solve the problem. It can affect people’s emotions because it contains minerals and nutrients that can act on The human body improves mental status. The potato can help you to supplement vitamins A and C. It can also replace the pH imbalance caused by eating too much meat and provide you with nutrients.
Eat purple sweet potato - protect blood vessels against allergies
Prevention of cardiovascular and cerebrovascular diseases in the summer and issues such as allergy prevention are topics that many readers and friends have to face. From the perspective of diet, you may wish to eat some purple sweet potatoes. Purple sweet potato is rich in iron, selenium and anthocyanins. Selenium and iron are essential elements in the body's anti-fatigue, anti-aging, and blood-supplementing activities. In particular, selenium is known as the “anti-cancer king†and is easily absorbed by the body. Anthocyanins are powerful antioxidants that protect the body from harmful substances called free radicals. Anthocyanins also increase blood vessel elasticity, improve circulation, inhibit inflammation and allergies, and improve joint flexibility.
Eat yam potato - moisturize the skin and spleen and stomach
In summer, people often experience symptoms of generalized weakness, loss of appetite, proneness to sweating, and lethargy due to rising temperatures. Therefore, a reasonable diet is very important. This season, you should eat more foods that are hot and dry, like yam. The mountain medicinal name, yam potato, which contains an important nutrient component, is yam soap, which is known as natural DHEA. DHEA contains a variety of hormonal substances, which are called the mother of hormones. It can promote the synthesis of endocrine hormones, promote the metabolism of skin epidermal cells, enhance the skin's moisturizing function, and also help improve physical fitness.
Summer diet, partial cold can easily lead to gastrointestinal discomfort, eating yams can also help. According to the "Compendium of Materia Medica" records, yam is warm, sweet, non-toxic, can be spleen and stomach, benefit lung and kidney, the amount of food can help digestion, detoxification hangover, resolve accumulation.
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.
