It's summer now, and it's time for busy farming. The following is my little knowledge about summer heat, I hope it will help you!
First, summer agriculture.
1, early rice harvesting and late rice transplanting
In China, in some areas, rice can only be planted for two seasons a year. Therefore, for these areas, timely harvesting of rice can not only reduce the harm of rain in summer solar terms, but also enable the rice to be sown in time in the next season.
According to the change of weather, arrange flexibly, cut more on sunny days and variety on cloudy days. We should finish planting for two nights before the end of July, and start in autumn at the latest.
2. Irrigation
The leaf area of cotton at flowering and bolling stage reaches the maximum in its life, which is the peak of water demand. It is best to require that the field soil moisture accounts for 70-80% of the field water capacity. Less than 60% is drought, which will lead to flowering and spitting, and must be irrigated immediately. It should be noted that it is not advisable to irrigate when the temperature is high at noon, so as to avoid excessive changes in soil temperature and aggravate the shedding of buds and bolls.
When soybeans bloom, it is also the time to store water, so the demand for water by soybeans at this time is very important.
3. Drought tolerance
In hot summer, water evaporates very quickly, especially in the middle and lower reaches of the Yangtze River during the summer drought period, and the demand for water by vigorously growing crops is more urgent. It's really "summer rain is like silver and summer rain is like gold".
Second, summer farming poems
The summer temperature is in the middle, and the annual temperature is higher.
When the flood occurs, the task of flood control and drainage is urgent.
Spring and summer crops should be reasonable, and pest control should not be delayed.
Corn is artificially pollinated, and the upper and lower grains on the ear axis are aligned.
Cotton management must pay close attention to, repair and control pests, and often hoe the ground.
The roof will be dismantled in stages, no later than the end of this month.
It is a good time to accumulate fertilizer and make green manure.
Continue afforestation in rainy season, and plant scattered plots together.
Early-maturing apples are picked, and it's time for the red locust tree to harvest.
High temperature can prevent heatstroke of livestock and treat sunburn (disease) and rotten hoof (disease).
Fish lacking oxygen flooded the pond, and their heads floated before sunrise.
When alum water is sprayed with salt water, the fish in the whole pond will be quiet.
Third, heat preservation
"Great summer, great summer, steaming on the top and cooking on the bottom", the arrival of the great summer solar term means that most parts of China enter summer, which is also the hottest season of the year. The weather is hot, people sweat a lot and consume a lot, so Chinese medicine health care emphasizes that we should pay attention to supplementing physical strength, reducing fever and preventing heatstroke in summer. There is a custom of eating three treasures-Monopterus albus, honey lotus root and mung bean sprouts.
Eat "bitter" and taste "sour" to stay healthy.
Bitter foods are mostly vegetables and wild vegetables, such as lettuce, lettuce, celery, fennel, coriander, bitter gourd, radish leaves, moss and so on. Eating bitter food in midsummer can not only clear people's inner troubles, refresh their minds, but also stimulate appetite, strengthen the spleen and benefit the stomach. But in moderation, or you'll hurt your stomach.
People sweat a lot and lose body fluids easily. Sour fruits such as tomato, lemon, strawberry, dark plum, grape, hawthorn, pineapple, mango and kiwi fruit can stop sweating, relieve diarrhea, eliminate dampness, promote fluid production to quench thirst, strengthen stomach and promote digestion, and stimulate appetite. People like to eat cold food in hot summer. If vinegar is added to dishes, acetic acid can sterilize and prevent gastrointestinal diseases.
Mental health preservation method
In Laozi's Tao Te Ching: "The old road is big, big, big, and the National People's Congress. There are four in the domain, and people live in one. " Xunzi further pointed out: "Fire and water are alive but not alive, plants are alive but ignorant, animals are conscious but unintentional, and people are conscious and intentional, so it is the most expensive in the world."
"On Su Wenquan's Insurance" also said: "Everything is ready, not expensive." The Taoist classic "Taiping Jing" also repeatedly talks about the idea of attaching importance to life and health, enjoying life and hating death. It is pointed out that "everyone can have a life between heaven and earth, and cannot be reborn", so we should cherish life. Therefore, the theory of "self-love and self-care" is put forward, that is, "if people want to live a long life, they should know how to love themselves and care for themselves, but they can be harmless." It shows that only through self-care and active exercise can we live a long life.
Chinese medicine advocates a word "ping", that is, under no circumstances can there be excessive behavior. When you are overjoyed, you will be sad. If you are heartbroken, you will be distracted, unable to concentrate, and even insane. Therefore, it is also the same reason that summer health care focuses on the word "peace of mind".
It is advisable to exercise less and rest.
As the saying goes, "the heat is at three volts." The heat is the beginning of the dog days. According to the theory of traditional Chinese medicine, summer heat is the time when the human body is full of yang, which is also called "Weiyang" or "Wei Qi" in traditional Chinese medicine. The word "Wei" here means guarding and defending, that is to say, the sun's spirit, like the guardian of the human body, is responsible for resisting all external evils and maintaining the safety of the human body. As long as the yang is strong, anyone will be immune to all diseases.
In the hot summer, when the sun shines and the geothermal transpiration, it is the time when the human body is full of yang activity, and the health care should also focus on yang to adapt to the seasonal changes. When people are working and living, they should pay attention to the combination of work and rest to protect the yang of the human body. At this time, it is best to adhere to the principle of "less movement and more quiet". It's best to go to nature, take a walk in the mountains, relax bamboo, read books and learn Chinese characters in a quiet room, drink tea and recite poems, and enjoy the cool scenery. Exercise is best in the morning and evening, and morning exercise should not be too early, so as not to affect sleep.
Fourth, what to eat in the heat?
1, watermelon
Watermelon can not only clear away heat and detoxify, but also relieve boredom and thirst, and promote diuresis and digestion. Therefore, people must eat some watermelons, especially those who work outdoors or indoors in high temperature. Watermelon juice is also rich in nutrients needed by human body, such as sucrose, glucose, fructose, citrulline, propionic acid, alanine, glutamic acid, arginine, phosphoric acid, malic acid, salts, carotene, vitamin C and so on.
2. Mung bean soup
Mung bean: After work and labor, drinking a bowl of mung bean soup will make you feel refreshed, thirsty and relaxed. This is because mung beans have the effects of clearing away heat and relieving summer heat, quenching thirst and diuresis.
3. Cucumber
"Seeking Truth from Materia Medica" mentioned that cucumber is "sweet in taste, cold in nature, and can clear away heat and benefit water". Therefore, it is good to eat more cucumbers in hot summer. The water content of cucumber is 96%~98%, which is the highest among vegetables. The cellulose it contains is very delicate, which has a certain effect on promoting the excretion of rotten food in the intestine and lowering cholesterol.
4.eggplant
"Compendium of Materia Medica" says that "eggplant is sweet, cold and non-toxic. Indications are cold and heat, strain of five internal organs and plague. Eating eggplant can disperse blood and relieve pain, remove dysentery and diuresis, reduce swelling and moisten intestines. "
The Compendium of Medical Forests says that eggplant is "wide in the middle, dispersing blood and stopping diarrhea". Modern medical research shows that the rich vitamin P in eggplant can enhance the adhesion between cells, prevent and treat microvascular embrittlement bleeding and promote wound healing. Therefore, eating eggplant often can prevent and treat diseases such as cerebral hemorrhage, hypertension and arteriosclerosis, and also has a certain therapeutic effect on chronic gastritis.
5, vitamin supplements
Summer solar terms, high temperature and high humidity, such weather will cause people's autonomic nervous dysfunction, and then there will be neurasthenia symptoms such as general weakness, palpitation, sweating, insomnia and dreaminess. Therefore, Li Nuo, a senior nutrition and health care technician of Keweijian Health Management Co., Ltd., suggested that people should take vitamin C and vitamin B complex appropriately to help regulate autonomic nerve function and eliminate symptoms.
Vitamin B 1, B2, nicotinic acid supplementation: In summer, drinking more water and sweating more easily lead to the loss of vitamin B group. Vitamin B 1 is responsible for converting carbohydrates in food into glucose and providing energy for the operation of the brain and nervous system. Without it, the energy in the body is insufficient and people will be listless.
Vitamin B2 is also responsible for converting heat energy, which can help protein, carbohydrates and fats release energy. Foods containing vitamin B include beans, brown rice and milk.
Nicotinic acid, also known as vitamin B3, is responsible for carbohydrate metabolism together with vitamins B 1 and B2, and is also a good brother of B family, providing energy for the body. Without nicotinic acid, people will be anxious and fidgety.
Vitamin C supplement: In hot weather, a lot of sweating leads to the rapid loss of water-soluble vitamins, especially vitamin C-the demand in summer will be more than that in winter, so when you feel tired in midsummer, you should supplement vitamin C to relieve fatigue.
6.wax gourd
It has a good effect of clearing away heat and relieving summer heat. In summer, eat more melon to quench thirst, relieve summer heat and diuresis. Because it is a diuretic and contains very little sodium, it is a good product to reduce swelling of chronic nephritis edema, malnutrition edema and pregnant women edema. It contains a variety of vitamins and trace elements necessary for human body, which can regulate the metabolic balance of human body.
