Agricultural activities of awn seeds
The awn seeds indicate the maturity of summer crops such as wheat and the busiest planting season. At this time, agricultural production in most parts of China is in the busy season of "summer harvest, summer sowing and summer management".
Summer harvest is busy, because wheat is mature, in case of continuous rain or even hail disaster, wheat can not be harvested and threshed in time, resulting in lodging, grain dropping, unsuccessful germination and wheat field rot. We should seize every favorable opportunity to cut, transport and fight. Summer sowing is busy, because the growth period of summer sowing crops such as summer soybean and summer corn is limited. In order to ensure the harvest before autumn frost, it is necessary to sow early and plant early to obtain higher yield.
Management in summer is busy. Because of more and more rain and higher temperature after the solar term, spring crops such as cotton and spring corn have reached the peak of water demand, fertilizer demand and growth, which requires not only topdressing and water supply, but also weeding and disease prevention. Otherwise, diseases and insect pests, drought, waterlogging, hail and other disasters will occur at the same time or alternately, and the spring sowing crops will reduce production lightly, and the crops will be completely harvested.
The middle and lower reaches of the Yangtze River in China also entered the Huangmei season at this time. Meiyu days are generally characterized by rainy days, heavy rainfall, high temperature, less sunshine and sometimes low temperature. The annual rainfall in eastern China is about 1/3 (1/2 in some years), which is in the rainy season. The rainy season in the middle and lower reaches of the Yangtze River generally occurs after June. At this time, rice, cotton and other crops are flourishing and need more water.
The reason for the formation of Meiyu is that after winter, the intensity of cold air weakens and retreats northward, and the warm air in the south pushes northward accordingly, extending to the middle and lower reaches of the Yangtze River. But at this time, the cold air in the north still has a strong force, so the cold and warm air confronted each other in the Jianghuai Basin, forming a quasi-static front, causing rainy weather.
I. Overview of Vegetable Planting
Measures for the administration of greenhouse vegetables
(1) Increase ventilation and reduce the shed temperature. On sunny days, the shed door can be opened day and night, and the film on the east and west sides is ventilated; Cover the ventilated place with film in rainy days to prevent rainwater from leaking into the shed, and ventilate in time after rain.
(2) Continue to fertilize and water, remove diseased old leaves, prune and tie vines, and strengthen pest control.
(3) Clean up the garden in the shed in time after harvest. Clean the plants and branches of fruits and vegetables out of the shed and burn or pile them up.
4. Management measures for open-field vegetables.
There are many varieties of melons and vegetables cultivated in the open field, most of which are at the peak of harvest and vegetative growth. According to the cultivation technical requirements of different melon and vegetable varieties, fine cultivation management is carried out. Fruits and vegetables entering the harvest period should be topdressed every 7- 10 days, watered in time during drought, drained in time after rain, pruned, tendrils tied, old diseased leaves removed, and pest control strengthened.
3. Do a good job in the seedling cultivation of Kandelia candel and autumn pepper.
Two. Overview of fruit tree cultivation
1. Citrus fruit trees
Continue to pay special attention to fruit preservation, beware of abnormal high temperature fruit drop. Erase the summer shoots, and thin out some slender branches and over-dense branches. Strengthen the prevention and control of scale insects, whiteflies, mites, black spot disease and anthracnose, artificially kill longicorn beetles and scrape off eggs and larvae. Farming and weeding, shallow digging garden soil.
4. Myrica rubra
(1) Insect control and disease prevention: spraying 25% chlordimeform 800 times solution, 20% pyrethroid 3000 times thiophanate 800 times solution or carbendazim 1000 times solution at the beginning of the month to control brown spot, leaf curl moth and fruit fly. When the fruit is ripe, the adults of Drosophila melanogaster are trapped and killed to prevent fruit worms. Began to scrape the eggs and larvae of longicorn beetles at the bottom of the trunk.
(2) Branch management: young trees are sprouted and cored in summer, and dead branches are cut off.
3. grapes.
Continue to drain stagnant water and improve disease resistance. Continue to do a good job in the prevention and control of diseases and insect pests such as black pox, anthracnose, downy mildew and moths. Skillfully apply strong fruit fertilizer and topdressing outside the roots. Strengthen branch management.
4. Take a nap.
Take timely measures. Ditch cleaning and drainage. Fertilize after harvest. Trim. Control pests, such as yellow caterpillar and horned moth.
5. pear tree
Continue to control scab, black spot, ring rot, pear net stinkbug, aphids and moths. Continue bagging, which should be completed before the beginning of June. Continue to combine foliar fertilization when spraying. Topdressing with quick-acting fertilizer after rain will make fruits and branches strong. Strengthen ditching and drainage. Strengthen pruning in summer, and cut off long branches, overlapping branches, over-dense branches and dead branches.
peach
The middle and late maturing varieties continue to bag at the beginning of the month. Harvesting early-maturing varieties, and topdressing after harvesting; Look at the middle and late maturing varieties of topdressing trees. Summer pruning, mainly to tie the heart and prune long branches, needs to end in mid-June. Control moths, armyworms, scab and catch longicorn adults. Combined with pest control, topdressing outside the root. Ditching and drainage to improve disease resistance.
Mang seed health knowledge
"meditation"
Ear planting season is suitable for mood adjustment, so you can pay attention to mood adjustment, avoid excessive mood fluctuation and maintain inner stability. Go to bed early at night, get up early in the morning, and take a nap when you feel tired at noon. In this way, our bodies can keep in good condition and it is not easy to get angry.
In addition, in terms of dress, you can apply a layer of sunscreen when you go out to avoid excessive ultraviolet rays and protect your skin from sunburn. Change wet clothes in time after sweating, and don't wear dirty clothes, lest sweat and bacteria threaten your health. Take a rest when you sweat, and then take a shower when the sweat stops.
"Suffer hardships"
Generally, bitter food is delicious in summer, such as bitter gourd and lotus seeds. It is highly recommended that everyone eat it every day. This kind of food has the effect of clearing fire, which can well drive away the heat in the body and avoid dizziness, lethargy, bad temper, oral ulcer and other symptoms in summer.
"Drink acid"
Sour taste can astringe sweat, stop diarrhea and eliminate dampness. Some sour fruits, such as ebony, hawthorn, lemon, grape, strawberry, tomato, pineapple, mango and kiwi fruit, have the functions of dispelling summer heat, benefiting qi, promoting fluid production and quenching thirst. Because of its moderate tonic, it can also prevent sweating, gas consumption and yin injury.
You can also drink with fruit juice, but you can't use drinks instead of water. Soft drinks, cola and other beverages contain more saccharin and electrolytes, which will have adverse stimulation to the stomach and intestines, but will affect digestion and appetite.
"Eat porridge"
Li Shizhen, an ancient physician, suggested that porridge is a healthy diet in summer. Semen Phaseoli Radiati, Semen Nelumbinis, Folium Nelumbinis, Rhizoma Phragmitis, and Lentils can be added to japonica rice to cook porridge. After cooling, it can strengthen the spleen and stomach and dispel summer heat. In addition, barley and red bean porridge can clear away heat and strengthen the spleen, promote diuresis and nourish the liver, and melon and water chestnut porridge can benefit the stomach, quench thirst and relieve boredom, which are all good combinations.
"clean up"
"Cleanliness" does not mean eating only vegetarian dishes and fruits, nor is it the pursuit of absolute purity and vegetarianism. In fact, "nourishing" focuses on nourishing, but at the same time it has the function of clearing away heat and relieving summer heat, such as duck meat, which is characterized by mild temperature, clearing away heat, nourishing yin and stomach, invigorating spleen and tonifying deficiency, and promoting diuresis.
Moreover, Misgurnus anguillicaudatus has excellent characteristics of high protein and low fat, and is called "ginseng in water", which can play the role of tonifying the middle energizer, invigorating qi, detoxifying and beautifying the face.
Solar term characteristics of Miscanthus plants
1, rainfall
The Yangtze River is in the ear sowing season, and the Huanghuai Plain is about to enter the rainy season. If there is continuous rain, strong wind and hail before and after ear planting, and the wheat can't be harvested, threshed and stored in time, it will lead to the lodging, grain dropping, germination and mildew of the ear, "rotten wheat field" and destroy the crops in front of us.
After the awning, the monsoon rain belt in the southeast of South China is stable, which is the most rainy season in a year. The middle and lower reaches of the Yangtze River have entered the rainy season one after another, with more rainy days, more rainfall, less sunshine and sometimes lower temperatures.
In the awning season, rice, cotton and other crops grow vigorously and need a lot of water, and moderate plum rain is very beneficial to agricultural production; In the years when the plum rains are too late or too little or even "empty plum blossoms", crops will be threatened by drought. However, if the rainy days are too early, too many rainy days and too few long-term rainy days, it will also have a negative impact on agricultural production, especially if the rainfall is too concentrated or heavy rain will cause floods.
Southwest China has also entered the rainy season of the year since June. At this time, the hail weather in the southwest and western plateau areas began to increase.
2. Temperature
During this period, except for the Qinghai-Tibet Plateau and the northernmost part of Heilongjiang, people in most areas can generally feel the summer heat.
In June, whether in the south or the north, high temperature weather above 35℃ may occur, and high temperature weather above 40℃ may also occur in Huanghuai area and the eastern part of northwest China, but it is generally not a continuous high temperature. In China's southern provinces of Taiwan Province, Hainan, Fujian, Guangdong and Guangxi, the average temperature in June is around 28℃. If the air humidity is high before the thunderstorm, it is really stuffy and hot. Sometimes it is necessary to issue a high temperature forecast to the public to remind people to prevent heatstroke, air conditioning disease and acute gastroenteritis.
