Knotweed - who did not roll on the soft dense carpet of this grass, did not trample mercilessly! It is pleasant to lie down on the cool greenery, to feel the fragrant smell of fresh grass. The "miraculous" carpet returns strength and vitality.

Village yards covered with a thick cover of knotweed seem to have a peculiar microclimate - it seems to be easier to breathe here, and the air is cleaner, and it is not so hot on a sunny summer day.

In the temperate zone of Russia, 34 knotweed species are known. The most famous: amphibian, bird, crayfish necks, Scythian, ordinary, field, bindweed, sprawling, water pepper, etc.

Leaves of all types of knotweed are suitable for fresh salads. Nanais on the Amur and Orochi on the coast of the Sea of ​​Japan use raw water pepper as a seasoning for meat and fish dishes, as a substitute for pepper. Somewhat sour or sweetish in taste, the leaves of all types of knotweed (highlander) are used to make salads, soups, borscht, and cabbage soup.

When used for salads, a little spicy greens with a spicy aroma are added to them. Young leaves are also boiled and stewed until a homogeneous puree is obtained, which is used to stuff pies and vegetable dumplings. Finely chopped onions, hard-boiled eggs, salt, oil, and allspice are mixed into the puree. Serve on the table as a salad, side dish or seasoning for a variety of dishes.

In the Caucasus, in the central black earth regions, in Ukraine and the Far East, young knotweed greens, which can be harvested until late autumn, are used along with sorrel. Prepare salads, soup purees, side dishes. Dried fruits and leaves are ground in a mortar and the resulting flour is used as an addition to grain flour for home baking pancakes, donuts, and gingerbread.

Knotweed is called bird buckwheat. Its high feeding qualities attract all herbivores and humans. Knotweed greens are fed to songbirds.

The grass contains a large amount of protein compounds of calcium, potassium, phosphorus, zinc and silicon. Knotweed contains twice as much ascorbic acid as lemon juice. The juice also contains resins and tannins that aid digestion.

In Algeria, knotweed herb, dried in the shade, is successfully used to treat fever. In Austria it is used for nervous exhaustion and general weakness. Traditional medicine in many countries uses knotweed water infusions to lower blood pressure, stop internal bleeding, treat tuberculosis, as a diuretic for urolithiasis and liver stones.

Highlander bird. The value of the plant, the procurement of raw materials, the use in traditional medicine and cooking

Knotweed (highlander bird, bird buckwheat)

The velvet of green rural streets is woven from this grass, it has firmly taken possession of the highways, cattle passes, the banks of talkative rivers and even the clearings of the forest, trodden by paths. Knotweed thickets are captivating from spring to late autumn. In the grace of May, they shine with delicate emeralds, in summer the soft juicy network of branches paints the beaten lands in deep dark green tones, and in autumn, as it were, the knotweed turns iron, walks over it with ocher.

Sensitivity, responsiveness to the growing conditions of this herb are amazing. On poor soils, it wilts, twists like a wire, on fat soils it rises from the ground, closing into a dense herbage. And along the edges of old-arable fallows it will grow with long shoots so that even one plant will seem like a kulizhka. You pull out such an overgrown knotweed and marvel at how well-ordered and extensive it is. A long branched root will tell you that this plant will also adapt to dry soils, not without reason many species of knotweed, and there are 200 of them, are found in the subtropics, where a lack of moisture is constantly felt.

In the temperate climate zone, spores of the necks are more common than other mountaineers. It is an annual plant that renews every year. In early July, greenish-white flowers open on its stems, in the axils of oval leaves, in autumn the grass acquires black trihedral nuts. The fruits fall to the ground, and in the spring they, having thoroughly frozen before, sprout with small shiny blades.

The highlander does not accept any herbs as friends, except for some kind of crail - meadow geranium. Or he will reconcile himself with the "witch's rings": suddenly a bald patch appeared among the knotweed, and after the rain small mushrooms - meadow mushrooms - will slip through it. They say that mycorrhiza of fungi settles on the roots of this grass. By the way, meadow mushrooms are edible. In the roast, they will not yield to forest gifts, besides, they give a little bit of garlic and cherry pits.

As soon as they do not trample the grass-ant! In the villages, people walk along it every day, herds of cows and sheep drive; poultry will not bypass. Therefore, the people call the bird mountaineer toptun-grass. In the morning, with dew, cattle are driven out to graze on knotweed - the eatability of grass is excellent, in the afternoon pigs nibble it, chickens and geese peck. Sheep, returning from hearty pastures, still strive to grab grass-ants in the evening: tasty, nutritious.

Commercial animals - muskrat and ground squirrel, and they do not disdain to taste trampled herbs. Even upland game dismounts on it - black grouse, capercaillie, hazel grouse: they peck nuts. Songbirds in cages have not forgotten the knotweed, put the fruitlets - they will eat it. Its young stalks are also suitable for the table as fresh herbs.

Knotweed is a living treasure trove of protein and sugars. Found in it and such useful trace elements as calcium, phosphorus, zinc, silicon. And how rich it is in vitamins! Ascorbic acid - vitamin C grass-ant, for example, contains three times more than vaunted lemons. And although knotweed flowers do not give nectar, a wax coating is noticeable on the leaves and stems; its juice contains resins and tannins. A rich range of useful chemical compounds put forward the highlander bird in a number of valuable fodder grasses.

Hay made from pure knotweed is not inferior in nutritional value to legumes - alfalfa, clover, rank. True, they do not save it for future use: there are no pure thickets outside the villages. But mixed with other herbs, it ends up in fragrant haystacks.

Pharmacists did not ignore our weed. Dried with flowers in the shade, it is prescribed for many diseases: in Algeria - for fever, in Austria - for nervous exhaustion and weakness. In folk medicine in many countries, knotweed infusions lower blood pressure, stop bleeding, treat tuberculosis ...

Knotweed (highlander bird, bird buckwheat)

The list of benefits of this common herb is long; its extracts and infusions help to get rid of ailments of the liver, kidneys and stomach, and ointments - from some skin diseases. Once crushed fresh grass was applied to wounds and ulcers - it promotes healing. Knotweed is one of the medicinal plants of the international market. It is believed that its healing properties are due to the presence of tanoids.

The old Russian "Zelniki" prescribed bird mountaineer for ulibs and consumption. Original healers ordered them to soar their feet "from the tumor, when they trample" - hence the name of the herb "stomp".

It spreads in a green row, comparing potholes and tubercles, prostrate grass curls with knotted stems. If they trample on it, it will fall to the ground, if it is given free rein, it will stretch upwards. The modest demands of existence, the ineradicable thirst for growth and resettlement helped bird greek to occupy all inhabited continents.

Herds graze on knotweed thickets, diseases are expelled with its grass, and blue paint is prepared from the roots to match indigo. As it is - a good companion of man.

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

8051 IP cores are 15x faster 16.05.2013

Polish IP core developer DCD has released a new version of the 8051 core that runs 15 times faster than the original. The DP8051 is the fifth generation of 8051 IP cores in Digital Core Design's list of achievements. On the Dhrystone 2.1 test program, it showed a speed increase of 11,46 to 15,55 times, which was the result of using a pipelined RISC architecture with a speed of 300 MIPS.

The speed-optimized 8-bit software kernel is designed to work with both fast (usually on-chip) and slow (external) memory. A wide range of optional features and peripherals allows engineers to tailor the kernel to specific applications and/or hardware requirements. Furthermore, the kernel has been designed with particular attention to power consumption versus performance, using an advanced power management unit (PMU), as well as 2 to 15 interrupt sources, 4 interrupt levels, 2 data pointers, a USB device, an Ethernet controller, up to 4 timers/counters, 2 UARTs, 4 I/O ports, etc. Depending on the configuration, the designer can select a compare/capture module, watchdog timer, I2C bus master/slave controller, Quad SPI, floating point coprocessor, or integer coprocessor.

The result of DP8051 in Dhrystone 2.1 was 11,46 to 15,55 times faster than the original Intel 80C51 at the same frequency. To compare the speed of the kernels, the same C compiler with the same settings was used. This speed can be used for low power devices, where the core frequency can be 10 times lower than the original implementation, without performance degradation.

The DP8051, like other DCD 8051 IP cores, has built-in support for the DoCD hardware debugger, which provides the ability to debug the entire system on a chip (SoC). Unlike other on-chip debuggers, DoCD provides debugging without interfering with a running application. It also effectively saves designer time, thanks to hardware tracing called the Instructions Smart Trace buffer (IST). IST intercepts commands without interfering with their execution, and therefore intercepts the addresses of not all executable commands, but only those related to the beginning of the trace, conditional jumps and interrupts. This method not only saves time, but also reduces the size of the IST buffer and increases the trace history. The intercepted commands are read by the DoCD-debug program, parsed and presented to the user in the form of assembler code and corresponding C commands.
