Tip 1: Why are mowing in the city?
Every year in cities on lawns and yardterritories workers of housing and communal services and yard keepers mow the grass. Along roads, on urban areas, in parks and squares, this work is carried out by workers of green plantations of cities.
Some people are wondering whythe city needs to mow the grass. The answers here can be several: the grass is mowed by order and rules; for the prevention of tick-borne encephalitis and other diseases carried by ticks; because they pay well for this and, finally, because it is so beautiful.
Beveled grass according to law
If we consider the legal reason for the shorteninggrass in the summer, we need to remember that there is such a document as the "Rules for the creation, protection and maintenance of green spaces in the cities of the Russian Federation", approved by the order of the State Construction Committee of the Russian Federation No. 153. According to this document, the employees of the housing and communal services are responsible for caring for the greenery in the city: sowing, sowing, watering, fertilizing, cutting, plugging damaged areas, puncturing the ground for aeration, plant bushes, flowers. Lawns should be mowed when the grass is above 10 cm, and it is necessary to leave 3 -5 cm. The workers of the housing and communal services are obliged to mow the grass every 15-20 days. At the same time, the territory of forest parks and meadows does not fall under these rules. In fact, virtually no work on the care of green plantations, except mowing grass is not produced, either because of a lack of funds, or because the mowing - work is expensive in comparison with other care work.Bevel grass for human health and for aesthetics
The second important reason is thatIn many regions of Russia, iksodic ticks are common - carriers of encephalitis, borreliosis and other dangerous diseases. Female ticks are very active in spring and summer. Bites of ticks in yards, on playgrounds are quite frequent. A person seriously injured by a tick bite in the yard can file a lawsuit against housing and utilities workers and win the case if the grass has not been mowed in time.The mites bite not only people, but also pets that can bring them into the house with an unclimbed lawn.The third reason to mow grass is aesthetic. The site with a carefully mown dense grass looks much more attractive and better overgrown with weeds.
The city with well-groomed lawns, roadside green areas, with flowers and clipped shrubs seems to the guests more cozy and hospitable.Russian lawns are now, of course, far from English, but even in England it was different once. Years through a hundred and in Russia can appear the same neat and clean herbaceous plantations.
Tip 2: How to mow the grass
That the garden and garden plot hadattractive well-groomed appearance, it is necessary to regularly mow lawns and lawns, mow the weeds on the roadside. It is not difficult to do this if you buy a special tool - a trimmer.
Lawn in the garden
Culture of use of garden and cottage areasAt present, it is very different from what it was 10-15 years ago. With the abundance of products that appeared in our stores and supermarkets, there was no need to work throughout the summer on the beds to ensure the maximum supply of food for the winter. Now most gardeners use garden and garden areas as resting places, while plantings of vegetables and potatoes are given only a small part, and the rest of the area is occupied, as a rule, by fruit trees, bushes, planting flowers, and also lawns and lawns. Under Russian conditions, a full-fledged "English" lawn is not allowed by climatic conditions, but it is simply necessary to look after the grass that the garden plot has a well-groomed, attractive appearance.When buying a trimmer, be guided by its characteristics - the power, the size of the cutting blade, evaluate your financial capabilities and choose the golden mean between price and quality.
How can you mow the grass?
More recently, for mowing grassused hand braids, which are metal blades, fixed on wooden handles. The process of mowing was quite laborious, requiring a certain skill and skill. For example, the best time for mowing was the early morning, when the grass was damp from the dew, and in a dry weather it was problematic to mow the meadow qualitatively. It was also difficult to sharpen the braids, it also required special skills and skills. Fortunately, there was progress to help villagers and gardeners - a wide variety of garden machinery, including various lawn mowers and trimmers, appeared on sale. Each type of these tools has its pros and cons - for example, it is advisable to use the lawnmower with a large area and a flat surface of the lawn. It is intended for special mixtures of lawn grasses and their professional sowing, but with its help it will not be possible to mow the overgrown grass on mowing.The use of the trimmer ensures strict observance of safety procedures. Before using the tool, read the instructions carefully and strictly follow the safety precautions.
Ideal - trimmer
Much more democratic and simple inuse a special trimmer for mowing grass - on sale there are gasoline and electric options in different price categories. This option is ideal for small, not too flat areas, for mowing grass between bushes and trees. With its help, it is easy to mow grass for domestic animals. The cutting blade in the trimmer is replaced with a stern fishing line, which at a high speed of rotation mows and chop the grass. In more powerful models, in addition to the line, a cutting metal disk is provided, with which it is possible to mow down small shoots that form around the stone fruit bushes - plums and cherries. Despite the costs of purchasing equipment, gasoline and electricity, the use of the trimmer is very advantageous and convenient, it allows you to cope with the task without the special temporary and labor costs. To date, this is the most optimal option for mowing grass.Tip 3: Why in the city need green plantations
Green plantations, their location and necessaryarea, are necessarily taken into account when planning any kind of territories, especially residential and recreational areas. Trees, bushes and lawns in the urban planning carry out two important functions: sanitary and protective and decorative.
Sanitary-protective function of urban green plantations
It is difficult to overestimate the role of green spaces inecology of the urban environment. Thanks to them, dust and gas pollution of urban air is reduced by 60-70% - dust settles on grass and leaves, and the gas is filtered and processed into oxygen during photosynthesis. Even in the winter, when there are no foliage on the trees, they still prevent the spread of dust. Of course, planting green plantings, city services must take into account the dust-retarding properties of various tree and shrub species, which largely depend on the morphological structure of the leaves. To a greater extent, those rocks of the vegetation, on whose leaves there are villi, detain dust. In addition, the speed of growth affects the popularity of this or that breed used for greening streets. That's why most often on the streets of the city you can see poplars, elms, maples, plane trees and lilacs. Zagazovannost also adversely affects the vegetation. The most resistant to its impact are aspen, elm, poplar, Siberian apple, spruce. In addition to dust and gases, plants can also protect citizens not only from noise, but also from drafts and wind. With this function, shrubs and low trees with dense foliage are best handled. The wind speed can be reduced by 60% only due to the planting of green plantations with a width of 30 meters across the main streams of air circulating on city streets. In this case, the wind protection function does not decrease, even if there are passages and passages between plantings. As is known, plants release into the surrounding air environment phytoncides - substances that kill pathogenic and putrefactive bacteria. Especially with this are coniferous tree species, but deciduous trees - birch, poplar, bird cherry and oak - are also capable of disinfecting the air, reducing the bacteria content many times. In addition, vegetation increases the humidity of the air and reduces its temperature, which is especially valuable in the hot season.Decorative function of green plantations
Vegetation is an organic partThe urban landscape, giving it integrity and completeness. Due to the richness of colors and shapes that different breeds possess, changing their coloring depending on the season can decorate and revitalize any city landscapes. Using different types of trees in the greening of a particular area of the city can achieve their individualization and overcome the monotony of development. Individual parts of vegetation can play a planning role, organically blending into urban architectural ensembles. Especially invaluable is the role of green spaces in the organization of recreation and recreation zones. Parks and alleys are favorite places for recreation of citizens, giving them the opportunity to communicate with nature.Tip 4: Why the grass is green in spring
In spring it is very pleasant to walk around the younggreen grass! A bright sunny color and a rich green color of the grass lift the mood and make the walk interesting. Walk will become even more interesting, if you think about why the grass is green?
To explain this phenomenon, you must firstto understand how the color of objects is formed. Why are some objects black and others white? After all, the color of the light flux is initially white. But everything is quite simple and accessible for understanding.
As such, there is no color. Color is the result of the reflection of the light flux from a particular object. This reflected light perceives the human eye. Proceeding from this, it is very easy to understand the nature of the color of objects.
The surface of different physical bodies is capable ofreflect and absorb light rays in various ways. This is due to the microstructure of the surface and its chemical composition. The phenomenon is based precisely on the interaction of absorption and reflection.
If all colors are reflected - we get whiteColour. Therefore, white things do not get very hot in the sun. They reflect most of the light energy. Black things, on the contrary, get very hot. This means that they do not reflect energy, but absorb.
Accordingly, the grass is green becausethe ratio of reflected and absorbed rays forms a green glow. In this case, the cause of this is a substance that is called chlorophyll. It determines the course of the process of photosynthesis. The result of this process is the green color that our eye sees.
