If your summer cottage has a garden and a vegetable garden, then you willy-nilly fall into slavery to him, if not for the rest of your life, then for the entire spring-summer-autumn season. Plantings require loosening, weeding, grafting, fertilizing, watering ... In a word, every Friday the gardener hurries to his six acres. And in a particularly hot summer, watering once a week is indispensable: the sun quickly dries up the water, leaving green friends without life-giving moisture.
However, there are methods of intrasoil metered irrigation, which allow, with a minimum amount of water, to deliver precious water directly to the roots, ensuring a continuous supply of moisture to a wide variety of plants - flowers, bushes and trees. With the judicious use of our technique, it is possible to leave the area unattended for three to four weeks.
First you need to choose suitable containers for water - plastic cans or bottles of carbonated drinks are suitable here. In the lower part of each, near the bottom, you need to make several tiny holes - the easiest way is to melt them with a red-hot needle. The diameter of the holes is selected empirically so that water flows out of the canister in two to three days.
Next, the containers are buried in the ground near the plant, and their lower part, where the holes are located, is wrapped with burlap or fiberglass, and a nylon or elastic stocking is pulled over it - this will prevent the soil from silting up the smallest holes in the plastic. That, in fact, is all. It remains only to pour water into the containers - and you can be calm for the plants: they will have enough moisture for a week.
The watering device can be upgraded - it can be supplemented with the so-called "drinking bowl" from a plastic bottle filled with water, fixed above the canister. As soon as the water level in the canister decreases, the bottle restores the status quo and brings the water level in the canister back to its previous level.
The simplest devices for metered underground irrigation using plastic canisters, soda bottles and polystyrene pipes

However, all these devices are unlikely to be able to let you go on another monthly vacation. For such a long break in watering, a more complex watering machine will be required. But this complexity will not become an obstacle for any home craftsman.
Such a machine for metered underground irrigation will be able to provide water for not one, but a whole group of plants or even all plants on the site. If the plot has a centralized water supply, it will be able to work without your participation throughout the summer season, saving you from this laborious work. You can do without running water by installing a water tank on the site - an old bath or one or two barrels; with such a supply of water, the machine will work for a month.
The basis of the watering machine is a float chamber buried in the soil, consisting of any suitable container - a cut plastic or aluminum canister, a pan. can, etc. - and a conventional float valve fixed in it from a flush toilet tank. The container is equipped with an outlet pipe, which is connected with a rubber hose to dosing devices (as in the first version - small plastic canisters), soda bottles or (for watering fruit trees) plastic pipes used when laying an electric cable.
Excellent results are obtained by using a plastic hose produced for watering the garden as a dispenser. It is only necessary to melt small holes in it with a red-hot needle, bury it to the depth of the bayonet of a shovel in the middle of the garden bed or rings around the berry bushes and connect it to the float chamber. The free end of the hose must be plugged.
It is enough to open the water supply valve to the float chamber - and water will fill it until a certain level is established in it. As water soaks into the soil, the level will decrease, the float valve will open - and the water level will be restored.

Machine for thinning flowers in gardens
02.05.2024
In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers.

Advanced Infrared Microscope
02.05.2024
Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>
Air trap for insects
01.05.2024
Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
| Random news from the Archive Graphene laser for photonic microcircuits
07.06.2013
An international team of researchers from the UK, Greece and Japan has found a new use for graphene. Based on this material, it was possible to create an infrared pulsed laser, and, according to scientists, such lasers can also generate ordinary light pulses.
Graphene is distinguished by the absence of a band gap, that is, its electrons can be in a state with any energy level, unlike insulators or semiconductors, which have a certain minimum distance between the ground state and the state following it in energy. Due to the absence of a band gap, graphene can absorb even quanta with not very high energy and thus temporarily block infrared laser radiation.
When graphene is exposed to infrared radiation, the material at a certain moment (in the experiments of physicists this happened in less than a nanosecond) sharply changes its optical properties and becomes transparent. According to scientists, the implementation of such an effect directly inside the ytterbium-glass laser makes it possible to control its operation: the laser emits only when the graphene film placed inside its resonator becomes sufficiently transparent. After the graphene releases a light pulse to the outside, it begins to absorb radiation again and everything repeats again, with a frequency of about 1,6 GHz.
Calculations show that a similar scheme can be successfully used to generate pulses with any other wavelength, both in the near infrared and in the visible range. In other words, it is theoretically possible to make pulsed lasers of various colors based on graphene, and the material does not need to be subjected to additional processing. The authors of the new work consider the heat resistance of the material to be another advantage of graphene: many other substances with similar properties quickly burn out under intense irradiation.
