Before sowing, it is advisable to treat the seed material with certain types of radiation, which make it possible to activate biochemical processes in seeds and, consequently, increase germination, growth and maturation rates, and yields. The most interesting results were obtained during the treatment of seeds before sowing with an electrostatic field, gamma rays, solar spectrum light, etc. [1].

The same results as in the treatment of potatoes with an electric field can be obtained if an electric current is passed through the potato tubers before sowing. To do this, it is necessary to assemble a rectifier with an output voltage of 60 V. The electrical circuit of the rectifier is shown in Fig. 1.

The rectifier contains a step-down transformer T1, a capacitor C1 and a diode bridge VD11VD4. Capacitor C1 serves to limit the current in case of accidental shorting of the needle electrodes 1 and 2. The needle electrodes are used from disposable syringes that are connected to the rectifier using flexible wires.

Transformer T1 type TPP2355220050 or TPP2611220050, capacitor C1 type K73311 or MBGOO2.

For electric current treatment, a potato tuber is pierced on needle electrodes for seconds. As soon as foamy juice appears near the needle, the needles are turned off.

For processing directly in the area where there is no electrical network, you can use a 12 V battery with a voltage converter, the electrical circuit of which is shown in Fig. 2.

The converter is a generator of electrical signals on the transistor VT1. The generator frequency is determined by the inductance of section 223 of the transformer T1 and the capacitance of the capacitor C1. The oscillator frequency is approximately 300 kHz. The alternating voltage is increased by the winding 334 and is fed through the rectifier diode VD1 and the capacitor C2 to the needle electrode. The second needle is connected to the "+" source.

The adjustment of the converter is reduced only to the selection of the resistor R1 so that it works stably and the output voltage is 60 V. The T1 transformer is wound on a 2000NN ferrite ring with dimensions of 20x10x5 mm. Winding 114 contains 50 turns of HDPE220,25 mm with leads from the 3rd and 6th turns from the beginning of the winding.

The voltage converter is economical. If you use a small-sized battery, then it can be assembled in a convenient shell. This will allow the transducer to be used to apply an electric current to the stem of the plant. If, for example, to act on seedlings of tomatoes, when their growth is already 20 ... 30 cm, then you can increase the yield.

Of course, such results of applying electric current to plants require further verification. Their effectiveness or unsuitability can be determined by a wide range of amateur gardeners. This article pursues this goal.

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 Oxytocin in the fight against autism 05.02.2015 Scientists at the University of California found that oxytocin helps restore normal social behavior in mice showing signs of autism. The hormone oxytocin is a neuropeptide, a type of molecule that helps neurons in the brain communicate with each other. The biggest surprise of the new study is that the use of oxytocin results in a longer lasting benefit that continues into adolescence and into adulthood. According to scientists, oxytocin is a key mediator of social behavior in mammals, including humans - after the introduction of the hormone, the sociability of autistic mice increased and they began to spend more time interacting with other mice. The next stage of the study will be to identify the minimum doses of oxytocin suitable for effective therapy. The scientists hope that after extensive testing in mice is completed, experimental oxytocin treatment may be applicable to human patients as well.
