Description

one

This invention relates to agricultural scaffold production and is intended. to increase the quantity and quality of farming, on the floor.

There is a known method for controlling plant growth by altering the environmental characteristics to achieve maximum photosynthesis I.

The disadvantage of this method is its use only in the ground soil, as it is not possible to support external factors in field conditions.

There is also known a method for controlling the growth of plants by changing the atmospheric-electric current, implemented, for example, in a device containing a metal grid suspended above the experimental field 2.

This method, however, does not take into account changes in the complex of external environmental factors; as well as the phases of growth and development of plants, which prevents obtaining maximum yields and does not allow to regulate the quality of the crop.

The aim of the invention is to increase the yield and control the quality of the crop. "

This is achieved by controlling the nature of the metabolism of plants depending on a complex of external environmental factors, in accordance with which they control the magnitude and sign of the electromagnetic field. In addition, a plant genotype that is most susceptible to changes in electromagnetic and electric fields is selected.

Example. Wheat cultivation np rainfed land x.

When growing plants on the floor of the farm, there are conditions when one of the elements of a complex of crop factors finds itself in an undesirable state and requires such management of plant growth at its particular developmental phase to ensure yield and, if possible, control its quality.

Wheat is growing, a critical period of tillering stage sets in, and rain and watering have been delayed for a short-term forecast for a week or over-wet. Fia

That phase of wheat growth requires its development to be prevented so that there are no tillers on dry soil or on overmoistened ones. This can be done by suppressing the soil and plant microlor with pulsed electromagnetic fields by artificially creating a negative gradient of the electric field of the earth near the plants, for example by applying adjustable voltage to the grid suspended above the field with plants, or by spraying the plants with negative aerosols. Changing the sign of the natural electromagnetic field or the oTcytCTBHe gradient of the natural electromagnetic field when spraying plants, for example, after 30 minutes with aerosol, stops the photosynthesis and slows down the development of plants at this stage until the soil reaches the optimum value. After that, on the contrary, it is necessary to speed up the stage of plant development and, with a favorable complex of crop factors, achieve the maximum development of plant metabolism, since at this phase of wheat development it formed}) uGS. crop quality.

H3Bie; tHO that the course of transpiration of plants depends both on the features of the application itself, fak k from its organizations. It has also been established that the processes in the cell depend not only on chemical transformations, but on joining, splitting off and moving atoms in the primary structure of BiHojiHM poB molecules. An important role in the nature of a particular reaction is played by the configuration of the chains, the spatial arrangement of the parts. Come, fasten these st. The arms are weak and can easily be disrupted by the outside. by the influence of a drive, for example, to reduce or mustache: the catalytic activity of enzymes, and thus to control the course of plant metabolism. Therefore, using on each phase of plant development already known factors that exist in nature, in particular, electromagnetic effects, allows controlling the metabolism of plants while controlling efficiency; such an effect is provided by feedback.

Famous photosynthesis and gas exchange sensors of plants can be used as sensors for the metabolism of plants .... From the agrotechnology of each particular plant, it is known that, for example, at this time, at this stage of development, the plant needs fertilizing with fertilizers and microelements. However, their introduction into the soil does not yet ensure their delivery to plants due to the weak solubility or absence of the necessary microorganisms in the soil. Therefore, the plant needs

fertilizer and trace elements, they are in the soil. But in a form that is inconvenient for development, and therefore the plants are starving.

For plants at each phase of their growth

and the development for a specific time of the turning point of the control action of the electromagnetic field is determined by the sensors controlling the complex of crop factors, and instead of part of the sensors can be used and agronomic experience, and

feedback from this exposure is also monitored by sensors for the metabolism of plants. The presence of feedback pos. choose the most effective and the magnitude of the electromagnetic effect

not plants, soil and atmosphere. The method is explained in the drawing. Above the agricultural field 1, the dimensions of which are determined by the adopted plant cultivation technology, the grid of uninsulated wires l, 2i .... 2p is suspended

The height of the grid suspension and the distance between the wires is determined by calculating the required strength of the electrostatic field in the plant zone or / by calculating the magnitude of the pulsed magnetic fields on the surface and in the root ZON0 of plants created by an electromagnetic generator 3. A switching device is provided in the Generation Worker the specified program to connect to it alternately only two wires, for example, 2

and 2n, Iln is only one of the wires. The common output of generator 3 is grounded. To register a complex of crop determining factors, the appropriate sensors 4 are installed (plant metabolism, photosynthesis intensity, temperature, humidity, solar radiation, wind, etc.) that are connected to the resolver 5, for example, Mini-Computers .

After processing on the computer signals "from. sensors 4 is generated control effect on the electromagnetic generator 3.;,

. / The magnitude of the voltage, its polarity and the time of impact is determined by the decisive

device 5 Depending on the phase of soil moisture (, agronomic experience, and others. At the same time, an adjustable amount of atmospheric electric current is achieved, and the resulting effect can be controlled, for example, by changing the plant 4 plant metabolism.

Thus, sterilization of soil is achieved or an increase in the solubility of fertilizers is ensured; under certain conditions, bio stimulated. soil flora, which allows an increase in the carbon dioxide inflow necessary for photosynthesis of plants. There are also other options for the implementation of the proposed method, for example, irradiation of plants with a directional antenna or mobile installation, or electrification of water sprinkling systems.
