Device for sterilizing soil electrical shock

The invention relates to methods of electromagnetic influence on soil

The invention relates to agriculture, mainly to agriculture and is used for sterilization of soil from harmful microfloras root-knot nematodes and complexes of phytopathogenic fungi (fusari, rizoctonia and t,d), for example, in greenhouses

Apparatus has electric heating chamber, blade-type screw located within said chamber and provided with drive comprising electric engine and reducer. Electric heating chamber is made in the form of two coaxially arranged pipes, of which inner pipe is connected with phase drive and outer pipe and electric engine casing of blade-type screw are connected with earthed zero wire.

Apparatus has working chamber, electromagnetic vibration source, transportation device, charging and discharge device, moistening device, moisture content and temperature sensors, apparatus controlling unit, electrode gap adjustment device and water feeding regulator. Apparatus is further provided with microprocessor for automatic controlling of disinfection procedure. Moistening device is made in the form of agitator having two offset blades and moisture content and temperature sensors positioned in the vicinity of bases of said blades. Telescopic piston is mounted in upper part of agitator and is provided with through-flow water feeding cannel formed centrally of telescopic piston. Through-flow channel is made bifurcated at site near agitator blades so that lateral channels are formed, said channels being terminated with high-pressure nozzles. Working chamber has two vertical parallel plates, namely, high potential plate and low-potential plate.

Device contains direct current source with pole selector switch and unipolar electrodes, one passive and at least two active ones, at that passive electrode is installed in reservoir made of ion-conducting material, and active electrodes are fixed at brackets that have been installed on this reservoir. Method of device usage consists in immersion of active electrodes into processed medium, and passive one is placed into reservoir filled with water, at that reservoir with passive electrode is installed in the centre of treatment zone, and active electrodes - in radial directions in respect to this reservoir.

Method includes tillage by a pulse electromagnetic wave with right-sided elliptical polarisation with energy flow density of 1-1.500 J/m². Prior to tillage, organic remains and fertilisers are added to the soil, primarily manure. The device comprises a modulator, connected to a high-frequency oscillator, a unit of operation mode setting and an antenna track with a radiator. The appropriate output of the operation mode setting unit is connected to the inlet of the modulator. The radiator comprises radiating elements. The device additionally comprises a switch with one high-frequency input and high-frequency outputs and a unit of switch control. The output of the mode setting unit is connected to the input of the switch control unit. The output of the switch control unit is connected to the control input of the switch, the appropriate outputs of which are connected to radiating elements.

Invention relates to agriculture. According to the disclosed method, a decomposer which is susceptible to electromagnetic waves is first dispersed on the soil surface, followed by exposure of the treated area to microwave radiation. The decomposer used is a substance in liquid form or solutions which release atomic oxygen under the effect of microwave radiation, specifically hydrogen peroxide or sodium peroxydisulphate solution.

Invention relates to the field of agricultural machinery industry, in particular, to devices for destruction of weeds, providing the impact of high-voltage current. The device comprises a movable unit, a source of electric power and working elements. The source of electric power is made in the form of a resonant system of electric power supply. The source of electric power comprises a primary source of electric power supply, an inverter, a resonant transformer. The source of electric power is located stationary in close vicinity to the cultivated land. The device comprises a single-conductor power line. Output of the source of electric power is connected to the input of the single-conductor power line. The output of the single-conductor power line is connected to the input of the electrode section with the working elements.

Invention relates to agriculture. For cultivation of globe-thistle and phacelia at a field contiguous to apiary, before planting the seeds of the named plants are granulated and moistened for 3-5 mines in weakly alkaline or neutral solution consisting of clay, black soil, waters and wood ash in a proportion 1:1:1:0.01, then they are dried up on the net with the mesh size no more than 2 mm, and phosphate and potassium fertilizing are brought into soil. Seeds are planted during May 20-25 into the prepared seed beds to the depth 2.8-3.2 cm with the interval between plants 30 cm, inter-row interval - 25 cm with account for blooming during June 20 - July 10. During blooming the preventive harvesting of blooming cultures is performed on the area amounting up to 40% of cultivated terrain.
