Abstract

The invention relates to the field of agriculture, in particular to ameliorative tillage. The chain of the invention is an increase in the quality of non-lorative treatment of sodic soils. A device for carrying out the method comprises a roller 5 installed in front of the rotary cultivator 6. The rotor of the rotary cultivator 6 has knives made in the form of plates. The free ends of the knives are bent at an angle of 10-25 °; to the plane of rotation of the rotor. The knife is set at a cutting angle of 35-45 °. and made with a concave curved section along the radius of a circle, equal to 0.7-0.8 length of the cutting edge of the knife. Rink 5 precipitates the seam to the bottom of the furrow, partially compresses it on the ripper 6 and crushes the layers of the alkaline layer, moving them vertically and horizontally with knives. The roller 8 aligns the floor with a bar and compacts the soil. Before mixing the formations, a solonet formation is compacted and compacted. The mixing of the alkaline and salivary layers is performed by moving the layers across the cut solonetz formation. Before rolling, level the floor. 2 sec. and 1 z. p. f-ly, 4 ill.

The invention relates to agriculture, in particular to ameliorative tillage,

The purpose of the invention is to improve the quality of ameliorative treatment of sodic soils.

Fig. 1 schematically shows a device for processing sodic soils, side view; Fig 2 - the rotor ripper; on fig - rotor knife, front view; figure 4 is the same, side view about

The proposed method is carried out as follows.

First, the solontsy layer is cut, loosened with a rise, followed by a draft of the raised layer and its reinforcement. Then, the solonetz and subsalt layers are mixed, which is performed by moving the layers across the cut solonetz formation. After mixing the layers, the floor surface is leveled with rolling

A device consisting of a frame is used to implement the method of treating sodic soils; 1 with support wheels 2 and a hinged device Zo On frame 1, a flat-cutting machine A, an additional roller 5, a rotary ripper 6 with a drive mechanism 7 and a bar roller 8, the Rotor 9 of the rotary ripper 6 has knives 10, made with angle 10-bend 25 ° and set at a cutting angle of 35 "o.45. The blade 11 of the knife 10 is made with a cut along the arc of a circle R 0.5 ,,, 0.651, where 1 is the length of the knife.

The device works as follows.

When moving across the field, the cutting paw 4 cuts the sunflower and sodic layers, opens them to the bottom of the furrow and partially crumbles.

An additional roller 5 compresses the soil converging from the paw 4, and the formation of sediment to the bottom of the furrow occurs. Ripper 6 crushes the layer of mixing the sunflower layer with sodic vertically. During the operation of the rotor 9, the knives 10 move the layers of the soil layer along the axis

rotor. The bar roller levels the floor and compacts the soil.

The proposed method of treating sodic soils improves the degree of crumbling of sodic soils and improves the mixing of sodic and subsalt salts, which creates better conditions for the development of cultivated plants,

Claims (2)
