Abstract

The invention relates to the treatment of soil, including fertilization techniques. The purpose of the invention is to increase the yield of cotton by improving the water-physical properties of the soil and supplying plants with nutrients. By locating fertilizers (nitrogen-potash fertilizers in the upper russia and phosphorus fertilizers in the lower russians), nutritional improvement of cotton plants is achieved due to the improvement and continuity of nutrient supply. The water-physical properties of the soil in the pre-sowing treatment system are improved by loosening two depths in a single pass of the unit and subsequent band milling to a depth greater than the depth of seeding. 2 Il.

Description

The invention relates to the treatment of soil, including fertilization techniques.

The purpose of the invention is to increase the yield of cotton by improving the water-physical properties of the soil and supplying plants with nutrients.

FIG. 1 is a schematic diagram of the execution of the process by the unit, side view; in Fig. 2, loosened strips with fertilizers introduced in the dynamics of growth and development of cotton, a cross section.

The method is carried out as follows.

A set of working bodies is hung on the two-bar frame of the 1 gun, and the articulated legs 3 are installed on the front bar 2 of the frame, carrying out the first lane tillage to a depth of 15–20 cm and a width of 20–30 cm with the introduction of easily absorbable mineral fertilizers

through the pipelines 4 from the bunker 5, deep loosening paws 7 are installed on the second beam 6, followed by the paws 3, for cutting deep gaps 50–60 cm deep and 10–15 cm wide.

From this bunker 8, fertilizer, which is difficult to assimilate by plants, is fed into this slot through 20 pipe lines with a height of 20-30 cm from the bottom of the slot, thus giving a T-shape to the fertilizer column. Further, using milling tools 10, the separation of the pads 6 located behind the paws and hinged on the second bar, the strip loosening the surface of the soil layer to a depth of 6-10 cm and a width of 15-30 cm. opening furrow for the guide wheel of the tractor of the sowing unit.

The fertilizer apparatus is driven in the usual way, for example from

basic and driving wheels 12 guns. Driving a tractor with a mounted implement is made by marker.

The proposed cotton cultivation method ensures the implementation of a one-pass aggregate of high-quality soil preparation steertf: Ha 30% of the area of the cultivated field, while using known technologies, the treatment is carried out repeatedly in different directions, causing soil compaction. According to the proposed technology, the total annual rate of phosphate and potash fertilizers, as well as half of the nitrogen fertilizers, is applied during the presowing treatment, 2 or 3 times less than the known technologies. Movable (soluble) fertilizers are introduced into the upper rus and accelerate the growth of cotton in the initial period, and stationary (phosphate and potash, combined) fertilizers introduced to the entire depth of loosening, as the core root grows and become fully utilized. only cotton, not weeds in each phase of development.

FORUMAWLAH AND ISLANDS

A method of preparing the soil for sowing cotton, including loosening and fertilizing in two rivers, characterized in that, in order to increase yields by improving the water-physical properties of the soil and supplying plants with nutrients, loosening is carried out before sowing in the future simultaneous application of fertilizers with a single stream of nitrogen and potassium forms to a depth of 15–20 cm in the form of a horizontal strip and another of phosphorus fertilizers in the form of a vertical strip to the depth of loosening, after which

surface milling of future rows with a depth greater than the seeding depth is carried out.

Claims (1)

Claim A method of preparing soil for sowing cotton, including loosening and fertilizing in two tiers, characterized in that, in order to increase productivity by improving the water-physical properties of the soil and supplying plants with nutrients, loosening is carried out before sowing strips in the area of future rows with simultaneous application fertilizers with one tier of nitrogen and potassium forms to a depth of 15-20 cm in the form of a horizontal strip and another tier of phosphorus fertilizers in the form of a vertical strip to the depth of loosening, after which surface milling of the zone of future rows with a depth greater than the depth of seed placement.
