Abstract

This invention relates to agricultural production. The purpose of the invention is to increase crop yields by preventing the formation of a soil crust in the seed planting zone. The invention makes it possible to obtain guaranteed seedlings of various crops annually in medium and deep solonets without the use of calcium-containing substances (CaSO4-2H2O) and to increase their yield. For this, when sowing in the upper soil layer or in the whole seed area, the saline soil is divided into two parts. Of these, the soil of the humus horizon is moved to the upper layer of the seed area or the ground grooves are completely covered with it. Another part, the soil of the illuvial horizon (salt), is placed in between the beds along one plane of the common surface or rollers. 8 il.

The invention relates to agriculture (5th household).

The aim of the invention is to increase the yield of crops by preventing the formation of a nightcake in the sowing zone.

FIG. 1 shows the profile of the solontsov night at the depth of seeding of fi fi ordinary sowing; in fig. 2 - the same, with soil crust during the germination of seeds; in fig. 3 - the profile of the sunflower night to the depth of seeding in ordinary sowing, where the upper layer is divided into two parts, of which the soil of the humus horizon is located in the Fray layer of the seed sowing zone, and the second part of the upper horizon. layer between rows; in fig. 4to same, during the germination of seeds; in fig. 5 - profile of alkaline soil on the lip of seeding for 1 sowing; in fig. 6 p) the same. with soil crust in the period of 1 |) sprouting of seeds; FIG. 7 solo profile of the soil to the depth of seedling of seeds 11 | P1 furrow seeding, where the soil is divided into two parts, of which the humus horizon is filled with seed grooves, and the illuvial horizon soil is located in the rollers between the grooves; FIG. 8 the same, in the period of 11ro) astani seed n.

Example 1. Conventional seeding (Fig. 1-4). During the nasal period, the upper saline soil layer 1 is divided into two parts. At the same time, the soil of the first horizon is shifted to the nerve layer 2 of the seed distribution zones, and the soil of the illuvial horizon is shifted to the nerve layer 3 between the rows.

After sowing in the area where the podsontsovuk) soil was not separated (Figs. 1 and 2), floppage formed precipitation on the coast; this prevented the seedlings of the seeds 5 from reaching the surface. and in the areas (Figs. 3 and 4), where the upper sodic soil layer was divided and the soil of the humus horizon was located in the area of sowing of seeds, and the soil was il.1K) nialog () orisspga - between the rows.

sprouts of 6 germinating seeds appeared on the day surface.

Example 2. Furrow seeding (Fig. 5-8). During the sowing period, when cutting the furrows, the solonetz soil in the sowing zone of the seeds is divided into two parts, then the soil 7 grooves 7 are filled with humus horizon, and the soil of the illuvial horizon is placed with rollers 8 between the grooves.

After sowing in the area where the prn cuts of the fissures did not separate the sodic soil (Fig. 5 and Fi 6), a continuous crust 9 was formed from precipitation, which prevents sprouts of germinating seeds 10 from reaching the surface, and in areas ( Fig. 7 and Fig. 8), where the alkaline soil in the sowing zone was divided and the illuvial horizon was displaced between the rollers 8, the soil crust 9 in the sowing zone did not form, and the germinating germinating seeds on the surface.

Thus, when applying the proposed method for medium and deep solonetz, no soil crust forms in the seed area, and this creates real conditions for guaranteed annual germination and normal development, followed by an increase in crop yields by 2-3 times. At the same time, the economic efficiency of I ha from the non-use of calcium-containing substances (CaSO4-2HiO) is 80-250p, which is caused by different norms of ameliorant.
