Abstract

The purpose of the invention is to increase the yield due to the rational use of the energy reserves of seeds. The method of sowing crops includes the formation of a bed for seeds, their sowing and embedding. New is the fact that the bed for the seeds is formed in the form of a ribbon with a dense, without disrupting the capillaries, the bottom shifting the loosened layer of soil into the interstitial space. Seeds are sown scattered with the simultaneous formation of a soil ridge of 4-5 cm in height by the reverse transfer of the soil displaced by the coulters, which is then trailed and rolled.

Description

The invention relates to agriculture, in particular to methods of sowing crops.

The known method of sowing seeds includes the pre-sowing treatment of the surface layer of the soil, the formation of a furrow for the seeds by shifting the soil layer into the interstitial space, compaction of the bed, sowing the seeds and their incorporation by reverse transfer of the soil displaced into the interstitial space.

The disadvantage of this method is the irrational use of energy reserves of seeds with their deep seeding and a decrease in yield.

The purpose of the invention is to increase the yield due to the rational use of the energy reserves of seeds.

The goal is achieved by the fact that in the method of sowing crops, including pre-sowing treatment of the surface layer of the soil, the formation of furrows

for seeds by moving the soil layer into the interstitial space, compacting the bed, sowing the seeds and replanting them by reverse transferring the soil displaced to the interstitial space, the surface soil layer is treated by harrowing, and when forming a seed furrow, the soil layer is cut in the interbranch space without rotation of the reservoir, and the seeding is carried out by transferring along with a loosened layer and an additional cut layer with the formation of a soil layer 4-5 cm in height, which is then train and roll,

Example. Pre-sowing tillage is carried out, for this the surface layer of the soil is treated by harrowing

The seed bed is formed with wedge-shaped openers with a lid and a flat bottom in the form of a tape 12 cm wide with dense

bottom by moving the loosened soil layer in a horizontal plane into the interstitial space (18 cm distance between the interstitials). During the formation of a groove for seeds, soil is cut in the inter-belt area without turning the formation. Through these wires, the seeds from the hopper enter the vomer and are scattered on an even, dense bed. Seeding is carried out by disc gateways by transferring, along with a loosened layer and an additional cut layer, with the formation of a soil layer 4-5 cm in height, which is then shuffled and rolled up with the NCSCH-6.

The height of the soil layer above the seeds after shaving and rolling is 2.5–3 cm. In the seed embedding zone, the average daily temperature of the soil is 0.8 ° C higher than in the control variant. The seedlings appeared 2 days earlier, the fullness of the seedlings increased by 13.2% and the survival rate of the plants was 9.2%. The weight of all weeds in the total mass was less than the control by 13.6%. Due to the finer placement of seeds, the distance from the seed to the main tillering node (basal area) has decreased

by 2.0 cm. The yield increase amounted to 5.1 q / ha (see table).

The application of the proposed method of sowing allowed to increase the yield.
