Means of mechanization in promising technologies growing of cereals

Abstract

Studies found that the most promising technology of soil preparation under crops are minimal systems and their varieties technology "No-till" based on the use of seeders for direct seeding. As a result, the proposed technological scheme of seeders direct seeding. The results of field studies to determine the qualitative performance of seeders direct seeding in comparison with conventional technology shown. Analysis of the results of seed depth in soil shows that the greatest number of seeds on the horizons of incorporation at a given depth with acceptable agronomic deviations (±15%) observed in the variant seeding tillage attachment to the grain seeder. The lowest number of seeds in the horizons of 0,5 - 4,0 and 6,0 - 8,0 cm was observed in the variant of sowing sweeps paws-openers. Comparing the distribution of seeds in the horizons of 0,5 - 4,0 and 6,0 - 8,0 cm at sowing in the variant grain drill according to the traditional technology of tillage and sowing with the seeder attachment the removal of seeds in upper and lower soil layers in the second case, less than 26% and 30%, respectively. The introduction of the proposed machinery and tools will allow you to download the tractors HTZ class 3 t. that will allow retooling of the existing fleet of agricultural machines due to the greater versatility of the planters and their lower cost.
