Description

The invention relates to agriculture, in particular to the seed production of table carrots.

The purpose of the invention is to increase the yield and reduce the prevalence of root crops diseases.

In the first decade of August (after harvesting peas or grain crops), carrots are sown with a norm of 8–9 kg / ha, which provides a density of about 2–10 plants. By the onset of negative temperatures, the plants form 5-6 developed leaves and a root crop 0.54 cm in diameter. In winter, such plants pass through a stage of rovization and are capable of forming flower stalks, i.e. form a crop of seed n. Before going under winter, the crops are mulched with plastic wrap, and then small-sized tunnel shelters with a height of 0.40.6 m in the ridge are installed over rows.

Example. Experiments were conducted on carrot varieties Canned and Artek. The crops were placed in the second crop after the pea. The soil was prepared by a superficial method (disking, sowing, cultivation), and a herbicide was introduced before sowing. Broadband sowing was done using SKON-4,2 seedling rate of the first class of seeds of 8–9 kg / ha; after sowing, if necessary, watering was performed. By the end of the growing season, the plants formed roots weighing 5-30 g. At the onset of stable cold (end of the season), the crops were mulched with a film and tunnel shelters were installed. After overwintering, the safety of plants was 96-98%. In early spring, after the leaves had grown, the plants were transplanted, while in

Each nest was placed 2-3 plants, then watered. Harvest amounted to 15 q / ha. It has been established that a hectare of transplanting plants (density about 2 -10 / Ha) ensures planting of seed plants in an area larger than South.

Seedlings of carrots of August sowing time in open ground should be grown at a density of 1.5-2.0-U6 plants / ha. With such a density, high-quality seedlings are obtained, the land is used more rationally, since 1 hectare of sowing ensures the planting of 13 hectares of seed plants. With the planting method of growing seeds, 1 ha of queen cells provides planting of 2 ha of seed plants. In thinned crops, roots overgrow (diameter greater than 1.5 cm), which adversely affects their overwintering. In more thickened crops, small plants (1-3 mm in diameter) are formed, which do not go through the rovization stage.

Overwhelmed under a film cover (tunnel) and transplanted in the spring to a new place carrot seedlings averaged over 3 years in terms of survival, were inferior to the queen cells, and even exceeded them in better versions (Table 1).

Testicars grown from seedlings are less affected by the disease. Thus, among the testes from the queen cells of the patients there were 33-38% of plants, from seedlings - only 11-13.5%. Seed plants from seedlings in yield were not inferior to testes from queen cells.

The method of growing carrot seeds did not significantly affect the sowing qualities of the seeds, which met the requirements of class 1 (Table 2). The advantages of the method are

first of all in the ability to reject wild forms.
