“…Based on the goals and objectives of the study, as well as the analysis of studies conducted to study the shortcomings of the technical workflow of the devices mentioned above, to eliminate the existing shortcomings and solve the problem of mechanization of sowing seeds of saxaul and cherkez, which do not scatter over the entire area of the field in rows, with the release of seeds in the prescribed amount, the technology and design of the seed drill have been created, which allows sowing seeds within the regulatory interval and at a shallow depth, while not clogging seeds from inside the hopper and without negatively affecting their biological fertility. The newly proposed technology and the seeder's design and technological process are protected by a patent of the Republic of Uzbekistan [18,19,20. The novelty of the design of the seeder and the technological workflow lies in the fact that a trapezoidal hopper consisting of two parts is recommended for the row in which the seeds are sown.…”

The article provides information on large degraded areas in almost all areas, of which 17.5 million hectares of dry natural pastures are allocated for cattle breeding out of 32 million hectares of desert and semi-desert areas in Uzbekistan. It is also noted that 40% of desert and semi-desert pastures have degraded pastures to varying degrees, the average productivity has decreased by 20-30%, and 8.0 million degraded pastures should be improved first. To improve the condition of degraded desert and semi-desert pastures, the authors noted that it is possible to increase their productivity by 10-15 times due to the establishment of cultural pastures by replanting nutritious wild plants and comparing their productivity. To improve the productivity and ecological restoration of degraded livestock pastures in our Republic's desert and semi-desert areas, he considered the mechanization of planting saxovul and cherkez plants from nutritious shrubs and developing a planting unit for this purpose. For this purpose, the devices used in planting the seeds of plants with the same physical and mechanical properties as the desert plants from the seeds of nutritious plants growing naturally in the wild in our Republic and foreign countries and their shortcomings have been determined.

“…Given the need to improve the condition of desert pastures and combat their degradation, it is necessary to mechanize their sowing, in particular, to develop and introduce seeders. Based on the need for mechanization of sowing seeds of desert fodder plants, we have developed seeders for sowing seeds of desert fodder plants [21,22,23]. Also, a universal sowing unit has been developed for sowing seeds of desert fodder plants (Fig.…”

This article presents the extensive agricultural characteristics of fodder plants growing wild in nature, which are the most promising shrub and semi-shrub fodder plants for the creation and development of cultivated pastures in degraded karakul (sheep) pastures. Also, the fact that out of 17.5 million hectares of land allotted for karakul breeding in the desert and semi-desert zones of the Republic, which up to 40 percent are degraded to one degree or another, their average productivity has decreased by 21 percent. The authors of the article analyzed degraded pastures in desert and semi-desert zones of Uzbekistan and foreign countries and ways to improve their condition. A method is recommended for restoring degraded pastures by mechanizing the sowing of seeds of shrubs and semi-shrubs. Studies on the mechanization of sowing small-seeded and non-flowing seeds show that, firstly, the mechanized sowing of desert fodder plants is largely carried out on the basis of agrotechnical methods in conditions that do not correspond to the specific conditions of deserts, and secondly, shrub and semi-shrub plants and their seeds have physical and mechanical properties that are very different from other crops and seeds. A universal sowing unit is recommended, which consists of a four-sowing machine, which, in one pass of the technological process of work, sows seeds of shrubs and semi-shrub desert fodder plants with relatively close seed sizes. At the same time, the hoppers of the sowing unit are filled with 1, 2, 3 or 4 types of seeds of different plants and the seeds are sown. During the operation of the unit, the first hopper of the sowing machine is filled with shrub seeds (for example, saxaul) and the hoppers of the remaining 2, 3 and 4 sowing machines are filled with one or different types of seeds of semi-shrubby plants (Izen, keiruk, teresken), etc. The universal sowing machine sows seeds in one direction 3.6 m wide, and when returning, it also sows seeds 3.6 m wide, forming a pasture strip with a total width of 7.2 m. In the first row, it sows the seeds of a shrub plant (for example, saxaul seeds) and, in the remaining 2, 3, 4 rows - different types of seeds of semi-shrubs, for example, seeds of izen or seeds of other semi-shrubs, while on both edge rows of the pasture strip, he sows seeds of shrubs between them, sows seeds of semi-shrubs and creates a pasture-protective strip, consisting of shrubs and semi-shrubs. Simultaneous sowing of shrubs along the two edges of the strip provides for the protection of these undersized semi-shrubs from heat, strong wind and dust, as a result of which they develop better. The following parameters of the universal seeding unit were determined: the speed of movement of the unit is 1.38 -2.22 m/s; working width of the universal sowing unit 3.6 m; quantity of the sowing device 4 pieces; distance between sowing units 0.9 m; the number of seed mixture mixers in the lower part of the hopper is 6 pieces; lengths of cone-shaped fingers softeners of the seed mixture 7.0 cm; normalizing drum radius 5.0 cm; number of revolutions of the normalizing drum 26-30 r/min; length of the normalizing drum 7.0 cm; quantity of triangular chute 8 pieces.

“…As a result of a critical scientific analysis of the shortcomings of the devices mentioned above, a sampling drum with measuring grooves was created for the universal seeding device of an innovative seed drill, which provides ordinary row sowing of seeds of the desert forage plants, including saxaul and cherkez, while ensuring the established norms and consumption of seeds and between nests (figure 1) [13][14][15][16][17].…”

A review of technologies for sowing non-loose seeds of forage plants shows that seeders and devices that fully meet the requirements of agricultural technology have not yet been created. The available tools do not provide a stable sowing of seeds and their uniform placement in the field, so the distances between the nests are not the same in a row. The authors recommend designing the sampling drum for an innovative universal seeding machine with measuring grooves that ensure the same distance between the seed nests in a row, corresponding to the agrotechnical requirements for seeds. The main requirement when creating a seeder was the need to determine the number of grooves that determine the distance between the nests at different speeds of the unit. In addition, it is also required to ensure that the measuring grooves are filled with the required amount of seeds, which depends on the speed of rotation of the sampling drum. Based on preliminary laboratory experiments and theoretical studies, the optimal parameters of the sampling drum were determined: the diameter of the sampling drum is 100 mm; the speed of rotation of the sampling drum is 8-15 rpm; the number of measuring grooves – 10-12 pieces. These parameters at a speed of MTA -1.44 m/s provide the distance between the seed nests in a row and are 0.5-0.7 m.
