STRIP SEEDING OF GRASS IN MEADOWS

Abstract

For the successful development of animal husbandry in Ukraine, it is necessary to increase the area of pastures for which it is necessary to lend some of the arable land and re-plant some of the existing pastures, creating cultural pastures with a productivity of 60-80 c. fodder units per hectare. For rejuvenation of existing grasslands, the technology of direct sowing with minimal tillage is increasingly used. These technologies include operations to suppress existing grasses and sow the seeds of valuable fodder grasses into grooves specially prepared in the turf. Domestic and foreign experience shows that sowing herbs in pre-treated strips is more effective than traditional methods. The traditional technology of re-insulation of such bows is associated with considerable energy and labor costs and is also erosion-hazardous in areas with a slope angle exceeding 3%. Therefore, for such areas it is necessary to use re-salting technology without completely destroying the turf and to use special seeders of different designs, which perform in one pass the strip tillage, sowing of grass seeds and sealing. Therefore, this method of redevelopment is highly productive and therefore promising in Ukraine. The idea of sowing grass seeds in a cultivated strip of soil in the turf is the basis of the technology of direct accelerated grassland re-grassing. The cultivated strip of soil must meet the agrotechnical requirements for the quality of cultivation in growing grasses. The implementation of the proposed technology of direct strip sowing of grasses in the existing herbage is possible only in the presence of perfect working bodies. Foreign and domestic seeders intended for direct sowing of herbs in the turf do not fully meet the agrotechnical requirements for the quality of processing of the turf strip, so the technology of direct sowing with a developed, active working body in the form of a cutter is proposed.
