FOUNDATION OF TIPE AND PARAMETRES OF WORKING BODIES FOR STRIP-TILLING SOIL FOR SOWING SECOND CROPS

The proposed resource-saving technology consists in ridge sowing seeds of second crops in the rows of cotton, after harvesting the planting filler crops of winter wheat for grain, which was sowing along the slopes of irrigation furrows. After harvesting the cotton stems and planting filler crops of winter wheat, which falls on next year, the soil of the cotton ridge is loosened by strip-tilling and the second crops are sown in the cotton ridge by one pass of the aggregate. Aggregate replaces 3 agricultural machines and performs functions: undercutting and complete destruction of vegetative weeds; cutting the ridge soil in a vertical plane along the line of separation of the furrow slice from the array along the future seed row and partial milling of soil and trash; mulching the surface of the dried up soil layer of the ridge; minimal cultivation of ridge soil, combined with mulching the surface with trash of cotton; intensive crumbling and loosening of the lower soil of the ridge without turning it to the surface; preparation of a leveled hard bed; dotted sowing of seeds second crop in the ridge of cotton.

A scheme for arranging the milling and chisel working bodies on the beam of a row cultivator, as well as their rational parameters, has been developed. Soil solidity at the tops of the ridge, on the slopes of the ridge and in the furrow determined. It is in limit 5,4…12.5 % which completely satisfy to agrotechnical demands.
