Abstract

This article highlights information on the development of new techniques for preparing the planting area of nurseries for growing seedlings of ornamental trees and rare flowers. In forestry, the use of modern energy-saving agricultural machinery to create optimal conditions for plant growth allows for high volumes of product with minimal labor and material costs. Agricultural machines used today do not fully meet the agrotechnical requirements of technological operations. Therefore, it became necessary to improve the design of the combined tillage used, which in one pass carry out various work on preparing the soil for sowing, and for this, first of all, it is necessary to improve their working bodies that will produce a good air-water soil exchange. In the proposed technology, the furrow former of the complex tillage system reduces the accumulation of soil clods under the working body, forming optimal furrows for planting ornamental trees and seedlings of rare flowers. And since a complex operation is carried out in one run, it reduces the other cost. A plow with two moldboard bodies, of a combined tillage system, must comply with the requirements for use, and at the same time, the height of the moldboard plow opening furrows must be at least 20.5 cm, opening angle of the share wings is 60-65º, the angle of entry into the soil is 35-40º, the angle of the side cut of the wings of the working body is 37-40º, the width of the share wings is not less than 41 cm, the body length of plow must be not less than 78 cm.
