The resistance to pulling the working part where the manure juice is poured locally

Abstract

The object of the research consists of the architecture of the root system of intensive garden soil and trees, the process of interaction of the aggregate and its working part with the soil and roots, which pour the fertilizer juice locally. The only way to grow ecologically clean products from the garden is to feed the fruit trees locally with manure juice. In intensive gardens, it is advisable to pour the manure juice into the zone of branching tree roots 0.8–0.1 m long, 20–30 sm deep, and an average width of 15 sm. In the process of cutting the soil and roots of the working part of the fertilizer juice pouring unit, the force of gravity is formed. A dynamometer was used to determine the force required to cut the roots. To do this, it was dag a hole of 80 sm long, 30 sm deep and 15 sm wide along the row, without damaging the roots, leaving a distance of 20 sm directly from the trunk of the tree in the garden. The soil-cleaned roots were pulled into a dynamometer loop, pulled until they broke, and the breaking force was determined. For gardens, pouring sap on average 1 m long, 25-30 sm deep and 12-15 sm wide, leaving a protection zone of 20-25 sm from the trunk, increases the efficiency of fertilizer use. In the local method, the gravitational resistance of the working part, which pours the juice to depth, is on average 3.5 kN.
