Technology for Soil Treatment in Rows of Seedlings and Saplings of Forest and Horticultural Crops

Resumo

Analysis of the mechanization level in soil treatment for plantings of seedlings and saplings of forest and horticultural crops that is necessary for weeding, keeping soil in a loose state, introducing nutrients into the root layer of the soil, etc. has revealed that interrow treatment has a 100% result. However, the plant rows that include protective zones remain untreated in this case, which requires a considerable amount of manual labor, which is 40–50 people/h per ha to perform the row treatment operation. The best option for the care of planted seedlings for saplings of forest and horticultural crops is the reequipment of the cultivators with a KRN mechanism that allows them to process the soil, simultaneously performing soil-treatment operations both in rows and row spaces. All known methods of tillage in rows require the use of special mechanisms that loosen the soil in a row and cut weeds. Such executive devices must create a necessary protective zone around plants. The developed structure of the mechanism is installed on the KRN row cultivator over the processed row, which simultaneously processes row spaces and rows. The results of the theoretical studies of the developed mechanism are presented.
