Development of process flow charts for growing ball-rooted planting stock: issues and solutions

Abstract

In order to create process flow charts for more efficient operation of enterprises for the production of pine and spruce ball-rooted planting stock for reforestation, research and comparative analysis of technologies of three nurseries in the Arkhangelsk region were conducted. Significant differences in capacity, equipment sets, greenhouse characteristics, number of rotations, etc. in greenhouse complexes do not allow the development of a single standardized document. The results of the analysis allowed us to divide technological methods into two blocks: the main ones and additional (or auxiliary) ones. The first block of operations in the process flow charts of different nurseries will differ in time, duration and ways of their realization. The second one consists of those operations that are carried out only under certain conditions of forest nursery functioning, with the appropriate equipment of enterprises and their financial capabilities. The results of the conducted comprehensive research will serve as the basis for the development of regional documents, which will offer the most rational methods of carrying out certain types of work, as well as build a chain of technological operations for growing high-quality planting stock in a particular greenhouse complex.
