Model of creation of productive agrocenosis of Echinacea

摘要

The results of many years of field research on the effect of stocking density of different types of Echinacea spp . on its productivity are discussed. It was found that when the Echinacea purpurea crops were thickened, the collected raw material had a high percentage (more than 50%) of stems, which negatively affected its quality. An increase in the density of Echinacea pallida crops has less effect on the formation of generative shoots. Long-term research has revealed patterns that determine the productivity of Echinacea spp . at different planting densities. This made it possible to calculate and recommend for production the density of plants at which the optimal yield of the agrocenosis will be achieved: for Echinacea purpurea – 100-110 thousand/ha, and for Echinacea pallida – 120-140 thousand/ha.
