Simulation-dynamic model of prediction of phytometric parameters of vegetative shoot of horsetail (Equisetum arvense L.) in wild coenopopulation

Studies of wild-growing coenopopulations of horsetail were carried out in the period 1995 ...2022 in the Kostroma region in order to develop a simulation-dynamic model of the seasonal forecast of phytometric parameters of the vegetative shoot of horsetail for planning the timing and volume of collection of medicinal raw materials. Verification of the model showed the accuracy of the forecast: shoot height - 81.10...85.35%; aboveground active phytomass - 83.6...96.6%, depending on the year of the study, which makes it possible to predict the timing and volume of collection at least 60...80 days before the start of industrial harvesting of medicinal raw horsetail.
