Determination of Irrigation Regime and Optimization of Hydromodule Schedule for Forest Nursery

Abstract

The article discusses the detailed methodology for designing irrigation systems, determining the irrigation regime, and optimizing the hydromodule schedule for a forest nursery. The research object is a 23-hectare nursery divided into four main sections. Based on soil-climatic parameters and active layer depth, irrigation norms and hydromodules were calculated for each section.

Analysis of the uncompleted hydromodule schedule showed a peak discharge of 0.508 l/s/ha. Through optimal rescheduling of irrigation periods, the maximum hydromodule was reduced to 0.300 l/s/ha (a 41% reduction), and the maximum water intake (Q_gross) of the farm decreased from 156 l/s to 93 l/s.
