Abstract
El objetivo de este trabajo fue evaluar el manejo y operación del riego en la aplicación de agua y el efecto en la producción del frambueso de variedad Dolomia. El estudio se llevó a cabo en dos huertos regados por microriego que están ubicados en la Región del Biobío (Fundo “Santa Sara”) y Ñuble (Fundo “Monterrico”), respectivamente. En Santa Sara se aplicó un tiempo de riego (Tr) que varió entre 9 a 120 min diarios, mientras que en Monterrico el Tr varió entre 5 y 6 horas con una frecuencia de 2 a 3 veces por semana. Se analizó la eficiencia de aplicación del sistema de riego y el efecto de 2 y 3 laterales de riego, en la determinación de los factores de demanda F1 y F2 para los meses de diciembre y enero, usando la evapotranspiración de referencia desde estaciones meteorológicas cercanas a los sitios de estudio y los obtenidos mediante imágenes satelitales. Los resultados mostraron que la variación del caudal aplicado entre el primero y el ultimo gotero de los laterales fue de 99% y 12% en los sitios del Fundo Santa Sara y Monterrico, respectivamente. Los valores de los factores para dos laterales fueron F1= 0,0101 y F2= 0,11 y para tres laterales F1= 0,0096 y F2= 0,132 en el sitio Santa Sara, mientras que para el sitio de Monterrico fueron F1= 0,009 y F2= 0,11. Estos Parámetros son representativos del frambueso durante el periodo de análisis, ya que, consideran las condiciones climáticas de la zona y la etapa fenológica del cultivo.
The objective of this work was to evaluate irrigation management and operation in water application and the effect on production of the Dolomia raspberry variety. The study was carried out in two orchards irrigated by micro-irrigation. A and B are located in the Biobío Region (Fundo "Santa Sara") and Ñuble (Fundo "Monterrico"), respectively. In Santa Sara, irrigation time (Tr) varied between 9 and 120 min with a daily irrigation, while in Monterrico the Tr varied between 5 and 6 hours with a frequency of 2 to 3 times per week. The application efficiency of the irrigation system and the effect of 2 and 3 irrigation laterals were analyzed in determining the F1 and F2 demand factors for the months of December and January, using reference evapotranspiration from meteorological stations near the study sites and those obtained from satellite images. The results showed that the variation of the applied flow rate between the first and the last dripper at the leterals was 99% and 12% at sites Santa Sara and Monterrico, respectively. The factor values for two laterals were F1= 0.0101 and F2= 0.11 and for three laterals F1= 0.0096 and F2= 0.132 at site Santa Sara, while for site Monterrico were F1= 0.009 and F2= 0.11. These parameters are representative of the raspberry during the period of analysis, since they take into account the climatic conditions of the area and the phenological stage of the crop.
