Resumen
Las cubiertas vegetales se utilizan para reducir el gran deterioro que presentan los
suelos de olivar debido a la erosión. En este trabajo se ensaya con 17 especies
autóctonas de las cubiertas herbáceas de nuestros olivares, analizando el éxito y la
curva de germinación acumulada bajo diferentes tratamientos de fertilización del suelo.
Las siembras se realizaron en condiciones de jardín experimental diferenciando dos
tratamientos: con abono (NKP) y sin abono. El objetivo es determinar el éxito de
germinación de las diferentes especies para así obtener cuáles son las que mejor se
adaptan a las condiciones de suelo manejadas. Nuestros resultados mostraron que la
mayoría de las especies ensayadas presentaron una mayor germinación en suelo no
fertilizado y las que mayor tasa de germinación para ambos suelos fueron Cleonia
lusitanica, Vicia sativa, Vicia peregrina, Medicago sp., Calendula arvensis y Trachynia sp.
Plant covers are used to reduce the high deterioration of olive groves due to erosion. In this work, 17 native species of the herbaceous cover of our olive groves are tested analyzing the sucess and the germination curve accumulated under different soil fertilization treatments. The planting was carried out in experimental garden conditions using trays with soil from an olive grove, distinguish two treatments: with fertilizer (NKP) and without fertilizer. The objetive is to determine the germination sucess of the different species in order to obtain those that are best adapted to the soil conditions handled. Our results show that most of the species tested showed increased germination in unfertilized soil. In addition, the species tested that had a higher germination rate for both soils were Cleonia lusitanica, Vicia sativa, Vicia peregrina, Medicago sp., Calendula arvensis and Trachynia sp.
