Invasive species are an important problem for agricolture. For this cause, a study has been done about rice’s weeds, in particular about Echinochloa crus-galli e Oryza sativa var. sylvatica. These two species are the main weeds in rice’s colture and can harm the mechanised harvest and limit the production. Two weeds have been sown in some trays with inside steril soil and for each ecotype four reproduction have been obained. After having collected the data, in costant way, about their germination, these data have been processed in relation to the temperature measured with data logers. In this waywe know the emergency dinamics and we can limit and control their growth through correct period of false sowing.
Le infestanti sono una problematica importante per l’agricoltura. Per questa ragione è stato svolto uno studio sulle malerbe del riso ( Oryza sativa), in particolare delle malerbe Echinochloa crus-galli e Oryza sativa var. sylvatica. Queste due specie sono le principali infestati nella coltivazione del riso e possono ostacolare la raccolta meccanizzata e limitano la produzione. Le due malerbe sono state seminate su delle vaschette con terreno sterile e per ogni ecotipo sono state ottenute quattro repliche. Dopo aver raccolto i dati, in modo costante, riguardo alla loro germinazione, questi sono stati elaborati in relazione alle temperature misurate con i data logers. In questo modo conoscendo le dinamiche di emergenza si può controllare la loro crescita attraverso il periodo di falsa semina.

Abstract
Invasive species are an important problem for agricolture. For this cause, a study has been done about rice’s weeds, in particular about Echinochloa crus-galli e Oryza sativa var. sylvatica. These two species are the main weeds in rice’s colture and can harm the mechanised harvest and limit the production. Two weeds have been sown in some trays with inside steril soil and for each ecotype four reproduction have been obained. After having collected the data, in costant way, about their germination, these data have been processed in relation to the temperature measured with data logers. In this waywe know the emergency dinamics and we can limit and control their growth through correct period of false sowing.File | Dimensione | Formato | |
