Abstract

Procédé plus intensif de culture de plantes cultivées et la régulation de leur alimentation grâce à la combinaison d'un traitement chimique et d'une technique appropriée de culture. Les plantes cultivées sont traitées avec une composition contenant de l'acide 2-chloro-éthane-phosphonique, des micro-éléments et des additifs. Pendant une certaine phase de leur développement, la phase végétative, un engrais à base d'azote est appliqué aux plantes en même temps que le traitement chimique ou avant celui-ci, et l'on procède à un traitement fongicide. Si l'on souhaite augmenter le nombre de souches, l'engrais à base d'azote appliqué est divisé en des portions plus nombreuses et d'autres moyens techniques sont utilisés pour augmenter l'efficacité des compositions. L'invention permet une augmentation excellente de la valeur des plantes et du rendement des récoltes.
