Influența produsului pe bază de Cu și Mn asupra căderii premature a frunzelor la pomii de măr altoiți pe portaltoiul MM106

Abstract

The experimental plot is placed in the orchard “Codru-ST” Ltd. founded in 2010 year. The study subject of the experience was Idared apple variety grafted on MM106 rootstock.The trees were trained as slender spindles for distance 4.0 x 2.0 m. The research was conducted during the period of 2013 year. To study the influence of fertilization with Cu and Mn to increasing the fall of the leaves after fruits harvesting in apple plantation were experimented the following variants: 1. Control – without treatment; 2. Blattab - 5.41 l/ha;3. Blattab - 6.85 l/ha. The Blattab fertilizer was sprayed in different period. The first treatment with Blattab was given after fruits harvesting, the second - after the first in interval of 10 – 14 days. In the present research work, we demonstrated that Blattab fertilizer increased the fall of the leaves in apple plantation and prepares better plants for the repose period and may be included in the technology system, applied 2 sprays at dose 5.41 l/ha. The first treatment was doing after fruits harvesting, the second an interval of 10 – 14 days after the first.
