The use of Albit in the technology of growing grafted seedlings of technical grape variety

Abstract

In 2014-2016 were laid 2 experiments: 1. Processing during the stratification period; 2. Processing during the growing season in the nursery garden, the purpose of which was to determine the effectiveness of including foliar fertilizing (Albit) in the conditions of the Lower Don region in the technology for the production of grafted planting material for industrial grapes. The treatment of vaccinations during the stratification period has a positive effect on their yield, which increases to 65.6-92.2%, which is 5.6-32.2% more than the control, with a positive correlation to an increase in concentration. The final yield in this experimental variants varied from 32.2 to 48.9%, significantly exceeding the control by 14.4-31.1%. Treatment of grafts during the growing season in a nursery garden with a solution of Albit in a similar concentration contributed to the aerial parts, roots, increasing the survival rate to 50.3-64.6% (increase to control 2.1-16.4%) and the final yield up to 33.3-57.2% (increase to control 10.0-33.9%), with a positive correlation to an increase in concentration. Foliar treatment during the growing season in a nursery garden with a solution of the Albit preparation provided the formation of a more powerful annual growth with increased quality indicators compared to the control.
