Electro-technological operations with planting material in horticulture and forest protection plantations

Abstract

The presented analysis of the conducted research allows us to speak about the possibility of a wide and technologically effective application of electro-technological operations for the preparation of healthy seedlings in the interests of horticulture, agroforestry and ornamental gardening. The use of electrophysical effects allows one to achieve high planned efficiency in the growth and development of seedlings of woody plants and splicing grafts of horticultural crops. This minimises negative anthropogenic impact on the environment and reduce the total cost of preparation of planting material. The tasks outlined in the first part can be achieved by using electrostimulation of shrub and tree seeds in the electric field of alternating high voltage, with subsequent growing of seedlings from them in a climatic chamber specially made for these purposes for afterglow. There, the optimal regime for their development and growth is created. The issues of fruit-tree grafting survival were studied separately. To solve this problem, the modes of active influence on the grafting place by electric current by means of specially made applied electrodes were studied. The voltage supply to the electrodes ensured the direct current flow through the grafting site with the required density not damaging plant tissues from 0.25 to 1.50 μA/mm2. The duration of such treatment aimed at achieving a positive effect of grafting is 7…10 days, as for example, the grafting of seed woody crops. The researched method can be recommended as an effective technological operation for grafting grapevine or a grafting place of cultural rose cuttings with local “native rosehip that are most resistant to external influences..
