Abstract

The conducted research is devoted to biodiversity, namely the cultivation of planting material of European larch through the use of intensive farming methods, as an integral technological method of cultivation and, at the same time, an ecological and meliorating factor of impact on the surrounding natural environment, which are quite widely used not only in Ukraine, but also in the border It has been established that a feature of growing high-quality planting material is the use of mineral fertilizers. The results of experimental studies showed that the pre-sowing application of ammophos had a significant effect on the height of the seedlings, the diameter of the root neck and the length of the roots. Fertilization of seedlings with urea-ammonia mixture solution had a minor effect on these indicators. The cumulative effect of organized factors (influence on the linear indicators of seedling feeding with urea-ammonia mixture solution at pre-sowing application of 4 and 8 g/p.m of ammophos) had a significant effect on the height, diameter and length of the roots. It has also been proven that the above-ground application of amphos has a positive effect on the mass indicators of European larch seedlings, in particular, it increases the mass of needles, trunks and aerial part, as well as the mass of the root system. According to the results of the experiment, it was determined that the introduction of ammophos has a positive effect on the yield of standard European larch seedlings. When applying ammophos at a dose of 4 g/p.m, the yield of standard seedlings was 78%, and when applying 8 g/p.m — 88%, which is higher than in the control group without fertilizer application (the yield of standard seedlings was 45–50%). Therefore, the introduction of amophos in the specified doses can be an effective measure to ensure a high yield of standard larch seedlings.
