EXPERIENCE OF APPLYING OF ENVIRONMENTALLY SAFE GROWTH REGULATORS WHILE GROWING SEEDLINGS OF WHITE FIR <i>(ABIES ALBA </i>MILL.) IN CONTAINERS
Growing quality planting material is one of the priority tasks of modern nursery farming. Improvement of technology occurs, among other things, through the search and use of new fertilizers, growth regulators, pesticides, etc. Particular attention is paid to environmentally friendly drugs, which include Rostmoment, VG and peat oxidate, 4% w. In this study, we studied the effect of these drugs on the biometric parameters and the safety of white fir seedlings (Abies alba Mill.) When grown in containers. The experiments were carried out for two years. The preparations were applied in the form of solutions of 1, 2 and 3% concentration, as well as in dry form in the amount of 10, 20 and 30 ml per 1 liter of substrate during pickling of seedlings. It was found that it is advisable to use a 2% solution of Rostmoment with annual 3-fold treatment of plants. The introduction of the drug into the substrate in a dry form is not recommended. The use of peat oxidate as a growth regulator in concentrations of 1, 2, and 3% for fir seedlings is ineffective.
