Abstract

In the north, seeds are mainly grown in greenhouses with polyethylene coating. The growth of seedlings mostly depends on the microclimate, substrate, and the availability of mineral nutrition and moisture. Intensified silvicultural production and greater volumes of planted crops call forth increased production of planting stock. In addition to mineral fertilizers, vermicompost is one of the promising fertilizers in planting stock cultivation. It contains a balanced complex of necessary nutrients and trace elements, enzymes, soil microorganisms, humic compounds and vitamins. The study aimed to develop a science-based technology of growing pine seedlings (Pinus sylvestris L.) in greenhouses using dry vermicompost. In the experiments, the seedlings were grown bare-root in nursery conditions in the substrate with addition of various doses of dry vermicompost without mineral fertilizers. The results have shown that seedlings grown with addition of vermicompost are just as high as those grown on the traditional mineral nutrition. In greenhouses with polyethylene coating, dry vermicompost proved to be efficient and have a positive effect on the germination of seeds and growth of seedlings. For pine cultivation we recommend applying 1.5 kg/m2 (15 t/ha in total) of dry vermicompost broadcast over the bed surface.
