Rational use of seedling greenhouse complexes during off-season period

A new approach to the use of seedling complexes of greenhouse farms in the new field of renewal of the Russian forestry is presented. Due to the current situation in the forestry of the Russian Federation, the problem of updating vast areas of forests that have undergone intensive logging and fires has arisen. Studying the Decree of the Government of the Russian Federation of June 8, 2022 No1043 «On Amendments to the Regulation on the Specifics of the Use, protection, protection, reproduction of forests located on agricultural lands' and the Decree of the Government of the Russian Federation of June 15, 2022. No1064 «On Amendments to Appendix No10 to the Decree of the Government of the Russian Federation No353 dated March 12, 2022», as well as a number of additional documents on this issue, the authors of the article had a proposal to address this issue. Obtaining planting material of a wide range of forest tree species is possible with the use of domestic equipment and intensive hydroponic technologies, which are widely used in the world and in the Russian Federation in greenhouse vegetable growing. Seedling complexes are part of greenhouse enterprises and produce planting material all year round, without restrictions. The problem of restoration of forest lands in the Russian Federation is extremely relevant. For this purpose, there is a material and technical base of the greenhouse vegetable growing sector, numbering more than 200 farms capable of mastering the production of seedlings of young plants of various tree species. The need for planting material only for coniferous trees at the moment is 165 million pieces. In this regard, in order to cover the stated needs, the capacity of forest nurseries available in the Russian Federation must be increased by 3 times. The national project «Ecology» has been approved, designed to increase the area of reforestation to 100% by 2024. The urgency of creating the latest nurseries for growing tree seedlings in protected ground conditions, where all modes of growing young tree seedlings are automatically provided, has been confirmed. Many years of experience in creating and operating seedling complexes in the structure of greenhouse complexes of the Russian Federation will reliably provide a solution to this issue, since there is already a real practice of growing them on the basis of Nizhny Novgorod JSC «Dzerzhinskoe».
