Abstract
The paper presents data on the study of the effectiveness of new biological drugs-the biofungicides Trichozan and Vitariz and biological insecticide against the background of the action and aftereffect of the sideral precursors of long-legged flax. The research was conducted in the Scientific Research Center of the Ivanovo State Agricultural Academy in 2018-2020. The positive effect of the action and aftereffect of the sideral precursors on the productivity of plants and the yield of flax was established. The greatest increases in the yield of straw and seeds were obtained in 2019-2020 when flax was placed after the sideral precursors and the complex use of the biological products Trichozan, Vitariz, and Bioinsecticide. The quality of flax straw improved by 0.5-0,25 sortonomer with the interaction of the complex of biological products and the action of siderates and by 0.25 sortonomer-with the use of biological products for the treatment of seeds and plants against the background of the aftereffect of siderates. The level of profitability for the years increased by 41.9-11.7%, respectively.
Highlights
The basis of modern technologies for growing crops is the development and implementation of organic farming, the use of preparations of natural origin (Melnikova, 2019)
The study of new predecessors of fiber flax, their aftereffects is a very urgent topic of research aimed at achieving the productivity potential of varieties
The biopreparations Trihozan and Vitariz, Bioinsecticide, green manure precursors of fiber flax used in the experiments have not been studied before
Summary
The basis of modern technologies for growing crops is the development and implementation of organic farming, the use of preparations of natural origin (Melnikova, 2019). The study of new predecessors of fiber flax, their aftereffects is a very urgent topic of research aimed at achieving the productivity potential of varieties. Biologized technologies are based on the use of biological products to stimulate plant growth and protect against pathogens. A review of literature data shows that the biological products used in the experiments contributed to an increase in the yield of straw and seeds by 16-18%, the level of productivity was 7.2 c / ha of seeds and 11.7 t / ha of long fiber, there are reserves for increasing the yield of cultivated based on the use of more effective preparations and technology for growing flax according to new predecessors. The biopreparations Trihozan and Vitariz, Bioinsecticide, green manure precursors of fiber flax used in the experiments have not been studied before
