Влияние некорневой подкормки селеном растений листовой редьки на качество готовой продукции

Abstract

The influence of foliar selenium fertilization of vegetative plants of leaf radish on the quality of finished products is considered. The object of the study is a variety of leaf radish VR–Tv-28 of South Korean selection. Scheme of experience: NPK (background) – control option; NPK + BUT Se 0.0005%; NPK + BUT Se 0.001%; NPK + BUT Se 0.002%; (selenium concentrations). The repetition is threefold. Macro fertilizer used as a background and introduced into the soil during sowing in an amount of 30 g/m2 is nitroammophoska. The plants were treated with a solution of sodium selenite by spraying in the phase of mass molting of the root. In the background versions, the plants were treated with distilled water. It was found that selenium fertilization in the form of non-root treatment of vegetative plants of leaf radish of South Korean selection (variety VR-Tv-28) with sodium selenite solution did not affect the content of dry matter and dry soluble substances, but caused a decrease in the content of ascorbic acid in plants and a decrease in the content of nitrates in the leaves of leaf radish of this variety. It was determined that the use of this type of selenium fertilization of leaf radish plants led to an increase in the concentration of selenium in the leaves by 1.2-1.8 times compared with the control and did not affect its accumulation in the roots.
