Опыт и перспективы освоения хурмы Виргинской в фиточайной культуре

Abstract

The purpose of the research is to develop optimal technological parameters for the formation and methods of seasonal exploitation of phyto tea plantations of Virgin persimmon for the purpose of phyto meliorative development of low-productive sandy lands of the region. At the end of the last century, under the conditions of increasing climate change in the Eastern Caucasus, at the experimental site for the introduction of woody flora, the Achikulak NILOS VNIALMI, work began on the adaptation in the temperate zone of the region of a number of economically valuable subtropical crops, including the Virginian persimmon (Diospiros virginiana. L) for the purpose of phyto meliorative development of low-yielding sandy lands in the most thermally secure part of the territory, on the sands of the Tersko-Kuma interfluve. The potential of its naturalization is manifested not only by high tolerance to the environment (heat resistance, drought resistance, frost resistance), but also by significant nutritional value, along with fruits and leaves of a woody plant, with a hgih content of bioactive substances (vitamins, organic acids, minerals, etc.), which determines the possibility and prospect of developing a subtropical perennial in a phyto tea culture cultivation of caffeine-free raw materials of medicinal leaf drink. The work was completed in 2012‑2020 to develop effective methods for the formation, operation of persimmon tizan plantations and utilization of its leaf mass into valuable organic products for food and medicinal purposes
