Energy balance of ampelocoenosis at different structures of plantation and architecture of plants

Abstract

The purpose. To study energy balance ampelocoenosis and to tap their efficiency. Methods. Field, laboratory and energy-balance. Probes were carried out in 2013 – 2015 on technical cultivars of grape Rubin Tairovskiy, Suholimanskiy belyi and Odesskiy chornyi. Results. On the basis of credit and debit part of energy balance effectiveness ratio of absorbed and general physiologically active radiation of ampelocoenosis with different structure of plantation and architecture of plants is determined. Conclusions. The method of energy balance enables to study experimentally magnitude of entering solar radiation, its absorbtion by leaves and sowings in separate spectral ranges, real photosynthesis and other processes. In the long term this method can be used in probes of production process of plants of grape and development of modern agrotechniques.
