Technological platform for the cultivation of barley in the Krasnoyarsk forest-steppe

Abstract

Abstract The results of the research aimed at developing a technological platform for the cultivation of barley are presented. The technological platform is a pyramid of seven biogenic energy flows. At the base of the pyramid there are streams with sustainable natural potential. They include the conditions of the territory (climate, weather and soil with its natural level of fertility). They mainly determine the choice of variable flows - crop, variety and cultivation technology. The most changing factor with a wide range of changes is the cultivation technology. The technology is directly dependent on the soil, the climate, and the weather and is closely related to anthropogenic impact. The main variable fluxes of biogenic energy include the availability of available moisture, nutrients and weediness of crops. The tillage is the regulated, most costly energy flow. In the experiment, soil cultivation was carried out according to the traditional technology based on fall tillage (control) and minimal. Herbicide treatment allowed to reduce the contamination of the crop for harvesting by 60%. The harvest was formed in harsh weather conditions, grain. Wheat grains, on average, were obtained at 29.2 c / ha, barley - 22.0 - 26.5 c / ha.
