Recommendations. - M. Rosinformagrotech, 2011. 176 s. The conditions of harvesting and post-harvest processing of grain in Siberia are considered, the main factors influencing the high-performance and high-quality performance of harvesting works . are revealed. Scientifically based methods for predicting the timing and rates of ripening of grain crops and patterns are presented , on the basis of which an algorithm has been developed for constructing the expected course of grain maturation taking into account weather conditions , Model for determining the duration and pace of cleaning operations, Post-harvest processing of grain , Preparation of machines for work , Preparation of fields , selection of operating modes of the main working bodies of grain harvesters , grain cleaning machines and dryers. Practical recommendations on the organization and operational management of harvesting operations, the use of new technologies and technical means for harvesting and post-harvest processing of grain are given . The recommendations are intended for scientific, engineering and technical workers, agricultural specialists, university teachers, graduate students and students . Features of cleaning and post-harvest processing in extreme conditions. Ensuring adaptability of technologies and technical means for harvesting and processing of grain crops . Forecasting the timing of maturation and the pace of harvesting of grain crops . Selection of technologies for harvesting grain .
