Phenological Phases and Meteorological Elements Interaction

Popis výsledku v původním jazyce

The paper deals with evaluation of phenological data series of sugar beet, sum of daily average active air temperature (5, 10 and 15 oC) and length of the vegetation season. The average value of phenological phases onset and the beginning of agronomic practices of two long-term periods (1931-1960, 1960-1990) were compared. A prolongation of the interval between sowing and emergence was proved. The length of growing season was different at analyzed stations. Sowing of sugar beet is on average performed in earlier time. We are not able to determine significant trend. This may be due to high-performance agronomy machines that are used in agriculture. A thirty-year trend analysis (1961-1990) of sugar beet phenological phases shows significant changes in phenological phases sowing (20 days) and emergence (14 days). Significant trend was found in case of phenological phases sowing (r = 0.510) and emergence (r = 0.445). Active sum of daily average temperature above 5, 10 and 15 oC and length of the vegetation season which is given by values of the daily average values of air temperature exceeding given threshold (5, 10, 15 oC) are addressed in this work. The average values of four long-term periods (1931-1960, 1961-1990, 2021-2050, and 2071-2100) were compared to one another. The comparison of sum of active air temperature and vegetation season length proved their gradual increase and prolongation from 1931-1961 to 2071-2100.
