Abstract:

In the storage of wheat large warehouse, according to a computer system, the measured temperature year grain temperature, storage temperature and the thermometer at the same time testing the temperature outside as the basic reference data warehouse, analysis of temperature, storage temperature, the average grain Matakura temperature, levels the average grain temperature and the average pay a modest four directions of the regional average annual variation of grain temperature. The results show that: Under normal circumstances, temperatures affect the storage temperature, storage temperature affect the grain temperature. Annual variation amplitude: Temperature "warehouse temperature, storage temperature and" grain temperature; storage temperature lags behind air temperature, grain temperature and storage temperature lag. The average grain temperature and the upper most affected by the temperature, the lower minimum; all levels of the average grain temperature and temperature affected by the size of the upper "upper" classes "in the middle and lower classes. Four-week average grain temperature with the seasons changed markedly. East side of the average grain temperature and the smallest fluctuation in the year. The average grain temperature outside to outside factors such as sunlight, temperature and so a great impact, followed by the central region, the smallest fluctuations in the Central region. Point temperature in the direction of the regional temperature distribution are quite different analysis of the data used for the regional average, so the correct food temperature curve can not fully reflect the regional variation. Therefore, the division of the region to be further scientific improvements.
