Measurement of the temperature change throughout an ensiling process process was done, using thermocouples made by copper and constantan placed in a tower and an earth-pit silo containing a green maize silage.
The relationships between the changes of the numbers of some microörganisms and that of the material temperature in an ensiling process were disccussed.
In the ensiling process, there were three maximums of temperature chagnes. So, it was assumed, that the first peak must be led by the autorespiration of the plant cell, the second was resulted from the growth and the metabolism of some anaerophilic microörganisms, and the third was caused by the action of some aerophilic one. The maximum value of the temperature in each layer was found at 4, 10 and 20 days after packing, corresponding to the upper, middle and bottom layer, respectively. This means that the grade of aerobicity determines the rise of temperature in each layer throughout the ensiling process.
