Abstract: In order to study the characters of temperature and humidity in colony of rice cultivars with different type, using 3 cultivars as materials (Shendao-11, Liaojing-294, Shennong-9816), the temperature and humidity in colonies of different types of rice were analyzed. The result indicated that among the different rice cultivars colonise of rice varieties, the diurnal variation of the temperature and humidity is consistent with the atmosphere. The pulsatile change of dew point in colonies was bigger than that of temperature and humidity. The variational current of dew point was high at noon. The difference of humidity is much larger than the difference of temperature in rice colonies. The difference of temperature and humidity in colonies of rice cultivars were gradual augmentation from the first ten days of August to the middle ten days of September. The temperature in colony of curved panicle cultivar was higher than that of erect and semi-erect panicle cultivars from August to the middle ten days of September. But the humidity in colony of curved panicle cultivar was lower than that of erect and semi-erect panicle cultivars at the same period. The distinction of temperature and humidity in colonies were unconspicuous between the erect and semi-erect panicle cultivars.
