据在国际水稻研究所、印度卡普萨那拉遮光室内、人工控制气候室内、栽培池和田间进行试验,当气温低于30℃时,水稻花内温度比周围气温高0—1℃;当气温高于30℃时,花内温度比周围气温低;当周围的气溫达到40℃时,这两种温度与温差呈线性上升,其差值可以达到2℃。花内外温度还受空气湿度的影响,随着周围空气中的相对湿度下降,温差就扩大,水蒸汽压也就增强。当空气相对湿度在36％时,花内温度为32.4～32.7℃,花周围温度为34.3～34.6℃,温差为1.9℃,水蒸汽压为36毫巴;相对湿度57％时,花内温度为32.7—33.4℃,花周围温度为33.6～34.2℃,花内外温差为0.6～0.8℃,水蒸汽压为24毫巴;当相对湿度为79％时,花内温度为33.4
Experiments were conducted at the International Rice Research Institute, Kapusanlar shelter india, artificially controlled climatic chambers, cultivation ponds and fields. When the temperature was below 30 ° C, the temperature inside the flower was 0-1 ° C higher than the ambient temperature. When the temperature is higher than 30 ℃, the temperature inside the flower is lower than the ambient temperature. When the ambient temperature reaches 40 ℃, the two temperature and the temperature increase linearly, and the difference can reach 2 ℃. The temperature inside and outside the flower is also affected by the humidity of the air. As the relative humidity in the surrounding air drops, the temperature difference expands and the water vapor pressure increases. When the air relative humidity is 36%, the internal temperature is 32.4 ~ 32.7 ℃, the ambient temperature is 34.3 ~ 34.6 ℃, the temperature difference is 1.9 ℃ and the water vapor pressure is 36 mbar. When the relative humidity is 57%, the internal temperature is 32.7-33.4 ℃, the temperature around the flower is 33.6 ~ 34.2 ℃, the temperature difference between inside and outside the flower is 0.6 ~ 0.8 ℃, the water vapor pressure is 24 mbar; when the relative humidity is 79%, the flower temperature is 33.4
