番茄结果期冠层叶-气温差的影响因子研究
Research on the Impact Factors of the Canopy Leaf-air Temperature Difference in the Tomato＇s Fruiting Period
摘要
Abstract
This paper has analyzed the relationship between Canopy leaf-air temperature difference （△T） and soil volumetric water content （SW） during the tomato＇s fruiting period. The results show that： in the sunlight, the canopy temperature （Tc） change consistently with the temperature （Ta）, and Tc and Ta reached the maximum value during 13：00-15：00 for the leaf evapotranspiration being the strongest at this time which very easily lead to water shortage of tomatoes. It is also found that there have good linear negative correlation between AT and SW at 14 ： 00, threshold of the AT is -- 1.5 ℃ in the tomato＇s fruiting period, and the plant will be in the state of water shortage when the AT is greater than or equal to -1.5℃.关键词
