摘要
系统地研究了日光温室内茄子冠气温差的变化规律与环境因子之间的关系,运用回归方法建立了主要气象因子与冠气温差之间的数量关系。深入分析了不同土壤水分条件下日光温室内茄子冠气温差与土壤含水量的关系,并建立了二者之间的相关方程,得出了诊断茄子水分状况的指标。
The relationship between canopy-air disparity and environmental factors was discussed compre-hensively in solar-heated greenhouse.Meanwhile,the quantitative relationship between canopy-air disparity and meteorological factors was established,Besides,the correlation analysis between canopy-air disparity and soil water content was studied in detail,which indicated canopy-air disparity has a good relationship with soil water content,Furthermore,the study came up with the water diagnosis index of eggplant in solar-heated greenhouse.The test results showed that the index can reflect soil water status well.
