摘      要：正 Under field conditions, the sunflower （Helianthus annuus L.） grown in different salt level was studied to photosynthetic rate （Pn） and its influence factors during squaring stage in saline soil, i.e. photosynthetic active radiation（PAR）, leaf temperature（TL）, transpiration（Tr）, intercellular CO2 concentration（Ci）, stomata limiting value（Ls） and stoma conductance （Cs） et
