In order to research the spray of LPG/diesel mixed fuel, it is the first time that this work studied the atomization characteristics of LPG/diesel, including spray angle, droplet size distribution, mean diameter, typical diameter, diffusion degree and impenetrate distance by using a high spatial resolution digital camera. At the same time, comparison of these characteristics of diesel and two kinds of LPG/diesel mixed fuel was taken.

The results showed that:Under NaCl stress,the reductions in the shoot and root dry weight, leaf area,stem diameter of grafted plant were lower than those of ungrafted plants.The Na~+ content,Na~+/K~+ ratio,Na~+/Ca~(2+) ratio in the leaf and scion stem of grafted plants were lower whereas those of in the rootstock stem ad root were higher than in ungrafted plants. The K~+ contents,soluble sugar contents,shoot water contents,SOD,POD,CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance were higher,whereas the MDA contents in the leaf of grafted plants were lower than that in ungrafted plants.The reductions in leaf area and stem diameter of grafted \'Jinchun No.2\' plants were more severe than those of grafted \'Zaoduojia\' ones.
