In order to study the effects of the new plant grow mixed compound on lodging properties and photosynthesis of spring maize in cold area. In the experiment, three kinds of the chemical control agent were selected, two chemical control agents had been used in field production, the name were Yuhuangjing and Duntianbao. The third mixtures was laboratory configuration which the main ingredient was DCPTA and CCC. The results showed that, after FPJ and YHJ agent handling, reduced plant height and ear height, reduced the length of basal internodes and increased basal diameter of maize. The treatment of DTB could increase plant height and ear height and internode length. For example, after 10 days of tasseling, compared with the control the section length of 1, 3, 5 of the treatment of mixtures reduced by 12.62%, 9.49%, 6.51% and internode diameter increased by 13.70%, 12.37%, 12.69%. Compared mixtures, the length and diameter of internode were little difference with Yuhuangjing and Duntianbao. The mixtures processing could increase dry matter accumulation of the stems of maize, part of the difference was significant. Compared with the control, the leaf area index of the treatment of the mixtures was difference, which was not significant. After treating of the mixtures, the values of chlorophyll fluorescence of Fo and qN declined, the values of Fv/Fm and qP increased in the leaf of in maize, this result showed that mixtures spraying processing not only had a role to reduce plant height, increase lodging resistance traits also promoted photosynthesis of maize, eventually lay the foundation for high yield of maize.
