通过对超微粉体种衣剂包衣的２个高产小麦品种生育后期旗叶生理特性的研究表明，该种衣剂对旗叶光合速率、叶绿素含量及产量均有不同程度的积极影响，可以显著提高后期旗叶叶绿素含量及光合速率，从而延缓叶片衰老，延长叶片功能期，增加产量。同时讨论了种衣剂对不同抗性的小麦品种的影响程度，认为种衣剂在抗逆性强的品种上能更好地发挥其应有的功效。
The study on the physiological characteristics of flag leaf in late growth stage of two high-yielding wheat cultivars coated with the superfine powder coating agent showed that the coating agent had positive effects on the flag leaf photosynthetic rate, chlorophyll content and yield in varying degrees, Significantly increase late leaf chlorophyll content and photosynthetic rate, thereby retarding leaf senescence, prolonging the functional period of leaves and increasing the yield. At the same time, the effect of seed coating on wheat varieties with different resistances was discussed, and the seed coating was considered to be able to exert its due effect on varieties with strong resistance.
