| Abstract: | Field experiments indicate that using the multi functional drought resistant reagents on winter wheat enhanced the stomatic resistance of leaf and decreased plant transpiration, thus decreased water consumption, retarded the senescence of leaf and prolonged the wheat filling. Furthermore, the reagents reduced the water loss rate of leaf, strengthened the capability of reserving moisture and increased the filling rate, yield and water use efficiency. It is proved that the reagents can produce great economic benefits and is worthy of popularization. |
