Abstract

The effect of Super Absorbent Resin (SAR) on soil characteristics and production of wheat was conducted to study in a potted cultivated experiment, with Jimai 22 as experimental material and adopted single factor block design under the dry farming condition. The results show that: the application of SAR in dry-land wheat, increases degree of soil Relative water content among the whole growth period, especially in tiller stage, heading stage, grain-filling stage, but in Jointing stage and mature stage (require less water), it effected less obviously. Within a certain range, SAR can increase leaf water use efficiency in dry-land wheat and the more SAR, the bigger soil water content and leaf water use efficiency. But litter effect on Wheat Soil hydrogen ion concentration (pH). The SAR has positive impact on wheat yield component factors and yield.
