Abstract：Multifunctional aquasorb， degradable soil mulched material， plant drought resistance preparation， soil water relations in the soil plant and air continuum， and soil amendment materials were researched in the project. The characters of aquasorb were optimized. Water adsorbent rate reached to 100， and water release rate was effectively （85%）. The nitrogen and phosphate release capability of fertilizer-supplied aquasorb increased by 10～20 times， and the cost decreased from 20% to 35%. The new developed antitranspiranat could decrease the transpiration by 35%. Soil amendment fertilizer， made from organic and inorganic materials， could increase soil porosity by 5%， and decrease soil evaporation by 10%， and raise the water use efficiency by 20%. Up to now， the divided tasks in the project were carried out according to the plan. Assessment indexes for 2014 were all finished. The quantity of granted Patents reached to 24， and utility model was 2， intellectual property right was 1. There were 75 published papers， included 16 SCI， 18 EI， and 41 CSCD. Depend on the research project， 22 master students and 10 doctor students successfully took their degrees. In the further research， the great innovative achievements would be summarized and proposed. The characters should be further optimized， and promote the plant drought resistance products industrialization.

Key Words：Product for plant drought resistance；Aquasorb；Fertilizer-supplied aquasorb；Antitranspirant；Soil amendment
