摘　　要：研究了安徽省农科院原子能应用研究所用强化辐射交联技术制备的超高吸水性新型功能高分子材料 (新型抗旱保水剂 )在改良土壤和作物抗旱节水中的效果。结果表明 ,新材料能降低土壤容重 ,显著提高土壤毛管持水量、总空隙度 ,显著提高盐碱土的透水速率。新材料有很好的抗旱保水效果 ,在土壤干旱时显著提高小麦、玉米出苗率 ,轻度水分胁迫下 ,1g/kg(土 )处理即有显著抗旱作用 ,对甘蓝包菜生长有明显促进作用 。The super-absorbents,prepared from Co r radiation polymerization with novel cross linker by Institute of Atomic Application in Agriculture of AAAS,was studied.The influence of it on soil improvement and drought resistant and water saving for crop growth was investigated.The results indicated that novel super-absorbents induced volume weight of soil,prominently increased capillary moisture capacity of soil,total interstices and water penetrating power of salt-alkali soil.Novel super-absorbents had better drought resistant and water-saving effects,which can enhance seedling-forming percentage of wheat and corm when soil was in the condition of drought.When the content of the polymer in soil was 0.1%,it can promote the growth of cabbage.In short,the novel super-absorbents were better materials with the resistance to drought and water-saving.
