本研究主要确定吸收剂量率对两类吸水树脂性能(吸水性能、接枝率)的影响，为工业上大量辐照吸水树脂的辐照工艺提供理论依据。使用60 Coγ辐射引发农用吸水树脂接枝交联。实验结果表明：总剂量为4~10 kGy的情况下，剂量率较低时(0.8~1.2 kGy/h)合成类的吸水树脂聚合不完全，不能形成最终的达标产品；淀粉类吸水树脂在设定的剂量率范围内，可完成反应。剂量率对合成类和淀粉类吸水树脂的吸水倍数、凝胶强度都有一定影响。在此剂量率范围的试验样品接枝率都在95%以上；由于实验使用的交联剂较少，因此剂量率对交联度的影响不大。合成类树脂的保墒效果较好，试验15 d后土壤含水量最高为17%，延长灌溉周期15~20 d；两类吸水树脂的催芽效果显著，均在93%以上。

This research mainly is the study of absorbed dose rate on the performance of the two types of inj ectivity resin (water absorption performance,grafting rate).The experimen-tal results show that the increase of the dose rate can be improved water absorbing ratio, grafting ratio and swelling ratio.Crosslinking agent used in this study is less,and low dose rate of experimental group could not complete the experiment.The synthetic inj ectivity resin cannot complete reaction when the dose rate is 1 kGy/h.Field experiments show that water absorption resin for soil has obvious effect of water and promote the germination effect,soil moisture content as high as 17% after 15 d,15 to 20 d extending irrigation cycle.Seed germination rate is over 9 3%.
