中文摘要	在内蒙古清水河县进行大田试验,研究3种保水材料(聚丙烯酸钾、聚丙烯酰胺和腐殖酸)及不同施用年限对旱作谷子苗期生长特性及土壤水分的影响,筛选出适合该地区抗旱保苗的保水材料。结果表明,各保水材料处理均能提高出苗率,2011年表现为Al > Bl > C1 > CK,较CK提高了7.57~12.88个百分点,2012年表现为A2 > B2 > C2 >A1 >B1 >C1 >CK,较CK提高了0.76~12.88个百分点,2013年表现为A3 > B3 > C3 > A2 > B2 > C2 >A1 >B1 >C1 =CK,较CK提高了0.00~20.45个百分点;保水材料对谷子株高和鲜干重具有显著影响,且连续施入3年的效果优于施入2年和只施入1年的,但在株高方面,保水材料的年际效果差异不明显;保水材料可以提高0~100cm土层土壤含水量和贮水量,0~60cm各土层各处理差异明显。因此,3种保水材料均具有明显的蓄水保墒效果,提高谷子出苗率,促进谷子生长,以连续施用3年聚丙烯酸钾和聚丙烯酰胺效果最好。
英文摘要	Through the field trails in Qingshuihe county of Inner Mongolia,this paper studied the effect of three water-retaining materials which are PAA(A),PAM(B) and HA(C) and their different application time on seedling growth characteristics of millet and soil moisture in dry-farmland,in order to select suitable water-retaining materials for crop emergence and seedling growth in the arid region. The results showed that these water-retaining materials can improve the seed emergence rate of millet. In 2011,the seed emergence rate of millet was Al > B1 > C1 > CK and it increased by 7.57% to 12.88% compared with CK,in 2012,the result was A2 > B2 > C2 > Al > B1 > C1 > CK,and it increased by 0.76% to 12.88% compared with CK,in 2013,the result was A3 > B3 > C3 > A2 > B2 > C2 > Al > B1 > C1 = CK, and it increased by 0.00% to 20.45% compared with CK; These water-retaining materials have significant influence on plant height,fresh and dry weight of the millet,and the effect of three-years continuous application is better than both two years and only one year, but the interannual effect of every water-retaining material on the plant height is not obvious; These water-retaining materials can improve the moisture content and the water storage of the soil layers from 0 - 100cm depth, and the differences of each treatment in the 0 - 60cm depth soil layer are distinct. So three water-retaining materials have obvious effect of water retaining and conserving, improve the emergence rate of millet and promote the growth of Millet,and the effect of three-year continuous application of PAA and PAM is the best.
