| 摘 要： | 研究了保水剂拌种和基施对小麦生长的影响。结果表明：两种方法均能促进小麦返青及中后期生长，株高、整齐度、叶面积等性状显著优于对照，穗粒数、千粒重比对照增加10％-15％，产量增加17％以上；保水剂基施具有明显的持效性，第二季小麦的土壤含水量比对照提高了0．8～4．6个百分点，两季小麦共增产27．8％。 |
| 关 键 词： | 保水剂 小麦 拌种 基施 持效性 |

| Abstract: | The effects of seed dressing and base fertilizer with water-retaining agent on wheat growth were studied. The results show that the two methods could promote turning green and the growth in middle-late stage of the wheat, and their plant heights, uniformities and leaf areas preceded significantly than those of CK. Also, the number of spike kernels and thousand-grain weight increased by 10%-15% compared with CK, and the output increased above 17%. Furthermore, the basal application of water-retention agent had hold-efficiency characteristics obviously, the soil moisture content in the second season increased by 0.8%-4.6% compared with CK, and the output increased by 27.8%. |
| Keywords: | water-retention agent wheat seed dressing basal application hold-efficiency characteristic |
