Seed processing aid

The invention provides a seed processing aid. The seed processing aid is prepared from an aid, wherein by counting the total weight of the seed processing aid at 100 percent, the aid is prepared from the following components by weight percent: 1.0 to 10.0 percent of pentaerythritol, 5.0 to 30.0 percent of ethanol, 5.0 to 30.0 percent of urea, 5.0 to 20.0 percent of glycerinum and 0 to 84 percent of water. By virtue of the synergistic effect of the components of the aid, the seed processing aid has low temperature resisting characteristic, so that coatings formed by processing the seeds with a seed coating agent comprising the seed processing aid are uniform and firm and low in stripping rate, and the hazard problem caused by the poor low temperature resistance of the seed coating agent can be solved. 本发明提供了种子处理助剂。本发明种子处理助剂包括助剂，以所述种子处理助剂总质量为100％计，所述助剂包括如下质量百分比的组分：季戊四醇1.0％-10.0％、乙醇5.0％-30.0％、尿素5.0％-30.0％、甘油5.0％-20.0％、水0-84％。本发明种子处理助剂通过所含的助剂组分所含的成分之间协同作用，赋予本发明种子处理助剂耐低温特性，使得含有本发明种子处理助剂的种衣剂在低温下对种子处理所形成的种包衣均匀，牢固，脱落
