摘　　要：为解决马铃薯种植过程中常用赤霉素催芽浓度争议较大易造成植株徒长、种薯腐烂等问题,以克新23为材料开展盆栽药效试验,评价硼酸钠、碧护、超敏蛋白对马铃薯发芽至苗期的影响,探索替代赤霉素的可行性。结果表明,硼酸钠会抑制马铃薯出苗及苗期生长,但会增加主茎数及鲜重,适宜浓度为0.7 mg·L^(-1);超敏蛋白对马铃薯出苗及生长等方面的促进作用相对较小,能够增加植株鲜重,并对萌发期至苗期病害具有一定防治潜力,适宜浓度为670 mg·L^(-1);碧护具有相对较好的促进地上部生长、增加主茎数量及壮株效果,适宜浓度为145 mg·L^(-1)。实际生产中可使用145 mg·L^(-1)碧护制剂喷淋薯块至表面湿润后晾干播种,这种改良的催芽方法可提高马铃薯主茎数量,并增加苗期茎粗、植株生长速度、地上部鲜重和地下部鲜重,具有替代赤霉素的潜在价值。Gibberellin is often used to promote germination in the process of potato planting,but the concentration of gibberellin is controversial,and it is easy to cause problems such as plant overgrowth and seed potato rot.To solve this problem,experiments were carried out to evaluate the effects of sodium borate,Bihu and harpin on potato from germination to seedling stage,and to explore the feasibility of replacing gibberellin.The results showed that sodium borate inhibited seedling emergence and seedling growth,but increased the number of main stems and fresh weight.The appropriate concentration was 0.7 mg·L^(-1);Harpin had a relatively small promoting effect on seedling emergence and growth,can increased the fresh weight of plants,and had a certain potential to prevent and control diseases from g ermination to seedling stage.The appropriate concentration was 670 mg·L^(-1);Bihu had a relatively good effect of promoting shoot growth,increased the number of main stems and strengthening plants,and the appropriate concentration was 145 mg·L^(-1).Spraying potato blocks with 145 mg·L^(-1)Bihu solution until the surface was wet and then drying and sowing can increase the number of main stems of potato,and increased the stem diameter,plant growth speed and aboveground and underground fresh weight at seedling stage,it has potential value to replace gibberellin.
