摘要: 研究了黄腐酸对连作马铃薯幼苗生长发育、块茎营养和抗性生理的影响。结果表明,连作马铃薯幼苗生长发育受到显著抑制,而黄腐酸处理对连作马铃薯的生长发育表现出显著的促进作用;黄腐酸处理相对提高了马铃薯块茎的淀粉含量、Vc含量和可溶性蛋白含量;黄腐酸处理显著减小了连作引起的叶片叶绿素、脯氨酸和可溶性糖含量下降的幅度,相对提高了SOD和CAT活性,并降低了MDA含量和活性氧水平。黄腐酸处理减轻了连作所造成的生理障碍,从而提高了马铃薯幼苗对连作障碍的整体抗性,促进了连作马铃薯的生长发育,改善了马铃薯块茎营养。

Abstract: The influences of fulvic acid on the growth and development, resistance physiology and tuber nutrition in the continuous cropping of potatoes were studied. The seedlings endured stress from the soil, and the growth and development were significantly inhibited but, fulvic acid irrigation mitigated the harmful influences caused by continuous cropping, and stimulated the growth and development of continuous cropping potato seedlings. The fulvic acid treatment also significantly alleviated the decline in chlorophyll, proline and soluble sugar contents, promoted the SOD and CAT activities, and even reduced the MDA content and reactive oxygen level. The fulvic acid treatment alleviated the obstacles to continuous cropping and thus improved the overall resistance of potato plants. The fulvic acid treatment also significantly improved the starch, vitamin C and soluble protein contents in potato tubers. It can be concluded that the treatment of fulvic acid not only improved the growth and development of potato seedlings, but also resistance to deleterious effects of continuous cropping, thereby overcoming some of the obstacles to continuous cropping in potato.
