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.
