【Abstract】 The effects of different types of fertilizers on the potato yield and tuber characters were studied in this paper.The results showed that compared with ordinary compound fertilizer,the long-term potato-specific fertilizers,which were produced by the Germany’s BASF,and the Soil and Fertilizer Institute,Guangdong Academy of Agricultural Sciences,could lead to 17.3% and 9.1% total tuber yield increases,11% and 6% marketable tuber yield increase,and 671.7 Yuan and 372.0 Yuan increase on a basis of 667m2 land,respectively.Therefore,the long-term potato-specific fertilizers have significant role to play in both yield and income increase.It can be recommended to use in winter potato production.更多还原
