Abstract

Abstract: Potato variety Qingshu 9 was used to study the effects of different film colors and fertilizer types on potato growth, yield and quality in the southern mountainous area of Ningxia. Two factor random block design with nine treatments combining 3 film colors （no film, white film and black film） and 3 fertilizers （no fertilizer,formula fertilizer and controlled-release fertilizer） was used. Results showed that treatment of formula fertilizer with white film cover had fast growth, short growth period and the highest yield of 32 515 kg/hm². Treatment of controlled-release fertilizer with black film cover showed the highest potato starch content of 19.81 g/100 g. Treatment of formula fertilizer with black film cover got the highest potato vitamin C content of 23.41 mg/100 g. These results could provide certain reference for the potato industry in the southern mountainous area of Ningxia.

Key words: potato（Solanum tuberosum L.）, black film, white film, yield
