| Abstract: | We carried out the comparative test to study the effects of different dosages of controlled-released fertilizer specially used for potato on yield increasing of Qingshu No.9 in winter potato planting area of southwest Sichuan . The results showed that, the best fertilization scheme was applying 60 kg/667 m2 controlled-released fertilizer specially used for potato as base fertilizer. The treatment had the heaviest average single plant weight and highest marketable tuber rate, and the fresh tuber yield was 2 114.0 kg/667 m2, which was increased by 1 063.5 kg/667 m2 compared to the control treatment (no fertilizer application), with the yield increasing rate of 101.2%. |
