| Abstract: In order to explore the best fertilization method for potato growth and yield in dry land of Lanzhou, a field experiment was carried out by a randomized block design. The results showed that under local conditions, the average yield of treatment A2 was 57.88% higher than that of A0 (CK), and all agronomic traits performed better. The best fertilizer combination scheme for potato production was the reduced fertilization with N 40 kg, P2O5 40 kg, K2O 20 kg, potato formula fertilizer 30 kg and soil conditioner 30 kg per 667 m2, which should be popularized in the dry land of Lanzhou. |
