摘 要：
Experiments with various plant densities and basal fertilizers were carried out in two locations of various latitudes by using the variety E-malingshu 7 with the aim to extend the new potato variety extensively.The plant densities were set at 3 500 hills,4 400 hills and 5 400 hills,and basal fertilizers were 2 500 kg cow dung,25 kg compound fertilizer,and 10 kg compound fertilizer + 25 kg calcium superphosphate based on 667 m2 of the land.The best performance(tuber yield 2 324.5 kg) was achieved when the variety E-malingshu 7 was planted at 5 400 hill and the basal fertilizer was applied at 25 kg of the compound fertilizer regardless of the locations.
