美国、加拿大等发达国家的马铃薯营养管理本着减少环境污染以获得高产的原则,遵循最佳管理实施BMP)的策略,避免因肥料过量使用造成不必要的损失和浪费。马铃薯需肥量是由其生长量、生长阶段、天气状况和品种所决定的。而肥料的施用量主要依据土壤的供肥能力、肥料的潜在损失和作物的生产潜力(Dean,2004)。不同的生长发育阶段对营养需求不同。对于马铃薯生产来说,合理的营养管理策略是应满足不同生长发育阶段的营养需求。
In the United States, Canada and other developed countries, potato nutrition management in line with the principle of reducing environmental pollution in order to obtain high yield, follow the best management practices BMP), to avoid unnecessary losses and waste due to excessive use of fertilizer. The amount of fertilizer needed by the potato is determined by its growth, growth stage, weather conditions and varieties. The amount of fertilizer applied is mainly based on soil availability, potential loss of fertilizer and crop potential (Dean, 2004). Different stages of growth and development on the nutritional needs of different. For potato production, a reasonable nutrition management strategy should meet the nutritional needs of different stages of growth and development.
