不同氮水平对马铃薯块茎增长、产量和维生素C含量的影响
Effects of Different Nitrogen Application Rates on Tuber Bulking, Yield and Vitamin C Content of Potato
摘要
Abstract
The effect of different nitrogen application rates on tuber bulking,yield and Vitamin C content of potato were studied in field experiments. The results showed that compared with N0,potato tuber dry matter accumulation was increased from 42.8% to 91.59%by nitrogen treatments at harvest,nitrogen fertilizer application increased the yield of potato on the basis of phosphorus and potassium fertilizer,and yield was increased from 22.3% to 61.48%,excessive nitrogen fertilizer decreased vitamin C content at potato tuber of development later stage.关键词
