《农业科学与技术(英文版) 》 2008
摘要：The aim of the study is to investigate the absorption laws of nitrogen,phosphorus,and potassium,and proper nitrogen application in Chuanxiangyou 9838 under no-tillage cultivation. Five nitrogen application treatments were designed to analyze the absorption laws of N,P and K,and to discuss the effects of different N fertilizer application amounts on yield and yield composition factors of Chuanxiangyou 9838. The results showed that gross nutrient absorption in Chuanxiangyou 9838 was greatly varied at differen...
