Abstract

Field experiment of fertilizer effect was conducted in Wuxie.The results showed that nitrogen was the key factor in controlling grain yields of Lian-you 3419,and phosphorus was the second,potassium was the same important as phosphorus.The fertilizing amount to get the maximum grain yield was 194.80 kg N·hm-2,103.25 kg P·hm-2,115.58 kg K·hm-2.The most economical fertilizing amount was 160.09 kg N·hm-2,86.56 kg P·hm-2,88.73 kg K·hm-2.
