Abstract
The relationship between fertilization level and yield of Yongyou 12 were investigated during 2012 and 2013 in Linhai County in this paper. The results showed that the yield of Yongyou 12 was accelerated with the increase of fertilizer application under moderate soil fertility levels. Based on the function, a fertilizer combination for Yongyou 12 to obtain yield of 11 000~12 000 kg/hm 2 was organic fertilizer 8 000~12 000 kg/hm2, nitrogen (N) 245~265 kg/hm2, phosphorus (P2O5) 75~105 kg/hm2 and potassium(K2O) 210~265 kg/hm2. The structure of N, P, K ratio was 1.00∶0.33∶0.92. Another fertilizer combination for Yongyou 12 to obtain yield of 15 000 kg/hm2 was organic fertilizer 15 000~20 000 kg/hm2, nitrogen (N) 320 kg/hm2, phosphorus (P2O5) 190 kg/hm2 and potassium (K2O) 410 kg/hm2, and the structure of N, P, K ratio was 1.00∶0.59∶1.28.关键词
