对临海市2012-2013年12个甬优12单季稻高产示范方的施肥水平与产量的关系进行了分析。结果表明，在土壤肥力水平中等的情况下，单季晚稻甬优12的产量（Y）随施肥量（有机肥F和N、P、K）的增加而递增，且呈幂函数关系。由此提出11000~12000 kg/hm2目标产量方案为：每hm2投入农家肥8000~12000 kg、纯N 245~265 kg、P2O575~105 kg、K2O 210~265 kg，N∶P∶K为1.00∶0.35∶0.93；目标产量15000 kg/hm2的方案为：每hm2投入农家肥15000~20000 kg、纯N 320 kg、P2O5190 kg，K2O 410 kg，N∶P∶K为1.00∶0.59∶1.28。%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.
