摘要： 摘要：为了探明超级杂交稻‘甬优12’产量与施有量关系，揭示其单季稻超高产栽培需肥规律，提升整体施肥技术水平，采用在统一栽培技术措施下测土配方施肥，跟踪调查2012—2013年12个示范方不同施肥组合及施肥量，以专家组实割实收考查产量的方法，对单季稻甬优12’施肥量与产量关系及超高产栽培施肥技术进行研究。结果表明，在土壤肥力水平中等的情况下，单季晚稻‘甬优12’产量(Y)随施肥量（有机肥F和N、P、K）增加而递升且呈幂次函数（近似线性）递升，其关系模型为：Y=0.00003F2-0.2963F 11302 (Y=0.2301F 9258)，Y=0.0504N2 24.566N 1953(Y=51.243N-1543)，Y=0.0361P2 26.596P 8707(Y=34.143P 8358)，Y=0.0208K2 7.4996K 8499(Y=17.793K 7306)。由此提出11000~12000 kg/hm2目标产量为投入农家有机肥8000~12000 kg/hm2、纯N量245~265 kg/hm2、P2O5量75~105 kg/hm2、K2O量210~265 kg/hm2，N:P:K比例1.00:0.35:0.93；目标产量15000 kg/hm2为投入农家有机肥15000~20000 kg/hm2、纯N量320 kg/hm2，P2O5量190 kg/hm2，K2O量410 kg/hm2，N:P:K比例1.00:0.59:1.28。后者生产成本大幅度提高，生产风险大幅度上升，需集成超级栽培、肥料运筹、病虫防治、水桨管理等一系列协调促进，才能实现预期目标。

Abstract: Abstract: In order to study the relationship between fertilization level and yield of ‘Yongyou 12’, Reveal the single cropping rice super high yielding cultivation fertilizer needed regularity, improve the overall level of fertilization technology , Used in the unified cultivation technology measures of formula fertilization by soil testing, tracking survey 12 demonstration of different fertilizer combinations and the amount of fertilizer from 2012 to 2013 , to the expert group paid real cutting method to examine production, research on single cropping rice ‘Yongyou 12’fertilization and yield relationship and super high yield cultivation technique of fertilization. The results showed that, under moderate soil fertility levels, the yield (Y) of ‘Yongyou 12’ was accelerated with the increase of fertilizer application, according with the power function shown as Y=0.00003F2-0.2963F 11302 (Y=0.2301F 9258), Y=0.0504N2 24.566N 1953 (Y=51.243N-1543), Y=0.0361P2 26.596P 870 (Y=34.143P 8358), Y=0.0208K2 7.4996K 8499 (Y=17.793K 7306). Based on the function, the paper summarized a fertilizer combination for ‘Yongyou 12’ to obtain yield to 11000-12000 kg/hm2 was organic fertilizer 8000-12000 kg/hm2, nitrogen (N) 245-265 kg/hm2, phosphor (P2O5) 75-105 kg/hm2 and potassium (K2O) 210-265 kg/hm2. The structure of N, P, K ratio was 1.00:0.35:0.93. Another fertilizer combination for ‘Yongyou 12’ to obtain yield to 15000 kg/hm2 was organic fertilizer 15000-20000 kg/hm2, nitrogen (N) 320 kg/hm2, phosphor (P2O5) 190 kg/hm2 and potassium (K2O) 410 kg/hm2 with the structure of N, P, K ratio was 1.00:0.59:1.28, which production costs and risk increased remarkably. For living up to the expectations, a series of coordination measures were suggested including super cultivation, fertilizer application, water management and control of diseases and pets.
