通过对华杂3号油菜的氮、磷、钾、硼施用量的研究,找出了对华杂3号油菜产量影响较大的试验因子是亩施氮量、施磷量和施硼量。并利用频数分析法,通过计算机模拟寻优,建立了华杂3号油菜在淮南稻区亩产200kg以上的优化施肥模型及N、P、K、B适宜用量分别为纯N12.5~13.7kg/亩、P2O56.4~7.4kg/亩、K2O11.9~13.9kg/亩、B1.08~1.27kg/亩。
Through the research on the application of nitrogen, phosphorus, potassium and boron in Huaza No.3 rapeseed, it was found that the most influential factors for the yield of Huaza No.3 were yield of nitrogen, phosphorus and boron. The optimal fertilization model of Huazha No.3 oilseed rape over 200kg per mu in Huainan rice planting area was established by means of frequency analysis and optimization by computer simulation. The optimum dosage of N, P, K and B was pure N12.5 ~ 13 respectively. 7kg / mu, P2O56.4 ~ 7.4kg / mu, K2O11.9 ~ 13.9kg / mu, B1.08 ~ 1.27kg / mu.
