１９８８～１９９１年在河南油菜产区进行了该项试验。结果表明：每生产１００ｋｇ油菜籽需吸收Ｎ、Ｐ２Ｏ５、Ｋ２Ｏ分别为７．６、２．９、７．３ｋｇ，并表现为前期吸收氮肥多，后期吸磷钾高。氮、磷、钾运转率分别为５１．０％，６３．４％，２２．７％。在中等肥力地块，施氮增产２２．０％～６０．２％，最佳施氮量为１５．６ｋｇ。单施氮、磷不如氮磷或氮磷钾配合施用效果好。施氮增加了粗蛋白含量，降低了粗脂肪含量，施磷、钾肥提高油酸、亚油酸含量，降低芥酸含量.
1988 to 1991 in Henan rapeseed areas conducted the test. The results showed that N, P2O5 and K2O needed to be absorbed by each 100kg rapeseed were 7.6, 2.9 and 7.3kg, respectively. The results showed that nitrogen fertilizer was more absorbed in the early stage and phosphorus and potassium were higher in the late stage. The operation rates of nitrogen, phosphorus and potassium were 51.0%, 63.4% and 22.7% respectively. In moderately fertile land, nitrogen application increased 22.0% -60.2% and nitrogen application rate was 15.6kg. Nitrogen, phosphorus than nitrogen or phosphorus or NPK with a good effect. Nitrogen fertilizer increased crude protein content, reduced crude fat content, applied phosphorus and potassium fertilizer increased oleic acid, linoleic acid content, reduced erucic acid content.
