选用角果抗裂性存在显著差异的2个油菜品种，于2012—2014年进行氮肥(0、90、180、270和360 kg N hm–2)、磷肥(0、60、120、180和270 kg P2O5 hm–2)、钾肥(0、75、150、225和300 kg K2O hm–2)用量对油菜角果抗裂性相关性状影响的单因素试验。结果表明，氮、磷、钾肥用量对油菜抗裂角指数的影响均呈波峰曲线变化，华双5号和华航901达最大抗裂角指数的纯氮用量分别为160 kg hm–2和140 kg hm–2、P2O5为120 kg hm–2和160 kg hm–2、K2O均为180 kg hm–2；油菜抗裂角指数的变化大小因肥料种类而异，氮、磷、钾3种肥料中，钾肥对抗裂角指数的影响最大；不同氮、磷、钾肥用量处理条件下，角果果壳重和植株株高的变化是影响油菜角果抗裂角性的重要因素，可作为初步、快速筛选油菜抗裂角种质资源的重要指标。

To study the effects of the farming measures on silique shatter resistance of rapeseed, we designed different fertilizer application combinations of N (0, 90, 180, 270, and 360 kg N hm–2), P (0, 60, 120, 180, and 270 kg P2O5hm–2) and K (0, 75, 150, 225, and 300 kg K2O hm–2) with two varieties for better machinery harvest. Results showed that with the increase of N, P and K fertilizer application rates, the silique shatter resistance index (SRI) of the two varieties changed as a multi-peak curve. The high-est SRI of Huashuang 5 was reached under application of 160 kg N hm–2, 120 kg P2O5hm–2 and 180 kg K2O hm–2, while that of Huahang901 was under application of 140 kg N hm–2, 160 kg P2O5 hm–2 and 180 kg K2O hm–2. The change degree in SRI differed due to different fertilizers, and K fertilizer had the greatest effect on the SRI of the two varieties among N, P and K fertilizers. The silique wall weight and plant height under different N, P and K fertilizer rates were the key factors affecting rapeseed’s SRI, and could be used as important indexes in silique shatter resistance screening.
