针对我省油菜单产底的状况，在我省二种主要稻田土壤上进行了氮磷钾硫硼肥配施对油菜效应及养分况状的研究。结果表明：①稻田种植油菜，由于水改旱的变化，使土壤有效态磷、硼含量降低，导致土壤严重缺磷、硼，这是致使稻田种油菜底产的主要原因。②油菜吸收氮、磷、钾养分主要在盛花期以前，分别占总吸收量的９２％，７９％、８９％左右。而硼、硫在盛花期后吸收量分别占总吸收量的５０％，３６％左右，说明氮、磷、钾肥应早施，着重为基肥和越冬肥，而硼肥应以基施为主，部分追喷施为好。
Aiming at the situation of the end of oilseed production in our province, the effect of nitrogen, phosphorus, potassium, sulfur and boron fertilizers on rapeseed performance and nutrient status was studied in the two main paddy soils in our province. The results showed that: (1) The rapeseed planting in paddy field reduced the effective phosphorus and boron content of soil due to the change of drought, which resulted in serious phosphorus and boron deficiency in the soil. (2) The nutrient absorption of nitrogen, phosphorus and potassium in rape mainly occupied 92%, 79% and 89% of the total absorption before the full flowering period respectively. The boron and sulfur absorption after the full bloom accounted for 50% of the total absorption, 36%, indicating that nitrogen, phosphorus and potassium fertilizer should be early, with emphasis on basal and overwintering fertilizer, and boron fertilizer should be based facilities, Part of the chase spray as well.
