为了探索不同种类磷钾肥对优质杂交油菜主要品质性状和产量的影响,指导优质杂交油菜生产,采用田间试验方法,比较了不同种类磷、钾肥料与黔油29号品质性状及产量的关系。结果表明:统一施用氮肥的条件下,增施磷、钾肥均可改善黔油29号植株性状、增加一次有效分枝、单株有效角果数和每角粒数;在试验范围内,油菜产量随着施用磷钾肥用量的增大而增加;施用不同种类磷钾肥对黔油29号的芥酸、硫苷、含油量和粗蛋白含量的影响均不显著。
In order to explore the effects of different types of P and K fertilizers on the main quality traits and yield of high quality hybrid rapeseed, and to guide the production of high quality hybrid rape, the relationship between different types of phosphorus and potassium fertilizers and the quality traits and yields of Qianyou 29 was compared. The results showed that under the condition of uniform application of nitrogen fertilizer, the application of phosphorus and potassium fertilizer could improve the plant traits of Qianyou 29 and increase the number of effective pods and the number of effective pods per plant. In the experimental range, the yield of rape With the increase of the amount of P and K fertilizer application, the application of different types of P and K fertilizers had no significant effect on the content of erucic acid, glucosinolate, oil content and crude protein in Qianyou 29.
