通过以前的试验和生产实践证明,氮素对油菜的生长发育与产量形成的影响甚大,但对其生育过程中的氮代谢报道不多,尤其是杂交油菜对氮素的效应如何,目前更无资料。本试验试图在大田条件下探讨不同油菜品种(组合)在不同氮素水平下的生长发育、产量形成,及其与氮代谢的相互关系,为促进油菜生产的合理施肥提供一定的科学依据。
Previous experiments and production practices have proved that nitrogen has a great influence on the growth and yield formation of rapeseed but little is reported about its nitrogen metabolism during its growth, especially the effect of hybrid rape on nitrogen. data. In this experiment, we tried to explore the growth and development, yield formation and the relationship between nitrogen metabolism and rapeseed (rapeseed) cultivars at different nitrogen levels under field conditions in order to provide some scientific basis for promoting rational fertilization of rapeseed production.
