合理施肥是提高作物产量的重要手段之一,而合理施肥又必须以作物需肥规律为基础。国内外对油菜的营养特牲及需肥规律都曾进行过许多研究,但对于甘蓝型春油菜的需肥特性及施肥技术的研究却涉及甚少。为此,我们针对引种甘蓝型春油菜成功以后,进一步探讨其高产栽培技术,1978-1983年在高寒阴湿地区进行了奥罗油菜需肥规律及合理施肥技术的研究。 Rational fertilization is one of the important means to increase crop yield, and fertilization must be based on the principle of crop fertilizer. At home and abroad, many researches have been done on the nutrition of rapeseed and the rule of needing fertilizer. However, little is known about the fertilization characteristics and fertilization technology of Brassica napus. Therefore, after the success of the introduction of the cabbage spring rape, we further discussed its high-yielding cultivation techniques. During 1978-1983, we studied the rule of fertilization and fertilization in Olea europaeus in cold and humid areas.
