油菜在生长发育过程中，不仅需要吸收足够量的氨、磷、钾等大量元素，而且需要吸收一定量的棚、锌、铜、锰等微量元素。若这些微量元素摄入量不足，不可避免地导致相应的缺素症状，同时也会妨碍油菜对氮、磷、钾等大量元素的吸收，从而不利于油菜的正常生长发育。为此，我们于1 Rape in the process of growth and development, not only need to absorb a sufficient amount of ammonia, phosphorus, potassium and other large elements, but also need to absorb a certain amount of shed, zinc, copper, manganese and other trace elements. If these trace elements intake is insufficient, it will inevitably lead to the corresponding lack of symptoms, but also hinder the rape on nitrogen, phosphorus, potassium and other large elements of absorption, which is not conducive to the normal rape growth and development. To this end, we are at 1
