微量元素在植物中含量极少,但对植物的正常生长发育,和氮、磷、钾等大量元素一样,也是不可缺少的。它们在植物生理活动中有其特定的功能,对植物的光合作用和碳水化合物的转运、积累,有着密切的关系。为了摸清微量元素对香樟幼苗生长的影响,快速培育优质壮苗,岳阳地区林科所曾于1980年7—10月,进行了硼、铁、锰、钼四种微量元素根外施肥的对比试验。
Trace elements in the plant content is minimal, but the normal growth and development of plants, and nitrogen, phosphorus, potassium and other large elements, it is also indispensable. They have their specific functions in plant physiological activities and are closely related to photosynthesis and transport and accumulation of carbohydrates. In order to find out the effect of trace elements on the growth of camphor seedlings and quickly cultivate high-quality seedlings, Linke in Yueyang Prefecture conducted the external application of four kinds of microelements of boron, iron, manganese and molybdenum from July to October in 1980 Comparative Test.
