以往的试验结果业已查明,微量元素对植物来说是必需的,也是有效的。在这些微量元素中锰具有最重要的作用,因此,它在农业生产中的应用也最广泛。关系粮食、蔬菜及果树等作物施锰肥的问题研究工作做得很多,但是,关于茶树施锰肥的问题研究得还很少。目前,虽也做了一些试验,但各研究工作者所得出的,关于锰肥在茶园中的增产效果是很不一致的。有关这个问题以后还必须进一步进行试验,以求彻底解决。 Previous experimental results have identified that trace elements are necessary and effective for plants. Manganese plays the most important role in these trace elements and therefore has the widest application in agricultural production. Much has been done about the research on the application of Mn fertilizers to crops such as grain, vegetables and fruit trees. However, there have been few studies on the problems of tea manure fertilizers. At present, although some experiments have been done, the results obtained by various researchers about the yield increase of manganese fertilizer in tea gardens are very inconsistent. There must be further experiments on this issue in the future in order to completely solve it.
