氮、磷、钾等大量营养元素对茶树生长、产量与品质的关系以及施用的必要性,早已引起人们重视和得到普遍推广。但茶树对硼、锰、钼、铜、锌等元素的营养需要主要是20世纪才发现的,只有几十年的历史。同时茶树体内这些元素含量很少,对这些营养元素的需要量也只有氮、磷、钾的几百分之一到几万分之一,数量上少得多,可是它对茶树的生理生化、正常生育与产量品质关系很大。这种含量极少,作用又大是应用近代先进科学仪器才被
The large amount of nitrogen, phosphorus, potassium and other nutrients on the growth of tea, the relationship between yield and quality and the necessity of the application, has drawn great attention and has been widely promoted. However, the nutritional requirements of the tea tree for elements such as boron, manganese, molybdenum, copper and zinc are mainly discovered in the 20th century only for several decades. At the same time, the content of these elements in the tea tree is very little, and the requirements of these nutrients are only a few hundredths of the nitrogen, phosphorus and potassium to one in ten thousandths, the quantity is much less, but its physiological and biochemical, Normal birth and yield quality has a great relationship. This content is very small, the role of large and modern application of advanced scientific instruments was
