1.加强茶树氮素营养,能促进茶树嫩枝的萌发伸长及改变了年周期中嫩枝在各时期的发生的输迴次数,使后期产量增多,从而也提高了全年茶叶的总产量。 2.加强氮素营养提高了嫩枝中含氮化合物和水分含量,从而使营养生长旺盛,嫩枝叶片数增多,叶面积扩大,持嫩性加强,有利于提高制茶原料品质。 3.制茶原料品貭优劣是茶树品种、采摘、气候、土壤和施肥等多种因子的综合结果,在同一地区,相同栽培条件下,合理施用氮肥,既可提高茶叶产量,也可提高茶叶品貭。 4.选择适宜的氮肥品种和采用适宜的氮肥用量(亩施纯氮20斤),注意氮磷配合和分次施用,可以提高茶树对氮的利用率。 1.To enhance the nitrogen nutrition of tea tree, it can promote the elongation of young shoots of tea plants and change the number of translocation of shoots in each period during the annual cycle, so that the yield of later period increased, which also increased the total output of tea . 2. To enhance nitrogen nutrition to improve the nitrogen compounds and moisture content of shoots, so that vegetative growth, increased number of branches and leaves, leaf area expanded, holding tenderness to strengthen, is conducive to improving the quality of tea raw materials. 3. Tea raw materials 貭 pros and cons of tea varieties, picking, climate, soil and fertilization and other factors combined results in the same area, the same cultivation conditions, the rational use of nitrogen can not only improve the yield of tea, but also improve Tea products 貭. 4. Select the appropriate nitrogen fertilizer varieties and the use of appropriate amount of nitrogen fertilizer (Mushi Shi 20 pounds of pure nitrogen), pay attention to nitrogen and phosphorus with graded application, can improve tea utilization of nitrogen.
