台地茶与大树茶（Platform tea and big tree tea） 1. tea varieties: Tableland Tea mostly artificial breeding varieties, in order to maintain the varieties of pure lines by asexual reproduction, this small variation of tea, tea quality and trees are similar, but the resistance is weak, every year must fight against the invasion of pests and pesticides, pesticide and light dose effect is poor, it will lead to heavy doses of pesticides the pesticides residues, we seldom meet together. The tree of tea for the local population, but the variation of strong resistance, and dispersed in the forest growth and application difficulties, almost no Dayao, dont worry about the pesticides residues, more healthy. 2. ways of planting: 1 square meters of Tableland Tea growing N tree, because the unit area of soil available nutrients is limited, resulting in a small area in the Tableland Tea intense competition for nutrition, and asexual propagation of Tableland Tea without root, only the side of the root (commonly known as crab root), root buried shallow; the sexual reproduction of Tableland Tea is a root, but by the artificial control of dwarf tea and tea plant height, root growth is proportional to the crown, so the root depth is shallow, cannot be absorbed into deeper soil nutrient. Therefore, terrace tea must be fertilized to ensure the nutrient supply of tea tree. Chemical fertilizers are divided into two categories: organic and inorganic fertilizers, which play a decisive role in improving the yield of tea. Ordinary tea to apply inorganic fertilizer, mainly nitrogen fertilizer, but if a large number of long-term use, will make the soil plate hard, physical deterioration, caused widespread deterioration of soil in tea garden, the formation of tea can give important nutrients to reduce, reduce or even damage the quality of tea, tea, tea seedling growth caused by death; organic tea garden to apply organic fertilizer, application of natural organic fertilizer can make tea shoots and crude fib
