就我国多数茶区而言,春季是全年茶树新梢生长最旺,茶叶产量最高,质量最好的季节,因此,抓好春茶管理具有十分重要的意义。根据茶树春梢的生长特点,结合我国多数茶区的春季气候条件,春季茶园管理的主要内容是: 1.追施春肥:试验研究表明,春肥不但有助于春茶增产,而且对提高夏、秋茶产量也有良好的作用,施春肥的茶园与不施春肥的相比,全年增产达10~20%。春肥应以速效化学氮肥为主,氮肥用量应占全年追肥总氮量的40%左右。一般亩产干茶200~300斤的茶园,每 In terms of most tea areas in China, the spring season is the year with the most growth of tea shoots and the highest tea yield and the best quality. Therefore, it is of great significance to grasp the management of spring tea. According to the growth characteristics of tea tree spring shoots and the spring climatic conditions in most tea areas in our country, the main contents of spring tea garden management are as follows: 1. Pursuing spring fertilizer: Experimental research shows that spring fertilizer not only helps to increase yield of spring tea, Summer and autumn tea production also has a good effect, Shi Chunfei tea and non-spring compared to the full-year yield of 10 to 20%. Spring fertilizer should be based on quick-acting chemical nitrogen, nitrogen fertilizer dosage should account for about 40% of the total nitrogen fertilizer. General mu tea 200 ~ 300 pounds of dry tea, each
