茶树新梢的萌发和生长,在我省各茶区一般从3月上、中旬开始至10月中、下旬止,全年有效生长期为240天左右。在此期间,新梢多轮次的萌发生长,采茶也连续多批次进行。因此,在茶叶高产、稳产、优质综合技术措施中,合理施肥,及时补给营养就显得特别重要,收效也最明显。 一、茶树需肥特点和肥料种类 种茶的目的是为了采摘茶叶(新梢),加工成红、绿茶,以供社会需求。据分析,每百斤茶(鲜叶)中,含有氮素1.2～1.4斤,磷素0.2～0.23斤,钾素0.33～0.43斤。显然,N、P、K三要素中,氮素营养
Tea shoots germination and growth in the tea district in our province generally from March onwards, mid-October until mid-late, only the effective annual growth period of about 240 days. In the meantime, the new shoot many rounds of germination and growth, picking tea is also carried out in batches. Therefore, in the tea yield, stable yield, high-quality comprehensive technical measures, rational fertilization, timely nutrition is particularly important, the most obvious effect. First, tea needs fertilizer characteristics and types of fertilizer The purpose of tea is to pick tea (new shoots), processed into red, green tea for social needs. According to the analysis, each hundred pounds of tea (fresh leaves), containing 1.2 to 1.4 kg of nitrogen, 0.2 to 0.23 kg of phosphorus, potassium 0.33 to 0.43 kg. Obviously, N, P, K three elements, nitrogen nutrition
