为了探讨稀土元素对茶叶的增产效应和施用技术,以便在生产上大面积推广提供科学依据,我场从1985年开始以六龄和二十三龄的梅占品种进行试验。试验区土壤属赤红壤,pH值4—5.1,土壤肥力较低,有机质含量少,严重缺磷。我们于各季茶芽开始萌发或一芽一叶初展时,分别喷施O.03％和0.05％浓度的稀土元素稀释液(每亩用河南商丘产硝酸稀土—含氧化物38.7％40或60克,年喷施3—4次)。对照区仅喷施清水。其结果如下: 1.促进茶芽早生快发,试验区春茶萌芽期比对照提早三天左右,各季茶比对照提早4— In order to explore the effects of rare earth elements on tea yield and application techniques in order to provide a scientific basis for the promotion of large-scale production, our field from 1985 to six and twenty-three age of the plum varieties tested. Soil in the experimental area is reddish soil, pH value 4-5.1, soil fertility is low, less organic matter, a serious shortage of phosphorus. We germinate at the beginning of each season bud or bud a leaf early exhibition, were sprayed with 0.03% and 0.05% concentration of rare earth elements diluted solution (per acre produced in Henan Shangqiu rare earth nitrate - oxide 38.7% 40 or 60 Grams, spraying 3-4 years). Control area only sprayed with clean water. The results are as follows: 1. To promote early buds of tea buds quickly, the test area spring buds three days earlier than the control, each season tea earlier than the control 4-
