本刊从1987年第6期开始连续介绍茶树新品种,到本期为止,已将全国茶树良种审定委员会1987年元月认定的22个茶树新品种介绍完毕,使大家对这些品种的主要性状和栽培特性有所了解,可作为今后在引种栽培中的参考。为了更有效地进行茶树新品种引种工作,还需要注意以下5个问题。第一,选配品种要考虑到当地的生态条件。不同的茶树品种具有不同的生态特性,其中气温条件尤为关键。如果引种地区的生态条件超越品种的适应范围,就不能使良种充分表现其优良特性,甚至使引种失败而造成严重经济损失。从品种的生态类型来看,大叶品种比中小叶品种的抗寒力弱,象英红1号和云抗10、14号等品种只适于年有效积温>5500℃、无霜期>300天和极端低温高于-3℃的华南和西
Since the sixth issue of 1987, the journal has continuously introduced new varieties of tea trees. By the end of this issue, 22 new varieties of tea trees identified by the National Tea Tree Species Approval Committee in January 1987 have been introduced, so that the main characters of these varieties, Cultivation of some understanding, can be used as a reference in the introduction of cultivation in the future. In order to carry out the introduction of new varieties of tea tree more effectively, you also need to pay attention to the following five questions. First, matching varieties to take into account the local ecological conditions. Different varieties of tea have different ecological characteristics, of which the temperature conditions are particularly critical. If the ecological conditions of the introduced area exceed the adaptability of the varieties, the fine varieties can not be allowed to fully display their excellent characteristics, and even the introduction fails to cause serious economic losses. From the ecotypes of cultivars, the cold-resistant ability of large-leaved varieties is lower than that of middle and small-leaf cultivars, and the varieties such as Yinghong 1 and Yunkang 10 and 14 are only suitable for the annual effective accumulated temperature> 5500 ℃, frost-free period> 300 days and Extreme low temperature higher than -3 ℃ South China and West
