茶树在阜平山区的引种适应性和扦插繁殖研究

采用4个不同茶树品种（‘龙井43’、‘龙井长叶’、‘茂绿’、‘鸠坑早’）在河北保定阜平山区通过塑料大棚栽培，对其越冬抗寒适应性进行比较分析，研究茶树在该地区引种的可能性，同时对抗寒性较强的‘龙井43’进行了扦插繁殖研究。结果表明，在河北保定阜平山区海拔200~2000 m、年平均气温12.7℃，年平均降水量680.5 mm，无霜期约180天的地区，不同品种的抗寒性和适应性存在较大差异。‘龙井43’在塑料大棚内能安全越冬，越冬率达95%以上，生长发育正常，且表现出良好的适应性。其次为‘龙井长叶’、‘茂绿’，‘鸠坑早’抗寒性最差。由此可见，在阜平山区，采用塑料大棚保护，选择合适品种进行茶树栽培是可行的。扦插研究结果显示，不同基质对‘龙井43’的扦插生根影响不同，泥炭+珍珠岩效果最佳，生根率达86.2%；另外，不同激素种类、浓度和处理时间对扦插生根的影响不同。

Study on Adaptation of Introduction and Cutting Propagation of Tea in Fuping Mountainous Region of Hebei Province

In the paper 4 different varieties of tea （‘ Long- Jing 43＇, ‘ Long- Jing Changye＇, ‘ Mao- Lv＇ and ‘Jiu-Keng zao＇） were used to study the feasibility of expanding south tea into Fuping mountainous region of Hebei Province. Moreover, the cutting propagation was conducted to ‘Long-Jing 43＇ with stronger cold resistance. The results showed that there was a big difference among different varieties of cold resistance and adaptability in Fuping mountainous region of Hebei Province where elevation ranges 200-2000 m, annum average temperature ranges 12.7℃, and precipitation ranges 680.5 mm. ‘ Long-Jing 43＇ developed normally, could survive safely and showed good adaptability in plastic greenhouse. Followed by ‘ Long-Jing changye＇ and‘Mao-lv＇. The cold hardiness of ＇Jiu-Keng zao＇ was the worst. Thus it can be seen that it was feasible to cultivate tea by selecting appropriate varieties in plastic greenhouse in Fuping mountainous region of Hebei Province. The study of cutting propagation showed that the influence was different among the different cutting soils to ‘Long-Jing 43＇. Peat supplemented with perlite was the best which the rooting rate was 86.2%. In addition, the effects of different types, concentrations and treatment times of hormone were different to rooting rate.
