| 摘要：对云南省元江干热河谷引进的泰国甜角开展嫁接繁殖技术探讨，结果表明嫁接措施、嫁接时间、切砧高度、砧木类型、砧木龄级、接穗年龄、接穗位置和天气条件等因子对嫁接成活率有明显作用。嫁接措施宜采用技术简单、操作方便的切接法，其平均成活率75。0%~76。4%；嫁接时间宜选在3~4月；用半年生切砧苗作砧木，切砧高度在20~40 cm比较适合；接穗的位置效应明显，宜选1年生枝的基部和中部枝段，带1~2个腋芽的穗段为优；此外，天气状况对嫁接成活率也有显作品用，泰语论文题目，以阴天或雨后晴天嫁接为宜。采用常规管理技术，嫁接后3个月可育成甜角嫁接苗进行造林。 Abstract：On the dry hot valley of Yuanjiang, Yunnan Province, the introduction of sweet Thai tamarind carry out grafting propagation technology research. The results showed that grafting methods, grafting time, cutting factor anvil height, stock types, stock age, age of scion and scion location and weather conditions on grafting survival rate have the obvious influence. Grafting method should adopt the technique is simple and easy to operate, and the average survival rate is 75. 0%~76. 4%; grafting time should be selected in 3 ~ 4 months, half a year cut anvil seedling rootstock, rootstock height in 20-40 cm is suitable for; scion position effect obviously, should choose one year old branches basally and middle stem segment, with 1 or 2 axillary buds of ear section is better; in addition, weather conditions on the grafting survival rate also significantly affected, preferably in cloudy or sunny after rain grafting. In the 3 months after grafting, the seedlings of sweet angle were grafted with the conventional management technology. 引言：泰国甜角属苏木科(Caesalpiniaceae)酸豆属(TamarindusLinn.)的一种常绿大乔木,为酸角(Tamarindus indicaLinn.)的一类甜型品种,目前在泰国已广泛种植,是一种传统水果,其成熟果实味甜,泰国每年都要向欧洲及东南亚其它国家出口大量的果实[1].泰国甜角果肉中含总糖、还原糖、粗 ，泰语论文范文 |
