酸角嫁接技术研究

Study on grafting techniques of tamarindus

于2002-2004年在属干热河谷地区的元江坝进行以当地酸型酸角为砧木,泰国甜型酸角为接穗的酸角嫁接技术研究。结果表明:3种不同嫁接方法的嫁接效果无明显差异;嫁接季节以4月为宜,此时嫁接不但成活率高,而且可以当年出圃定植;选用1年生的砧木和接穗嫁接,其成活率较高;嫁接后7-10d进行第1次灌水,对于嫁接成活更为有利。研究结果对酸角的品种改良,良种扩繁和良种苗圃的建立具有重要的指导意义和应用价值,为早实、丰产、优质的酸角生产提供了技术支持。

In the experiment, the local acid type of tamarindus was used as anvil and the Thailand sweet type was used as cion, the grafting techniques of tamarindus were studied in Yuanjiang, a dry-hot river valley in 2002- 2004. The results showed that there was obvious difference on the effect of three grafting methods~ the suitable grafting time was Feb, for higher survival rate and fixed-planting in the same year. Moreover, the survival rate would be higher with one year aged anvil and cion; the first irrigating should be carried out in 7-10 days after grafting and would be good for the survival rate. This research would be of importance for directing variety improvement of tamarindus, reproduction and nursery foundation of good variety, and providing techniques to the production of earlier fruiting and maturing, high yield and fertility and good quality tamarindus.
