三叶青藤特性及苗木繁育技术研究

Study on the features and reproductive techniques of Illigera rhodantha Hance

在3、5、7、9、11月五个月份采集三叶青藤二年生茎藤,分别用北京产双吉尔GGR6号生根粉50 mg.kg-1浸泡2小时进行扦插试验;用随采随播、5天后播种、10天后播种、15天后播种、20天后播种五种方法进行种子发芽试验。结果表明,扦插育苗试验时五个月份的生根率分别是79.2%、82.8%、69.6%、62.4%、44%;种子育苗时五种处理的发芽率分别是96%、79%、57%、20%、11%。5月份扦插育苗效果最好,生根率达到82.8%;播种育苗时随采随播的效果最好,发芽率达到96%;在生产上采用扦插育苗会有更多的优势。

Cutting biennial woods were picked in March, May, July, September, November, soaking them 2 hours by powder No. GGR6 50 mg. kg-1 that produced Beijing shuangjier, then the raise seedling test was processing~ For seed germination test used with the method sowing immediately after collecting seed, sowing in fifth day after collecting, sowing in tenth day after collecting, sowing in fifteenth day after collecting, sowing in twentieth day after collecting. Result The rooting rate of cutting propagation test in five months was79.2%, 82.8%, 69.6%, 62.4%,44%, Germination rate of seed propagation in five kinds of treatment was 96%, 79%, 57%, 20%, 11%. The best cutting effect in May, the rooting rate was 82.8%.The best germination rate When planting seedlings with sowing immediately after collecting seed, the germination rate was 96%. Cutting propagation used in production will have more advantages.
