为了进一步探索楸树扦插育苗技术,本所在1982年取得硬、软枝扦插育苗成功的基础上,近两年来又突破了埋条、单芽和叶片扦插育苗关.其中埋条150根,生根部位达256处,成苗188株;单芽扦插平均愈合率为99%,生根率为95%,成苗率为88%;叶片扦插平均愈合率为82.9%,最高组合达96%,平均生根率为53%,最高组合达96%,现将试验结果总结如下:埋条(一)插壤准备取山地棕壤与清水沙1:1相混合,投放入以砖砌成的扦插池中,深度50厘米,以3‰高锰酸钾液消毒备用.(二)种条剪切
In order to further explore Catalpa bracteatum seedling technology, we made hard and soft branch cutting nurturing in 1982, based on the success of the past two years, breaking through the buried strips, single shoots and leaf cutting and nursery clearance. Including 150 embedded roots, rooting site The average root healing rate was up to 256, and the number of mature seedlings was 188. The average healing rate of single cutting was 99%, the rooting rate was 95% and the seedling rate was 88%. The average healing rate of cutting was 82.9% Is 53%, the highest combination of up to 96%, the test results are summarized as follows: Buried (a) soil preparation to take the mountain brown earth and clear water mixed 1: 1, put into the brick into the cuttings pool depth 50 cm to 3 ‰ permanganate disinfection reserve. (B) species of cut
