特种用途皂荚优良无性系选择研究

为解决皂荚生产上存在的没有工业原料专用良种的问题,在枣庄、邹城、临沂等地现存的3万余株20~300年生皂荚大树中,筛选出优良单株4株,分别在山亭区、峄城区、滕州市、市中区等地进行生长量、产量、适应性、稳定性比较试验。综合分析,选择出工业原料用羊肠子、多刺速生、长荚、早丰等4个优良无性系,其产籽量超过对照48.3%~142.5%,其它指标优于对照。

Special purpose Gleditsia sinensis good clone choice research

In order to solve the problem that produces esists no sepecial - purpose good variety for industry among Gleditsia sinensis , there is growing in 20- 300 ages more than 30,000 Gleditsia sinensis in Zaozhuang, Zou cheng, Linyi ,we choose 4 good individuals separately in Shahring district, Yicheng district , Tengzhou city ,central carny on development growth quantity, fruit weight, survivability, stability comparison test. Generalized analysis, we choose the raw material for industry fast- growing with Yangchangzi ,Duocisusheng, Changjia,Zaofeng and so on 4 fine clones, it produces the seed quantity to surpass compares 48.3% - 142.5%, other economical characters surpass the comparison.
