天津农学院园艺系赵惠祥副教授等人经过12年的精心研究和试验,采用组织培养的方法培育出耐盐碱树种——珠美海棠。经有关专家鉴定,这项科研成果填补了国内空白。珠美海棠(Malus Zumi)在含盐量0.5%～0.6%的土壤中仍能正常生长,其耐碱能力与柽柳相近。该树种既可作一般绿化树种栽植,又可作嫁接苹果树的的砧木,为盐碱地区的绿化和发展果树生产,开创了新路。我们于1992年6月下旬在寿光县东埠乡林场进行了珠美海棠盐碱地全光喷雾嫩枝扦插育苗试验。以当年生枝条分上、中、下三部分作插穗,长5～8cm,上部保留一片叶。插穗经
Horticultural Department of Tianjin Agricultural College, Associate Professor Zhao Huixiang et al. After 12 years of careful research and experimentation, the use of tissue culture methods to cultivate a salt-tolerant species - Begonia Begonia. The experts identified, the scientific research to fill the gaps. Malus Zumi still grows normally in soils with salt content of 0.5% ~ 0.6%, and its alkali tolerance is similar to that of Tamarix. The tree species can be used for planting green trees in general, but also for grafting apple tree rootstocks, creating a new road for the greening of saline-alkali areas and the development of fruit trees. In late June 1992, we conducted a full-lumen shoot shoot propagation experiment of Begonia tuberosus L. in Dongbu Township, Shouguang County. In current year branch points, middle and lower part of the cuttings, length 5 ~ 8cm, the upper part of a leaf. Cuttings by
