我省乌桕良种资源丰富,优株选择的潜力相当大。为提高乌桕良种化水平,自1979年起,我们在省乌桕科研协作组的统一组织下,以浙江省林业局1979年8月编写的《林木良种资源普查技术参考资料》中的乌桕选优标准为依据,在全省范围内开展乌桕选优工作。目前初、复选阶段的工作业已完成。现根据我们在乌桕选优过程中碰到的一些具体问题谈点看法。 There are plenty of elite varieties in our province, and the potential for elite selection is considerable. In order to improve the level of Achnatherum splendens, since 1979, under the unified organization of the Collaborative Research Group of Aridae in the province, we selected the best selection criteria of “Ancestral Forest Resources” in August 1979 by Zhejiang Forestry Bureau As the basis, in the province to carry out Wuyi election work. At present, the work of the check phase has been completed. We are going to talk about some specific issues that we encountered in the process of selecting and merciless voters.
