花棒(细枝岩黄蓍、中尾梢、花柴)是我省沙区的主要灌木之一,近几年我省已建成花棒采种基地。为得到播种品质好的种子,保证花棒种子在收购、调拨、使用中避免因劣质种子而造成损失,因此,必须制定一个合理可行的质量分级标准。为此,我们进行了这项工作。一、材料来源及检验方法 1、材料来源制定本标准所用的材料,收集于我省花棒的主要产区张掖、武威两地区1982年至1987年 Huanghuabian (twig Yarrow, middle tail, firewood) is one of the main shrubs in the sand area in our province, in recent years, our province has built a base of hibiscus seed. In order to get seeds of good sowing quality and ensure that the spent stem seeds can avoid losses caused by inferior seeds in the process of acquisition, allocation and use, a reasonable and feasible quality grading standard must be formulated. To this end, we conducted this work. First, the source of materials and test methods 1, the source of the material The material used in the development of this standard, collected in the main producing areas of Shaanxi Province, Zhangye, Wuwei two areas from 1982 to 1987
