近几年以来,我国各地在农作物良种“提纯复壮”方面做了大量的工作,对于农业生产起到了良好的效果,成绩是可喜的。但有些农业科技人员,对于良种“提纯复壮”,这个概念和方法,认识不足。如:有的将“提纯复壮”方法误认为是“系统选种”方法;有的拿不准选种的标准,年年选年年杂等,走 In recent years, a great deal of work has been done in the areas of “purification, rejuvenation” of crop varieties in various parts of China, and good results have been achieved for agricultural production. The results are gratifying. However, some agricultural scientists and technologists are not well aware of the concept and method of “purifying and rejuvenating” elite seeds. Such as: Some will be “pure and rejuvenation” method mistaken for the “systematic selection of” methods; some are not allowed to choose the standard of selection year after year, etc.
