一、引言建国以来,良种的推广,促进了农业生产。唯在良种保纯方法上,还缺少一种简而易行、行之有效的办法。农业合作化时,推行留种田制度,但常被农忙挤掉,进而搞种子复壮更新,收效也受到限制。种子的混杂,种性的退化,对农业生产带来了不利的影响。我们在长期工作中感到,就良种保纯方法而言,值得进一步探讨。

I. Introduction Since the founding of the People’s Republic of China, the promotion of fine varieties has promoted agricultural production. Only in the method of seed purification, there is still a lack of a simple and effective way. In the course of agricultural co-operation, the introduction of the farming-leaving system was often squeezed out by the farmers, and the rejuvenation of seeds was renewed and the results were also limited. Mixed seeds and the degeneracy of species have had a negative impact on agricultural production. In our long-term work, we feel that it is worth further exploring the method of seedbeds preservation.
