在讲授达尔文主义基础讲到“米丘林学说基本原理”的第七个原理“杂交提高生物的生活力”的时候,内容中曾提到“品种内杂交能提高生活力”的问题:如果让同一种内的不同植株进行交配,可以提高生物的生活力。为了使同学深刻理解这个理论,我们曾通过“米丘林小组”做“向日葵的人工辅助授粉”实验,在我们的学校里,今年为了响应政府号召:增加油料作物的生产,种植了大批向日葵,可以
While teaching Darwinism about the seventh principle of “the basic principles of the Michurin doctrine”, “hybrids improve the viability of living beings,” we mentioned the issue of “crossbreeding within a variety of breeds can increase vitality.” Mating different plants within the same species can increase the viability of the organism. In order to make our students understand this theory deeply, we conducted “artificial sun-assisted pollination” experiments with the “Michurin Group”. In our school, in response to the government’s call this year to increase the production of oil crops and plant a large number of sunflowers, can
