航天育种也称为空间技术育种或太空育种,就是指利用返回式航天器和高空气球等所能达到的空间环境对植物的诱变作用以产生有益变异,在地面选育新种质、新材料,培育新品种的农作物育种技术。航天育种主要分为三个步骤。首先是种子筛选,这一程序非常严格,需要专业技术。带上 Space breeding, also known as space technology breeding or space breeding, refers to the use of spacecraft such as return spacecraft and high-altitude balloon environment can mutagenic effect on plants to produce beneficial mutations in the breeding of new germplasm on the ground, new materials , Cultivate new varieties of crop breeding technology. Aerospace breeding is divided into three steps. The first is seed screening, a very rigorous process that requires specialized skills. Bring it
