随着“神六”载人飞船安全返回地面,市场上出现许多贴着“太空”、“航天”标签的农业种子,说种植“航天种子”可以增产增收。日前,有关农业专家提醒,要科学地看待航天育种,不要神化和迷信,更不能乱贴“太空”标签。农业专家介绍,航天育种是指将植物种子搭载于返回式航天器,利用空间磁场、失重、辐射等环境因素,使种子基因发生突变,在返回地面后,通过育种专家的精心培育从中挖掘优良丰产新品种,从而显著提高农作物产量和品质。由于太空环境的复杂性以及种子个体对环境的适应程度的不同,并非进入太空的每粒种子都会
As the “Shenzhou VI” manned spacecraft returns to the ground safely, many agricultural seeds bearing “space” and “aerospace” labels appear on the market, saying planting “aerospace seeds” can increase production and increase revenue. Recently, the relevant agricultural experts remind that to scientifically treat space breeding, do not deify and superstition, let alone paste the “space” label. Introduction of agricultural experts, aerospace breeding is the seeds of plants in the return spacecraft, the use of space magnetic field, weight loss, radiation and other environmental factors, mutations in the seed gene, after returning to the ground, through breeding experts carefully cultivate the excellent yield New varieties, thus significantly improve crop yield and quality. Due to the complexity of the space environment and the individual adaptation of the seed to the environment, not every seed that enters space
