太空,希望的田野人类正面临着来自粮食短缺的挑战。我国人口每年以1400万的速度递增,可耕土地锐减,现有农业增产潜力不大,因此“菜篮子”、“米袋子”一直是各级政府官员所始终关心的一个问题。多年来,我国一代又一代农业科学家,面对着黄土地、黑土地苦苦探索、追寻优良品种,终无大的突破。随着太空技术的发展,他们把视线投向了茫茫太空。自1987年至今,我国已先后8次利返回式卫星进行了51种植物300多个品种的太空培养试验。而后,它 Space, the human field of hope is facing challenges from food shortages. As China’s population increases at a rate of 14 million a year, and arable land is drastically reduced, the existing agricultural production potential has little potential. Therefore, “vegetable baskets” and “rice bags” have always been issues that government officials at all levels have always cared about. Over the years, after one generation of agricultural scientists in China, in the face of hard exploration and pursuit of fine varieties in yellow land and black land, there has been no major breakthrough. With the development of space technology, they have turned their sights into space. Since 1987, China has carried out space culture experiments on more than 300 varieties of 51 species of plants using eight return satellites. Then it
