The most familiar vegetable in space should be space pepper. The varieties of green peppers that have experienced space tourism are not only very good, but also much larger than ordinary green peppers. Is bringing vegetable seeds to the space fund just to make vegetables bigger and tastier? Actually, it is not. In fact, sending seeds into space is to use the principle of weightlessness in space to carry out vacuum and strong radiation on seeds and make them mutate. Moreover, X-rays and Y-rays in space can also change the genetic material of vegetable seeds, and then choose better vegetable varieties through human intervention.
According to incomplete statistics, the extension area of space cultivated crops in China has now exceeded 2.4 million square kilometers, and the annual grain output has increased by more than 654.38+0.3 billion kilograms, with considerable economic benefits. Moreover, the quality and quantity of new varieties cultivated through space breeding are very good, such as Xinjiang cotton, which was very popular some time ago. Actually, it belongs to the product of space breeding. Moreover, the germination rate, disease resistance, insect resistance and nutrient absorption capacity of seeds that have survived in space for a period of time will be greatly enhanced, and the appearance and characteristics of these plants will also change.
However, the changes of these seeds in space are not very regular, so not all seeds can complete normal variation in space, and some seeds become unfit for eating after space travel. Nowadays, space vegetables are still relatively common. These space dishes are sold in large markets in Shandong, Jiangsu and Hebei, and the price of space dishes is slightly higher than that of ordinary vegetables. But compared with ordinary vegetables, space vegetables are superior in taste, nutrition and color.
