Space vegetables not only have the advantages of high yield, good quality and disease resistance, but also space breeding is a new way of breeding, which has advantages that other breeding methods do not have.
In space flight, all living beings on board will be affected by many factors, such as flight dynamics, environmental factors in the flight capsule, space radiation factors, and factors from within the organism. These factors generally work together on biological species. Generally speaking, in the study of plant space biology, the space-specific microgravity environment and space radiation factors are the focus of research.
In some studies, it has also been confirmed that the strong impact under microgravity conditions or during satellite launch will break the cell wall of plants, resulting in increased water absorption and electrical conductivity of seeds, which can promote plant growth and development.

It is mainly the genetic mutation of seeds under the conditions of high vacuum, microgravity, and cosmic rays, which improves the yield and quality.
The number of seeds that get into space is large, and the mutation is random, and only a small part changes in the expected direction, so there is still a selection process back on the ground.

Space vegetables refer to the ordinary vegetable seeds carried on the space satellite, after the Taisan Kai space weightlessness, lack of oxygen and other special environmental changes, the internal structure of the radical change, washed back to the ground, by the agricultural experts for many years to cultivate. The nutritional content of space vegetables is higher than that of ordinary vegetables, and the content of trace elements beneficial to the human body is increased by iron, zinc is increased, copper is increased, phosphorus is increased, manganese is increased, and carotene is increased.

In the absence of gravity and bacteria, it can make organisms resistant to disease and drought.

So, why did the space flight take these plant seeds with it? Can they also describe a wonderful journey to space?
Plant seeds don't speak, but we have a way to understand their experiences during space travel. Scientists let these seeds take root and sprout, and when compared to similar plants that have not been in space, they often find some interesting differences. For example, eggplant seeds that have been aboard the Shenzhou-1 unmanned spacecraft produce fruits that are larger than a basketball and smaller than an egg.
Scientists select and breed excellent varieties from the sifting (shāi) and promote them, so as to promote the development of agriculture, forestry and animal husbandry. After years of hard work, experts have cultivated new varieties such as "space rice", "space tomato", "space cucumber" and "space pepper". They generally have the advantages of high yield, good quality and strong vitality.
Where do these advantages come from? From space.
In the vastness of space, due to the radiation (fú) radiation of cosmic rays, due to the special environment of microgravity and high vacuum, the genetic material inside some plant seeds has undergone subtle changes. Some plant seed offspring change in the desired direction, e.g., fruit becomes larger and disease resistance increases, while others change the opposite. Scientists select and breed the seeds of plants that travel through space, continuously select and breed excellent mutant plants, eliminate those bad mutant plants, and cultivate excellent mutant plants for more than four generations to stabilize their traits and finally cultivate them into new space varieties.
Now, space vegetables have entered thousands of households and become a delicacy (yáo) on our tables. For example, space cucumbers have greatly increased levels of iron and vitamin C; Space hoists can grow up to a meter long; Space peppers are not only big and delicious, but also produce beautiful yellow bell peppers and red bell peppers. In addition, because space vegetables are highly resistant to diseases, pesticides are rarely used in the growth process.
They are wholesome green vegetables.
In addition to food, there are many uses for these special passengers returning from space! Scientists have found that some of the vegetable gourds cultivated with space seeds have become bitter. This is because the content of bitter melon in it is increased.
Therefore, some experts plan to extract bitter melon from the space vegetable gourd to develop a good medicine for diabetes (niào) disease. There are also scientists who are working to cultivate more beautiful and novel space flowers to beautify our lives. In addition, people also hope to obtain new grass species and tree species that are drought-tolerant and salinity-tolerant (jiǎn) through space breeding, which can be used to better green the motherland and maintain water and soil.

Space vegetables are filtered through space, which has high yield and high temperature resistance, is more conducive to growth than ordinary vegetables, has strong drought resistance and virus invasion prevention ability, and has a variety of advantages. Space vegetables do not need to be sprayed with pesticides, which is more protective for people's health! It has been supported by the China Academy of Space Technology and the Institute of Genetics of the Chinese Academy of Sciences, due to its particularity, it is more suitable for transportation and storage, and will not be put for a period of time to deteriorate, space vegetables have special antiviral ability and higher yield than ordinary vegetables, in the planting process can not only apply less fertilizer, do not spray pesticides to maintain our health, but also improve the economic benefits of space vegetables.
Space vegetable seeds are carried on space satellites, after special environmental changes such as weightlessness and hypoxia in space, the internal structure undergoes drastic changes, and after returning to the ground, it has been cultivated by agricultural experts for many years.

It's nutritious, it's good for your health, and it can also cure diseases.

Space vegetables are vegetables that are grown through space radiation breeding. Many, like many green peppers and melons, are bred in this way.

Hello, glad to answer for you.
There are a lot of du's in space vegetables
Such as: too empty bell pepper space purple sweet potato carrot dao space tomato for you will be the advantages of a simple subordinate.
1. Nutrition: The vitamin content of space vegetables is more than 2 times higher than that of ordinary vegetables, and the content of trace elements beneficial to the human body is increased by iron, zinc is increased, copper is increased, phosphorus is increased, manganese is improved, and carotene is increased. The soluble sugar content of space tomatoes is 25% higher than that of ordinary tomatoes.
The content of lysine, copper, manganese, potassium and zinc in space purple sweet potato is 3-8 times higher than that of ordinary sweet potato, especially the content of iodine and selenium, which is more than 20 times higher than that of other sweet potatoes, accounting for the first place in food.
2. Taste: It is more delicious and delicious than ordinary vegetables, such as space bell peppers can be eaten raw directly, with a slightly sweet taste, crisp and refreshing. Space purple sweet potato raw food taste sweet, water sufficient, cooked food set fragrant, soft, sweet in one, color, fragrant, taste are good, is the city residents, hotels, restaurants of the top health food.
Hope it helps.

It can cure the disease and eat it is good for us. Space vegetables are more than twice as nutritious as ordinary vegetables and are beneficial to the human body. After eating space vegetables, our bodies will be better. Doesn't get sick easily.
