Since humans sent the first satellite(卫星) to space in the 1950s,scientists have been studying an important topic:how to grow plants in space if humans live there one day.A recent experiment at the Tiangong space station makes a big step forward.
Chinese astronauts have successfully grown rice seedlings(幼苗) during the Shenzhou XIV mission.The researcher said,"The rice seedlings are growing very well."Since the rice experiment began on July 29,the seedlings of the tall shoot rice variety(高杆水稻品种) have reached a height of 30 centimeters.The seedlings of the dwarf rice variety(矮杆水稻品种) have grown to 5 centimeters,China Daily reported on August 30,2022.
While there have been other rice experiments in space,this one is the first of its kind to produce the complete life cycle of a plant—it begins with a seed and ends with a grown plant producing new seeds.
Such food﹣growing experiments are not for astronauts.They can solve food problems on Earth.By sending seeds to space,we can create mutated(突变的) seeds that can produce higher yields(产量)on Earth.
For more than 30 years,China has developed over 260 new types of seeds in space.They are planted on Earth every year.
According to Yao Tong,an engineer from Hainan Aerospace Engineering Breeding Research Center,30%of strawberries sold in Beijing are "space strawberries",which are as big as eggs.The center has also produced "space tomatoes"with yields increased by 30%,and "space bananas"with a growth cycle shortened from 13 months to 9 months.
