A successful experiment (实验) in the deserts of Dubai (迪拜) may deal with hunger around the world. A team of Chinese scientists has tried to develop a kind of rice that grows in salt water. Not only that, it produces far more rice than you can imagine.

Back in January, 2018, the researchers were invited to plant some of the saltwater rice in different areas of the desert. Usual water is too expensive to waste on rice in those desert areas. After five months of growth, they produce up to 7.8 tons of rice a hectare (公顷). At the same time, the world average (平均数) stands at 3.3 tons a hectare.

The researchers from China are continuing the experiment by setting up a 100-hectare salt-water rice farm in 2019. It will show the costs of production and different farming skills. They hope to plant saltwater rice on more farms in 2020.

Their dream is to cover up to 10% of the country with the saltwater rice fields—and if the skills are successful in Dubai’s bad farming weather, then the farms could “feed the whole Arab world and they help to ensure (确保) food security (安全)”.

Yuan Longping is the “father of hybrid rice” and leader of the research group. He says that there are over l million square kilometers of land in China that is not used because there is too much salt in the soil. By planting saltwater rice on just one-tenth of this land, we hope it will feed over 200 million more people.

Carrots are grown all over the world. They are easy to plant and easy to harvest. They have a good taste.

When people think about carrots, they usually think they are a kind of long, thin, orange colored vegetable. In fact, carrots are in many different sizes and shapes. And not all carrots are orange.

Carrots should be grown in a field that does not have water for a long time. The earth also should not be too hard. To prepare your carrot garden, dig up the earth and turn it over(翻土).?

Weather, soil condition(土壤状况),and time affect(影响)the taste of carrots. Warm days and cool nights are the best time to grow great delicious carrots.

The best way to decide if a carrot is ready to be harvested is by its color. Usually, the brighter the color is, the better the taste is.

Most people do not know that carrots can be grown during the winter months. If the winter is not cold enough to freeze the ground, you can grow carrots the same way as you do during the summer months.

Carrots are prepared and eaten in many different ways. They are cut into thin pieces and cooked with other vegetables or meat. Or, they are washed, and eaten just as they come out of the ground.
