A new AI system can be used to make predictions(预测) on the crop yields(产量) up to six months before harvest. The tool counts flowers on fruit trees, which can help farmers improve crop yields and make better use of water and labor, and to plan harvests.
The system, developed by researchers at the National Robotarium in Edinburgh, can count flowers on fruit trees from photos taken by a smartphone. It works by knowing features, such as the edges and shapes of flowers. In Spain, studies on peach trees showed the system to be 90% correct in flower counts, which is much better than the 30% to 50% mistakes made by humans, according to researchers.
"In countries all across the world, farmers often depend on traditional methods to predict their yields, which can lead to big mistakes, " said Fernando Auat Cheein, a professor at the National Robotarium. "The flower-counting AI makes it possible to help farmers make wise decisions about crop management. "
"By paying more attention to the areas of the farm that are expected to produce the most fruit, farmers can make the most of resources(资源), reduce their environmental effect, and improve the harvest, " said Mr Cheein. "Our AI tool can be used with traditional farming practices, making it easier for growers to get help without completely changing their present methods. " The researchers will next compare the AI's predictions with the actual peach harvest in the following months. If these turn out to be effective (有效的), they believe the method could be used for crops such as apples, pears, and cherries, helping fruit growers in Britain, Europe, and other areas.
Is your school strict?
| Alice： Well， yes and no. At break time we can decide（决定）where to go. We can stay in the classroom or go outside—I often go to the playground with Mike, but we can't go out to the shops and of course we can't go home! |
| Karl: Yes, the teachers are very strict! We can't talk in class and we can't ask questions. We can listen to the teacher and copy（抄写）from the board. That＇s all! |
| Jane： Not really， no. We can use computers in class to look forinformation（资料），but we can＇t go on social networking sites（社交网站），of course！We can work in groups in class too. I like that. |
Mr. and Mrs. George and Olivia Ransom bought an old house, and were spending time fixing it up. The walls needed painting and the wooden floorboards(地板) needed replacing.
One day, they pulled (拉) up some old floorboards and were surprised to see a case under the floor. They pulled it out, dusted it off and opened it. It was full of old newspapers from the year1977. George and Olivia were interested to read the news stories at that time. But as they took the newspapers out, they noticed a black box at the bottom of the case. It was locked.
Then Olivia remembered that there were some old things in the kitchen. There was a cup with old keys in it. She ran to get the cup, took out the keys and tried them in the lock. One of them opened it!
The box was full of jewellery (珠宝). There were necklaces and rings of silver and gold. Olivia and George were amazed. Who put the jewellery there, and why? Who did it belong to?
George remembered a story in the old newspapers. He quickly found it again and they read it together.
Police Unable to Solve Jewel Mystery 2 May, 1977— It has been three weeks since thieves robbed Jensen'sjewellery Store, but the police are no closer to solving the mystery of what happened to the jewellery. The jeweller, Stanley Jensen, said he was disappointed(感到失望的) that the police still had no answers... |
"That name— Jensen, said George. "It's familiar to me— why?"
"It's the old lady who sold the house to us!" replied Olivia. "Her name was Mrs Jensen. She told us her husband died in 1978 and he was a jeweller."
"That's strange," said George. "I wonder, was there really a jewellery theft? Or did Stanley Jensen hide the jewellery under his own house? But why...?"
