12-year -old American boy Maxwell Daley just grew a pumpkin(南瓜) that weighs 582. 5 pounds (1 pound is about 0.45 kg). He won first place in the seventh annual Largest Pumpkin Contest at the Kentucky State Fair. And he received the $500 (about 3, 334 yuan) top prize.

    Maxwell is a seventh grader at Grayson County Middle School. At the age of 8, he became interested in growing huge pumpkins after seeing them at the state fair.

    Maxwell is a boy of few words. But he shared his secret of growing a big pumpkin" We put lots of special fertilizers(肥料) on it. We put it in the shade(阴凉处) and put a canopy(遮篷) over it. Lots of weeds(杂草) need to be pulled," he told local media Franklin Favorite.

    His father Joe Daley also added that it started by picking the right seed this year, Daley paid $ 40 for his pumpkin seed and worked hard every day to grow it. He also needed to keep the pests(害虫) out. "It turned into a pretty big job. He did all the work," Joe said.

    This winning giant pumpkin was the only one he grew this year. According to the rule, Maxwell has to take part in the Largest Pumpkin Contest for years to come.
