答案
自己再提炼一下吧..:)
IT is said every scientist cherishes a childhood dream indicating his or her future success,but for Yuan Longping,dubbed as "father of hybrid rice," the dream is that he cultivates rice as plump as peanuts,and farmers can relax in the cool shadow of big rice plants.
Yuan came up with the idea of hybridizing rice for the first time in the world in 1960s.Since then,50 per cent of China's total rice cultivation fields have grown such rice,which added some 300 billion kilograms to the country's grain output.
Furrows grown on his sunburnt face,a slim figure and coiled-up trousers legs would confuse foreign reporters who came to interview the most famous scientist in China,who would rather be called "a farmer".
However,Yuan said his research requires the lifestyle of a farmer,or rather a migrating farmer,as he has conducted extensive research related to the cultivation of new strains of hybrid rice "Super Hybrid Rice" in some 10 provinces.
In the year 1999,more than 300 billion kilograms of grain were increased from about 240 million hectares of hybrid rice,which signified the success of his research.And this made Yuan firmly believe that China can surely feed her 1.2 billion population with her limited cultivated land.
The "Super Rice" yields are 30 per cent higher than those of common rice.The record yield of 17,055 kilograms per hectare was registered in Yongsheng County in Yunnan in 1999.
But even after that achievement Yuan won't take a break.He has a dream,more realistic than that of his young age,that popularizing new strains of grain with higher yields around the world,can eliminate starvation on earth.
The UN Food and Agriculture Organization (FAO) has vowed to get involved in the work of spreading the coverage of Yuan's high-yield hybrid rice,which it considers the best way to increase the world's grain output.
The FAO's 1991 statistics show that 20 per cent of the world's rice output was yielded from 10 per cent of the world's rice fields,which grow hybrid rice.
"If the new strain was sown in the rest of the rice acreage,the present grain output around the world can be more than doubled.This can be a solution to the grain shortage," said the unselfish scientist.
