摘要：Rice is grown
in more than
100 countries.
According to
the Food and
Agriculture
Organization
of the United
Nations (FAO),
the global rice
area harvested
in 2005 was
153 million
hectares. The amount of land used for
rice is less, in the order of 127 million
hectares, because in some fields
farmers plant two, or even three,
rice crops each year. One hectare
of double-cropped land therefore
provides 2 hectares of rice area each
year (areas referred to hereafter
are harvested areas, as opposed to
actual land areas). On this land,
farmers produce 628,000,000,000
kilograms of rough (unmilled) rice.
This averages
out to about 95
kilograms for each
person on Earth.
