In the agricultural sci-tech sphere,
China has constantly narrowed
its gap with the advanced countries. The contribution rate of scientific and
technological progress to China's agriculture has increased from 20 percent in 1949 to 42 percent.
The agricultural sci-tech departments have made much progress in bio-technology,
new and high technology and basic research, and the cultivation of plant cells
and tissues, anther culture, haploid breeding and the research on its
application have reached the world's advanced level. Bilinear hybrid rice,
hybrid corn breeding and multi-crop planting technologies featuring intensive
cultivation have reached or approached the world's advanced level. In addition,
an important breakthrough has been made in the research of making use of the
advantages of hybrid beans.
In February 2001, the Chinese scientist Yuan
Longping was given the state highest sci-tech award. His research achievements
in hybrid rice have rewritten the Chinese history of the cultivation of rice in
the second half of the 20th century, and made outstanding contributions to
solving the issue of mankind's grain ration. Since 1949, China's agricultural scientists have improved
more than 40 kinds of crops, and developed nearly 5,000 high-yield and
good-quality new varieties with strong resistance. Thus the major farm crops
have been renovated four to five times, each renovation increasing yields by 10
to 30 percent. The per-ha yield of grain crops has increased from 1.16 tons in
1950 to 4.82 tons, an increase of more than four times.
The relevant state departments have
organized the implementation of the sci-tech programs directly geared to the
rural economic development, such as the Spark Program, the Promotion Plan of
Important Achievements, the Bumper Harvest Plan, and the Prairie Fire Program,
to send advanced sci-tech achievements to the countryside and to farmers' homes,
thus playing an important role in improving farmers' sci-tech quality.
Meanwhile, agricultural departments have
imported more than 100,000 farm crops and nursery stocks from different
countries and regions of the world, and cultivated new varieties of rice, corn
and wheat. Plastic film mulching, dry breeding of rice seedlings and their
sparse planting, new farm tools and farm pesticides and other advanced
technologies have been extensively applied in production.
