As China's main food crop, rice plays an important role in the world, however, although China's total grain output has reached a record high, rice production has been surpassed by the United States, which has aroused people's thinking. What is the reason why the United States has achieved higher rice yields with the same seeds?Below we will analyze from several aspects.
As an important food crop, rice plays an extremely important role in world food production and economy. China's hybrid rice has dramatically increased its grain production in the past decade and has made remarkable achievements. This successful case not only promotes China's own food production and economic development, but also provides an effective way for other countries to solve the problem of food shortage. However, the U.S. is relatively less technologically advanced in rice cultivation than China, which has led to higher yields of the same seeds in the U.S.
In contrast, the United States has a wide range of arable land and flat land conditions, which are very conducive to large-scale mechanized farming. Its agricultural technology is also very advanced, especially the application of precision irrigation technology and drone plant protection system, which has greatly improved agricultural production efficiency. In addition, the United States is also constantly introducing new types of seeds, such as "super rice" and "hybrid rice", which not only have higher yields, but also have superior quality.
In contrast, although China has a large total area of cultivated land, most of it is mountainous slopes, hills and other terrains, which are not suitable for large-scale mechanized operations. In addition, due to limited land resources and diverse consumer needs, it is difficult to expand the scale of rice cultivation in China. Coupled with water scarcity in China, especially during the dry season, irrigation has become a bottleneck limiting rice production. The soil in China's main rice areas is mainly sandy loam and red and yellow soil, and the nutrients are relatively poor, which also limits the yield of rice.
However, Chinese scientists have been working hard to develop new rice varieties with more potential, and through advanced breeding techniques such as molecular marker-assisted selection, as well as comprehensive screening of hybrid advantages, resistance and quality, the average yield per mu of rice in China has been continuously improved, providing a strong guarantee for solving the problem of food security. China's Ministry of Agriculture and Rural Affairs has also launched the construction of high-standard farmland and high-efficiency rice production functional areas, and vigorously promoted mechanized operations, high-yield cultivation technologies and supporting demonstrations of fine varieties, which have directly led to the increase of farmers' incomes. In general, the combination of scientific and technological progress and technological experience has enabled the rapid development of China's rice industry.
Looking forward to the future, we are confident that we will make breakthroughs in the fields of science and technology and management to improve the efficiency of rice production in China. However, in the face of global environmental change, population growth and rising food demand, we need to continue to innovate and challenge ourselves to meet the challenges of the future and ensure the sustainability and stability of rice production. This is a goal that requires the joint efforts of the whole society, and it is also a future full of hope and challenges.
