RiceAs one of the world's most important crops, it plays a pivotal role in ensuring global food** and economic development. However, despite the fact that China is one to cultivateRiceMainAgricultureGreat powers, butRiceHowever, production has been surpassed by the United States in recent years. This result may come as a surprise, after all, China actsRiceThe birthplace of plantingRiceIt has a history of thousands of years.
First, let's take a lookRiceThe importance of the matter. RiceAs a basic food for humanity, it plays a key role in global food production and the economy. However, China once faced severe hunger and long-term dependence on importsRice。Through research and development, China has successfully cultivated the most advanced in the worldRiceVarieties –Hybrid rice。This kindRiceThe varieties have higher productivity and drought tolerance, which has helped China significantly increase grain production and solve the problem of food shortage. ChineseHybrid riceThe R&D work benefited from the painstaking research led by Yuan Longping for more than ten years, and successfully cultivated the world's first oneHybrid rice。ChinaHybrid riceThe success has not only improvedRiceThe yield per mu has also been promotedAgricultureThe innovation of production methods for China and even the worldAgricultureDevelopments have had a profound impact.
ChinaHybrid riceThe success has attracted wide attention from the international community. In the face of a food crisis,United States**It also learned from China's successful experience and invited Yuan Longping to lead a team of experts to visit the United States for promotionHybrid riceTechnology. ChinaRiceThe new varieties have been widely introduced and cultivated in the United States, increasing yields and providing more income opportunities for local farms in the United States and around the worldAgricultureThe development has had a profound impact.
The study found that despite the fact that the United States isAgricultureStrong country, but inRiceThe level of technology in cultivation has not reached the level of China. China has been in for a long timeRiceThe field has invested a lot of resources to promote scientific and technological innovation, and has accumulated rich practical experience. In addition, although China's land is fertile, it cannot be cultivated on a large scale like in the United States due to factors such as a lack of sufficient water resources and complex climate changeRice。Southern ChinaRiceThe planting area is large, but other areas cannot be planted on a large scale due to natural conditions.
In addition, China's land resources are facing serious problemsSoil contaminationIssue. The excessive use of fertilizers and pesticides over the past few decades has led to the accumulation of pollutants in the soil, which has had a serious impactRicegrowth and yield. In order to solve this problem, China** has implemented a series of policies to protect the soil and the environment, such as reducing the use of chemical fertilizers and pesticides, and promoting organic farming. However, it will take time for these measures to bear fruit, and there is still some impact.
Finally,RiceThe way of cultivation may also affect ChinaRiceA factor in yield. Traditionally, China has adopted paddy field cultivation, which is more water-intensive. And in the United States, the rice fieldsdrainage systemmaking it more suitable for cultivation in arid regions. China** is also currently promoting improved planting practices, such as:Water-saving irrigationwithStraw returningetc., to reduce dependence on water resources.
To sum up, although China isRicebut in recent years it has been surpassed by the United States for many and complex reasons. These include the United States learning from China's successful experience, the difference in the level of science and technology, land resources andSoil contaminationand other factors, as well as differences in planting methods, etc. China** has been aware of these problems and is working to solve them in order to improveRiceYield. In the future, China will continue to be committed toRiceResearch and development for the worldAgriculturedevelopment to make a greater contribution.
