A well-known economist, Professor Zhang, has sparked widespread controversy in his views on social platforms. In the video, Professor Zhang said that if farmers contract 30 acres of land to grow celery, they can earn 2 million yuan a year. Would you like to come? Or if I plant 30 acres of vegetables, you can harvest them.
Many netizens said: These experts who sit in the office blowing the air conditioner and drink tea, the income of the common people is calculated by their hands? Eaten with your mouth? Then China's farmers are multimillionaires. Although Professor Zhang himself is an economist, he has no direct experience in agricultural production.
Such statements should be based on theoretical inferences, not conclusions drawn from field investigations. This will inevitably lead to some differences. Some celery farmers say they don't look at all the costs: 30 acres of celery land planted for two seasons a year may have an output value of 2 million yuan, but many practical factors must be considered.
Soil, topographic, and water conditions. High yields are possible only with good natural conditions. Otherwise, it is difficult to guarantee the output.
Fertilizer and water conservancy inputs. High-standard cultivation requires a lot of fertilizer and water input, and this expenditure should not be underestimated.
Labor costs. The management and harvesting of 30 acres of land require a large number of manpower, and the labor cost is also very high.
Pest and disease control. Aphids or other pests and diseases may be exposed to different seasons, and the need for precise control is also an important expense.
Market prices fluctuate. The price of celery changes every year, and it is difficult to guarantee that the final selling price will reach the estimated level.
Other hidden costs. For example, it is difficult to accurately predict the expenditure of seed purchase and technical services.
There is also the rent fee for the farmland. I have never heard of a family with 30 acres of land, and if there is such a fee, it can be waived. However, in reality, many farmers do not. If you want to build a greenhouse, it is another expense.
It is necessary to control various costs and risks, and the net income of 1,000 yuan per mu is already a very effective industrial model. To reach the level that Professor Zhang said, 30 acres of land is almost impossible. Therefore, for an ordinary farmer, it is still very difficult to earn 2 million yuan a year from 30 acres of celery land.
Although with the upgrading of agricultural industrialization, under large-scale operation and professional management, the yield per mu can be significantly improved, which is also the general direction of agricultural development. The possibility pointed out by Professor Zhang is valid in theory, but in practice, many conditions need to be fully met. Rather than focusing too much on individual figures, we need to understand the issue in the big picture and in the long term.
In short, when discussing other people's areas of expertise, we need to maintain a cautious and objective attitude, fully understand the context, and not be based on subjective assumptions. It is also hoped that relevant experts will consider more practical factors before publishing their arguments, so as not to be misleading. Only through in-depth study and communication can we examine the problem from various aspects and draw more realistic and reasonable conclusions.
conclusion
The development of modern agriculture is no longer just relying on traditional decentralized cultivation to achieve efficient profits. Only through large-scale, standardized and professional ways can we truly reduce various costs and improve yield efficiency. At the same time, we also understand what professionals need to be aware of when expressing their opinions.
Before the theoretical argument is promoted, the constraints at the practical level should be fully considered to avoid misleading. As public figures, we should be more prudent and responsible. We hope that all walks of life should conduct more on-site visits and exchanges in order to have a comprehensive and in-depth understanding of the problem.
Dialogue and coordination between voices from different positions can help solve problems in a peaceful and tracing manner. We believe that this is the only way to promote sustainable agricultural development and improve the quality and efficiency of public discourse. That is the right way to start the discussion.
