The glass greenhouse has strong environmental control capabilities and sufficient factory production conditions, making it a high-end type among many facilities. However, the cost of glass greenhouses is high. In the field of my country's facility agriculture where plastic film greenhouses, solar greenhouses, and greenhouses are the mainstream, whether glass greenhouses can be profitable has always been debated and doubted whether it is in academia or business circles. The Wallenda effect based on glass greenhouses was born from this, which made us focus too much on whether this type of greenhouse is suitable for our country, but not enough on how to innovate, select, and utilize.

From the perspective of modern factory agriculture, the greenhouse provides space and environment for the factory production of facility horticultural products, and is a factory building for the production of agricultural products. If you change your position, if you invest in the production of other consumer goods, almost no one will ask what kind of plant can be built to make a profit? Modern facility horticulture production has the conditions to realize good precision control and digital management, to realize the assembly line operation of subdivided links under strict process, and to produce goods as planned. From the perspective of production process control, there is no essential difference from industrial production. . Of course, outdoor climate conditions and production control of different varieties cannot be replicated. This is the difference between greenhouse production and industrial production, which is aggravated by plant living objects. However, this difference can be resolved through the production test before reaching production and the establishment of a production technology system based on its own characteristics. Therefore, it can be said that whether the glass greenhouse can be profitable is actually a false proposition and does not need to be discussed. What should be discussed is how to use the glass greenhouse and what to do in the glass greenhouse to make a profit.

First look at the current investment practice of glass greenhouses in my country. As one of the plant types for facility gardening, glass greenhouses have existed all over the world for many years, especially in the Western capitalist world where profits are the goal. It can still exist for a long time. Its commercial feasibility is beyond doubt. The shrewdness of capital is not weaker than the reasoning of scholars. The author organized a team to conduct a survey on the operation of newly built glass greenhouses in China in recent years. The survey found that in the past five years, more than 800 hectares of newly built glass greenhouses have been built. There are 214 hectares of greenhouses that have been put into operation and have a yield rate of more than 80% in the past five years. In ten provinces in my country, the products cover dozens of subdivided horticultural products such as vegetables and flowers. Basically, 33% of the profits have been achieved. The rest have not yet entered a profitable state, or are still losing money, or have achieved a level of production and operation. What is more noteworthy is that after a period of practice, these investors and operators have become more and more confident in profitability, and they have clear profit time expectations. This is the result of our country's current practice.

Secondly, discuss the minimum requirements for return on investment in glass greenhouses. In terms of cost, including environmental control equipment and planting systems, glass greenhouses often require more than 1,500 yuan/square meter, and glass greenhouses with strong environmental control capabilities and high automation of the planting system can cost as much as 2500-3200 yuan/square meter. Compared with the plastic film multi-span greenhouse doubled or even several times. However, due to its good airtightness and stable material life cycle, glass greenhouses have more precise environmental regulation capabilities and stronger annual production capacity. Glass greenhouses need to be treated as workshops to configure production equipment and organize production activities to achieve efficient and intensive Production line. Therefore, in the case of the same scale, the requirements for production efficiency and unit output value are naturally higher than those of my country's traditional greenhouse facilities in order to meet the basic business logic of return on investment. The following table lists the glass greenhouses with different investment levels, calculated based on 20 years of greenhouse depreciation and 10 years of equipment depreciation, and the financial cost is calculated based on the benchmark interest rate. The calculation of the unit output value that should meet the dynamic investment payback period of 15 to 18 years Reference model.

According to the minimum gross profit and output value requirements in the table, a combination of categories, technologies, products, and channels that can achieve the target must be selected to ensure the realization of profits. It should be noted that the output value and gross profit data listed in the table can only guarantee the basic internal rate of return (about 7-8%), and the dynamic investment payback period is close to 18 years. In other words, the investment is recovered within the depreciation period of the greenhouse, and the income obtained from the use of the greenhouse after the depreciation period is the cash return for investment behavior. Therefore, it can be considered that, as an agricultural project with a low expectation of return, achieving the above goal is profitable, but compared with other commercial projects with the same investment amount, the profitability is low. If it is necessary to increase profitability and shorten the payback period, further steps are needed. Improve profitability.

Third, are the above requirements realistic? Can the target of output value per unit area be achieved in actual production? Assuming the production of clustered tomatoes, the unit yield is 20Kg/square meter, and the shipping price at the origin must reach 25 yuan/Kg or more. Based on the survey of the operation of planting companies, the author found that 15% of the companies have achieved this goal. The author's survey of mid-to-high-end supermarkets such as Beijing BHG also found that the retail price is higher than 45 yuan/Kg, and according to the introduction of the supermarkets, the sales rate and turnover rate are both high. It can be considered that this goal is achievable under the current consumer demand, but there are certain difficulties. It is necessary to break through the traditional agricultural product sales thinking and achieve a high level in the three aspects of management, marketing, and technology. .
