With the rapid development of modern agricultural technology in recent years, intelligent modern glass greenhouses have been constructed all over the world. However, the industry also has some problems. Some glass smart greenhouses that cost millions or even tens of millions have not been fully utilized. It looks very high-end from the outside, but when I went inside, I found weeds overgrown. In contrast, all kinds of high-tech can be seen everywhere in the Dutch greenhouses, and the crops are thriving. The same greenhouse has a completely different scene. What is wrong?

First of all, the Netherlands has an oceanic climate. The temperature is warm in winter and cool in summer, which is more suitable for the growth of crops. However, the lack of light has been improved through improvement, so an all-glass greenhouse has appeared. Through the heating and cooling system, the temperature in the shed can be controlled all year round in an environment suitable for the growth of crops. Vegetables can be grown throughout the year. The cost of heating in the Netherlands in winter is relatively low. Natural gas heating is used, but the outdoor temperature in northern my country is low in winter. The cost of heating natural gas or coal is very high. The temperature in the shed in summer is very high. Although there is a ventilation cooling system, it is only an auxiliary system. For some crops that require relatively high temperature, it is also not suitable for summer planting. Therefore, the planting is basically in the spring and autumn season. In the spring and autumn season, the price of vegetables is not high, but the glass greenhouse is expensive, so it is basically a loss if it is not carefully managed.

Is the glass greenhouse not suitable for promotion? Of course not. The construction of modern agricultural glass greenhouses in some places is to obtain subsidies. Many projects involve people who do not understand agriculture to engage in agriculture in order to subsidize them. This vicious circle has occurred. Large-scale agricultural parks have specialized technical experts. The use of Dutch technology for refined management in operation and management is actually no worse than that of Dutch greenhouses, because the Netherlands has been developing agriculture since the 1950s, but most countries have people who really understand agriculture. Not much. With the development of science and technology, it is necessary to slowly explore the path of agricultural development. As labor costs are getting higher and higher, smart greenhouses are becoming more and more popular, and there is no need to manage too many people to save labor costs. It is planted all year round and the yield is high. Any emerging mistakes have a development process. I believe that in the next few years, the development of modern agriculture will surely be in line with developed agricultural countries, and the development of smart glass greenhouses will definitely get better and better.
