The benefits of a glasshouse horticulture area largely depend on climatic conditions. Temperature, humidity, and sunshine are the determinants of the output per square meter of glasshouses. It is no coincidence that most glass greenhouses are concentrated in coastal areas. The climate in the coastal areas is usually mild, cool in winter and cool in summer. Sunshine is strongest in the coastal areas. In the inland areas 200 kilometers away from the sea, the sunshine will be reduced by several percentage points. More light means better growth and higher quality. If stable weather conditions can be maintained, crop growth, development and maturation can be controlled. Artificial artificial sunlight can also be used to grow vegetable seedlings.
Dutch glasshouse vegetable growers benefit from the existence of suppliers and their knowledge. They have comparable computer-based control systems, water and fertilizer supplies, substrates, climate (control), lighting, crop breeding, seed production, propagation, (biocontrol) crop protection, mechanization, internal and external transport, and grading and packaging of glass greenhouses. Knowledge and experience can be said to be expert hands. For the same reason, supply companies also benefit from the presence of Dutch glass greenhouse vegetable growers and their knowledge. The knowledge that growers have is also exported. The Dutch glass greenhouse construction company owns 80% of the world market share.
The computer has played an important role in the Dutch glass greenhouse. The computer can not only control the water supply, fertilizer supply, climate, temperature, ventilation, humidity, and carbon dioxide content in the air, but also control the solar radiation rate in the greenhouse. When the sun is too strong, the sun shade will automatically drop. Optical sensing devices replace the human eye in automated harvesting, shipping, grading, and packaging systems.
Artificially improving the plant's environment has now reached fairly advanced levels. The original soil type in the greenhouse area is now almost irrelevant for many crops, as nearly half of the vegetable farms (43%) have used soil as the substrate. To cultivate crops, approximately two-thirds (64%) of the glass greenhouse vegetable is grown from a substrate. All the fruits and vegetables, such as tomatoes, cucumbers and sweet peppers, are planted on the substrate.
The reason why planting vegetables in glass greenhouses has become a reality is the result of reform and innovation. Innovation and innovation are still a major feature of Dutch glass greenhouse vegetable gardening today. In converting new concepts into practical solutions and in improving existing technologies and developing new technologies, scientific research stations, pilot farms, universities, technical schools, consulting agencies, plant breeding companies, seed and seedling producers, equipment manufacturing companies Both growers and flower growers play an important role.
The modern technology of glass greenhouse vegetable gardening has led to a continuous increase in production. In 1975, only 30 kg of vegetables were produced per square meter, and now it has reached 60 kg.
In addition, the variety of vegetables grown in the Netherlands is constantly expanding, and there is more room for selection of the color, aroma, taste and type of these varieties.
Tomato is one of the many current paradigms for the development and expansion of varieties. Consumers no longer prefer traditional round tomatoes. In order to satisfy consumers' wishes, tomato growing owners also offer various types of hard-tomatoes, cherry tomatoes, and creeping tomatoes, in addition to round tomatoes. Its own characteristics, colors and flavors.
Recently, with the introduction of Baby Bell Peppers, sweet pepper varieties have added a new member. Baby bell pepper tip, only a few centimeters long. The new products developed by Dutch horticulturists quickly gained a place in domestic and foreign stores.
