Dutch facility cultivation of high-standard glass intelligent greenhouse is based on high-standard multi-span greenhouse, adopting advanced cultivation technology and modern hardware equipment to improve the output value per unit area, and its vegetable crop output value level is in the leading position in the world.
Intelligent environmental control system In terms of environmental control, all greenhouses in the Netherlands adopt automatic control, which can automatically monitor, record and control environmental factors such as temperature, humidity and CO concentration in the greenhouse, and provide suitable environmental conditions for tomato growth.
Ventilation and cooling treatment of skylight, circulating fan and internal sunshade in greenhouse. Ventilation and cooling in the greenhouse are mainly accomplished by opening the skylight on the roof of the greenhouse. Modern multi-span greenhouse can control whether the skylight opens and the opening angle according to time, temperature in the greenhouse, external lighting conditions, indoor humidity conditions and other factors.
Treatment of CO2 concentration In the greenhouse in the Netherlands, a CO2 increasing system was installed, and the CO2 concentration remained at about 900μ mol/mol, which increased by more than 30%. CO is heated by natural gas boiler, which is an auxiliary equipment for greenhouse heating.
Modern cultivation techniques are the core of greenhouse production in Holland. After years of development, a modern production technology system has been formed. Taking tomato production in Red Harvest Farm as an example, modern production technologies include variety selection, plant management technology, soilless culture technology and grafting technology.
Automatic irrigation system The Dutch use precise control system, which can not only adjust the irrigation water quantity according to different periods of crops, but also adjust the irrigation water quantity for one day according to the solar radiation, so as to ensure that crops meet the needs and avoid wasting water resources.
In the aspect of precision fertilization quality, the formula of weekly fertilizer is that the producer distributes the nutrient solution mother liquor according to the formula in a certain period of time according to the test value of liquid return and rain water. In terms of dosage, the dosage of tomato nutrient solution is controlled by fertilization system and varies according to environmental factors such as temperature and light.
Pest control system The Dutch greenhouse pest control adheres to the concept of source control and induced control, and gives full play to the advantages of natural control and ecological control based on the precise control of temperature and humidity and the construction of beneficial insect ecosystem.
Pest isolation system Dutch greenhouse has been building a closed crop growth system, and there is a strict disinfection process when entering the production greenhouse. A specific operator must sterilize the tools after each operation.
Accurate environmental control and appropriate temperature and humidity conditions in the greenhouse are the key factors to ensure the normal growth of plants and less occurrence of pests and diseases.
The artificial induction and use of various prevention and control of pests and diseases in greenhouses in the Netherlands are mainly biological control, supplemented by physical control and chemical control.
Monitoring and early warning mechanism: taking tomato production in red harvest farm as an example. The plant protection specialist of the farm regularly monitors pests and diseases every week, and adopts pesticides to control pests and diseases beyond the control of natural enemies in time.
Intelligent reduction of labor costs is one of the primary costs of greenhouse production in the Netherlands, and reducing labor force and labor intensity is the policy that greenhouse production in the Netherlands has been pursuing.
To sum up, this is why the Netherlands can make up for its own disadvantages and increase production in a more reasonable and scientific way. Geographical advantage will not be the decisive factor, everything depends on human efforts!
