Dutch greenhouse five new technologies

Albeit not spectacular, but in the Helan Wei Stellan (Westland) region formed a large greenhouse horticultural production and development of the world's largest and most concentrated areas. Large-scale economic cooperation between growers and the government's support for the horticulture industry in this region in the forefront. Horticultural growers in other countries as the Netherlands for the horticultural industry pioneer. Horticultural consultant CasvandenBerg said that China's greenhouse growers have begun to imitate the Dutch production. Let us know what the Netherlands has made five new technologies. GrowlabPlantivity sensor monitors environmental factors in plant growth the key is how to master the target temperature, light levels, humidity, etc. are suitable for plant growth. Hoogendoorn Automation company produces GrowlabPlantivity sensor allows growers to monitor plant growth activity. This sensor to the selected blade through regular reflection light beam emitted to calculate the strength of plant photosynthesis. Thus, for the kinds of plants designed software can calculate the whole plant dry matter produced per hour. Hoogendoorn Automation MarkChivers UK general manager, said: "The purpose of this sensor is to use the plants 'speak', let us understand the plant water content, leaf temperature and sap uplinked circumstances. Although the use of plant sensor is not new, but its use by the industry in the UK is also very small. "Plant and environmental data monitoring sensors are used in a large greenhouse feedback system is used to control computer environment monitored by the feedback factor is to meet the requirements, the need to take action to regulate. It also enables growers to analyze the previous growing conditions, access to adjust planting conditions in order to influence plant growth and vitality of the experience. Planting Laboratory (Growlab) is a growing technology company (GrowTechnology) and Hoogen-doorn Automation product of cooperation, which was founded five years ago. The former provides software and plant cultivation technology, which provides hardware devices. It grows stations using Hoogendoorn Automation 12 light sensors can measure physical variables, including the effective radiation intensity of photosynthesis, conductivity, plant temperature (via infrared cameras), relative humidity, carbon dioxide and air temperature. These sensors every 5 minutes once sent back to the observatory data, observatories calculated according to the initial data another 11 "virtual sensors" result. These include suppression and non-photochemical vapor pressure deficit. Fortunately, the growing technology companies also make recommendations for plant physiology to make these results become less abstract. These huge data via ADSL data transmission lines to Amsterdam's central database, and then make growing conditions on plant growth impact assessment report. Planting techniques HansHein sales manager, said: "By examining all of these factors will be able to find out which one is the limiting factor for plant growth. "He also said that such a sophisticated monitoring helps to control plant pests. "For example, meteorological factors that cause mildew problems. Pollution of the environment with chemical control, insecurity, high cost and inhibits plant growth. In the mold before they occur, by adjusting the relative humidity prevent it, the effect is obviously much better. "VillaRosa is Helan Wei Stellan region a rose nursery. The use of growth nursery observation system has been a year. One of the main nursery RonvanderKnaap said: "We get a lot of data from the sensors useful things, such as we mastered the increasing light plant growth can not increase the amount of the critical point. We also learned from the experience of other users. Using this system improves the predictability, increase production, to avoid some mistakes. "Integrating meteorological observation instrument planting techniques companies use a variety of sensors developed control system, including the use of some of the gardening industry was not originally designed for the sensor. Airmar weather instrument was originally used in the maritime industry. This American-made, integrated ultrasonic device can measure wind speed, wind direction, air temperature, barometric pressure and relative humidity. HansHein said: "Many growers in their greenhouse at the top with weather, but limits the activity of the life of these stations. Up to the top of the greenhouse grower must maintain weather instrument, otherwise it is not accurate measured data can not be used. "HansHein admitted:" This integration of meteorological instrument price is not cheap, about 700 pounds each. But we see is the quality rather than price. If the instrument measured data is not accurate, then in order to save money while buying this instrument is undoubtedly a very foolish. So we will use this year to do the experiment and meteorological instruments to develop a interface it with other systems integrated together. "Wireless video surveillance Rijnplant Company plant 8,000 square meters of anthurium" production factory "located in Westland region, the" factory "applied to a complex set of plant monitoring and delivery system. In the area of ​​25,000 stock pots anthurium, each basin is always placed in a small plastic "base", the small "base" Ryan has a radio frequency identification tag. Through it, the control software (GrowOrder) can be precisely positioned on it and give potted potted assign one including variety, color, height, and the amount of information such as flower "plant passport." All pots are placed on a conveyor belt control 450 bench. Most impressive is that all potted regularly transferred to a visual detection apparatus using the installed cameras at different angles to identify plants multimedia features, entirely automatically collects information about each plant pots. When you issue a command to transfer 1,000 pots with three varieties of plants magenta flowers, regardless of the time the 1000 plant pots on which a bench by a computer-controlled conveyor network will send them to the distribution area. No human intervention, over 99% accuracy. Automatic watering is management control. The company sales manager MartinevanRijn, said: "This means that half of the labor savings, the available space has been 100% utilized. "This system is composed of WPSHortisystem and planting technology jointly developed. Has the capacity to promote Dutch greenhouse energy prices last year launched a competition supported by the government, aimed at finding a way for those who greenhouse energy into production by the mighty way. In this development direction of one of the most promising development is located in the town of a 5000 m2 Bemmel model for greenhouses. It consists of ornamental plants manufacturer StefHuismanBV operations completed in May this year. The greenhouse is divided into two parts, according to the conventional heating and cooling half, the other half of the fine metal wire 150 into the heat exchanger. They are the first to be arranged in a production greenhouse. The heat exchanger can heat the air in the greenhouse switch to water in the water, then the water is recycled to the underground storage of irrigation. When the ambient temperature decreases, the water is pumped back again. Greenhouse owner StefHuismanBV declared, when the outside temperature reaches 30 ℃, the experimental part of the greenhouse temperature and routine control of part of the different greenhouse maintained at 25 ℃. Netherlands Foundation for Innovation greenhouse HansKoehorst project manager, said: "Summer has more heat into the greenhouse, you should consider full advantage of those extra calories. Water in the pipes of the greenhouse heating greenhouses clearly not enough heat, but it is useful, for example simple device can be heated. "
