In recent years, due to the vegetable greenhouses have the advantage of high yield, quick, less disease and insect pests, and make vegetables in advance, or to extend the time to market and so on, by the farmers welcomed. But in the north, especially in Jilin Changbai Mountain area, due to the cold winter greenhouses only idle. It does manage individual farmers use soil heating heating, due to high cost, not economic benefits, farmers had to winter at home "cat Winter", affecting the income. Antifreeze warm evening closed greenhouses, stamped cover, check leaking, prevent air entering the shed. Areas where conditions permit should take a multi-layer cover, the studio set up in the plastic shed or hut, covered with straw mat or nonwoven fabric and warming. At the same time pay attention to ventilation, reduce greenhouse humidity, ventilation to try when the sun rises to a certain height after, sunny day can be carried out at about 9:00 am. First yer canopy cover, and then open the door and rolled south side of film greenhouses ventilation, but in windy weather, to roll the leeward side of the film, do not roll film windward side, to prevent cold air blown directly into the greenhouse. Off shed early afternoon around 4:00, the first covering big films, then cover the shed various coverings. Snowy weather to promptly remove snow on the shed, too thick to prevent the snow collapsed greenhouses. The introduction of green warm carbon fiber heating cable electric heating technology, we can completely solve these problems, and can control the temperature change inside the greenhouse, to better promote the growth of vegetable plants and flowers! Green warm greenhouse application of the principle is the use of the whole heating cable emit thermal radiation heating plants for heat this issue has a strong absorption characteristics. By buried cables heat the soil so that the ground soil temperature, radiant heat energy to space to increase room temperature and ground temperature of the heating mode, the heating can not through the air, and direct heating plant roots. So that the plants were grown in a suitable warm environment, so that the yield and quality of the plant have higher greenhouse application upgrade to warm heating cable is inevitable for the following reasons: 1, effectively improve soil temperature, to ensure the production of fruiting vegetables condition. In the absence of the implementation of the technology, in accordance with traditional practice, the temperature inside the greenhouse is heated by sunlight, re-use heat sources such as stoves or radiators add heat to the greenhouse warming, although the above measures, we can only make greenhouse in the daytime temperatures reach about 12 ℃ (cloudy) night around 6 ℃, the greenhouse soil temperature (10 ~ 20cm) is generally only about 9 ℃, shed temperature in such an environment can only meet some leafy growth needs can not achieve normal growth and development of fruit vegetables temperature requirements; other winter irrigation water temperature is generally only about 4 ℃, thus watering indoor ground temperature is too low after the problem has restricted the growth of winter fruit vegetables bottleneck. 2, analyze the reasons for non-uniformity of temperature plastic greenhouse mainland, make up for its shortcomings. Since the position of greenhouse cultivation bed soil and acceptance of different sun angles, there are differences to absorb the sun's heat. Moreover, a large amount of heat on the south side. Thus, the greenhouse geothermal exhibits non-uniformity distribution: generally the lower south high north. Therefore, we must take effective technical measures, the use of green heating carbon fiber electric heating cables to warm geothermal greenhouse only to achieve more uniform level to ensure that the greenhouse vegetable crops relatively consistent growth. 3, create a variety of root crops need to be appropriately warm. Since the root depth and temperature and soil temperature requirements of various crops is different. From "The main vegetable crop root mass depth and temperature requirements table" can be seen, only the artificial creation of various types of crop growth and development required temperature conditions in order to meet the normal growth and development of all kinds of fruit vegetables crops. So the greenhouse to get normal plant growth and development in all seasons, you must use the green heating carbon fiber electric heating cables to warm.
