Brush Cutter, high branch chain saw, chain saw, lawn mower, the wind fire extinguisher, hedge trimmer is the most commonly used garden tools, greenhouse heating costs as energy prices continue to rise, more and more high. So is there a greenhouse does not require heating, and production in the winter? The answer is yes. National Agricultural Information Engineering Technology Research Center for the original composite Greenhouse, successful resolution of this problem.

National Agricultural Information Engineering Technology Research Center, the reporter saw this energy-saving greenhouse, which is located in a semi-underground. From a distance, the wall outside the sun panels, and the greenhouse is not much difference, went inside I can not see so special. The creator of the greenhouse Liu Zhi briefed reporters on the principle of a greenhouse: greenhouse in a semi-underground, underground depth of 80 cm, to draw ground temperature as much as possible so that in the winter, and the relatively low height of the surface of the greenhouse, you can also reduce the impact of the wind. In fact, the most important greenhouse mystery lies inside the support wall, the wall with metal mesh and cement casting so can absorb more solar heat during the day and night heat released.

This greenhouse is called composite energy-saving solar greenhouse, because the main greenhouse there is a secondary "brother" --- the external walls of the slope after the greenhouse. The auxiliary greenhouse slope angle is less than the angle of incidence of the winter sun even in winter it does not produce light corner. The slope greenhouse generally used as the Spring and Autumn shed, even if not directly come in handy in the winter and can also be the principal greenhouse temperature insulation effect. Furthermore, both before and after the greenhouse is formed of an arc, wind speed can be reduced, thereby reducing the impact of the main greenhouse, the insulation indirectly play a role. According to actual situation, the auxiliary greenhouse can be built farms for animal husbandry.

This greenhouse is not only insulation, water-saving. Designers, purpose-built greenhouse peripheral the gullies and storage wells, the rainy season, it can rain survived. Retention of rain water through the filter processing, you can give the plants in the greenhouse watering, thereby saving irrigation water.

It is understood that the composite energy-saving solar greenhouse in the winter without heating will be able to maintain 12 ° C to 14 ° C, summer cooling can shade net, wet curtain facilities. At present, such a greenhouse area of ​​an acre of land in the total cost of 20 million, can be widely used in the production of flowers, vegetables and other plants.
