A few advantages of using solar greenhouse in applications today

The greenhouse is an effective way to solve inter-seasonal growth of agricultural products and regional shortage. In recent years, agriculture greenhouse has made a great improvement in protected agriculture in China. Especially with the development of science and technology and the improvement of people’s living standard, the application of intelligent greenhouse planting has become the inevitable trend of modern agriculture development in future.

Solar greenhouse generally refers to the energy-saving solar greenhouse, which is a unique type of greenhouse in northern China. In other words, solar greenhouse is a relatively simple type of building with the full use of solar energy. Solar greenhouse is not heated indoors even in the coldest season, but only rely on sunlight to maintain an appropriate indoor temperature to meet the needs of vegetable crop growth. In general, configuration of solar collectors and energy storage unit storage-type solar greenhouse can improve the microclimate of the crop in the greenhouse. At the same time, solar greenhouse can also guarantee the normal growth of crops in the cold season and the cold region. In addition, glass greenhouse has been popular for many years. For the one thing, greenhouse materials can contribute to heat absorption. For the other thing, glass greenhouse can maintain certain temperature and prevent heat loss inside the greenhouse.

Technically speaking, the working principle of solar greenhouse is to make the plant light and action exuberant during the day to generate a lot of oxygen while at night the plant releases carbon dioxide through respiration. Considering that temperatures inside a solar greenhouse vary dynamically throughout the day, the solar heat storage system has been developed in recent years, which has a good heat storage capacity to effectively improve the air temperature and soil temperature in the greenhouse so as to provide suitable environment for plant growth. In most cases, solar greenhouse must have good lighting roof, which can maximize sunlight, heat preservation and heat storage capacity, and also can minimize greenhouse heat dissipation inside. The good insulation performance is the distinctive feature of the solar greenhouse. For example, the general solar greenhouse can keep the indoor and outdoor temperature difference between 15~20℃ without heating. And the better designed solar greenhouse can even reach about 30℃, which is the main reason why the solar greenhouse becomes so popular in commercial agriculture these years. Good daylighting is another major feature of solar greenhouse. Generally the light transmittance of solar greenhouse can reach more than 70%, which is not achieved by single plastic greenhouse or multispan greenhouse in applications.
