The technology of combination of "sewage water recycling and ecological greenhouse" is firstly put forward, and it is applied to the protection of environment in extremely cold and high elevation area.

Through an innovative engineering design, our research enabled us to grow several kinds of aquatic animals and plants in an automatically controlled ecological greenhouse in a high density, intensive and water-saving manner.

Considering the characteristics of the domestic sewage at the medium-small Qinghai-Tibet railway stations,the ecological greenhouse is adopted,which forms a small artificial semi-closed environment at the bad natural condition of Qinghai-Tibet plateau so as to provide dynamic heat balance and the cyclic balance of O2-CO2 for sewage biological treatment.

Microclimate Characteristics of Plastic Greenhouse in the Summer in Southern Area of Guangxi;

Analysis on microclimate characteristic in sring of six-span plastic greenhouse in southern areas of Guangxi province;

Fertility Status of Plastic Greenhouse Soil in Hefei Region;

Effects of different N rates on the yield,N use efficiency and fruit quality of vegetables cultivated in plastic greenhouse in Taihu lake region

Relationship between electrical conductivity and chemical properties with characteristics of soil salt accumulation of soil extract(EC5∶1)in plastic greenhouse were sudied.

The results showed that the pH of the green-house soil was lower than that of the air-opening land soil and lower than that of the cereal cropland soil.

Test and consumption of chemical study with the influence of the state growth of tomato in the green-house which built in Coastal Saline -alkali soil by control the quantity of using the organic fertilizer and chemical fertilizer.
