Advance of study on irrigation techniques in greenhouse;

According to the analysis of the content of HA, microorganism activity and exchange capacity of the raw material to produce the HA microorganism liquid fertilizer (the vegetable specific-fertilizer in the greenhouse), the best raw material produced for the liquid fertilizer was made certain.

Occurrence characteristics and biocontrol feasibility of plant diseases in greenhouse were analyzed and some actual applications exemplified.

The variety rule,the test method of the carbon dioxide density in the glasshouse and the design of the control systems were introduced in this article.

To study the tiny difference of weather in glasshouse,this paper analyzes that the radiation of the sun in glasshouse is decided by the angle of radiation ray cast down in the horizontal plane from the angle of the astronomy radiation.

Automatic Irrigation System in Glasshouse Based on LOGO! Control;

Calculation of crop evapotranspiration in greenhouse;

Study on the Effect of Nursery and Fertilizer Application to the Organic Cucumber in Greenhouse of Beijing;

The intelligent greenhouse control system based on GPRS;

Carried on the airtight awning room spraying experiment to the cold aerosol sprayer, the research cold aerosol has executed the medicine technology in the south middle-grade plastic awning room spraying compatibility, the droplet subsidence distribution rule, the droplet deposition density and the experimental parameter establishment rationality.
