| Abstract:
China has become the largest protected cultivation country with protected cultivation area over 2 million hectares. About 50% of greenhouses (including standard plastic tunnels) in China are the traditional, low-investment solar greenhouses composed with non-transparent wall and gables in the north, west and east sides, respectively, and transparent plastic incline roof in the south side. To identify what can models do for the crop and climate management of the Chinese traditional low investment solar greenhouse, firstly, the special structure of the solar greenhouse is described. Then an overview is presented of scientific and technical issues that have to be solved in order to achieve suitable crop and climate management in the solar greenhouses, and the roles of models in solving the problems faced by the crop and climate management in the solar greenhouses are analysed. Thereafter, the energy balance of the crop canopy in the solar greenhouse and its differences from that in normal greenhouses are described. A brief review is followed on the state of the art of the simulation of the solar greenhouse system and its application to crop and climate management. The necessity to improve the applicability of the existing models to the solar greenhouse crop and climate management is stressed. Finally, prospects and needs for future research and development in greenhouse models and their applications to improve product quality and resource use efficiency according to the local technical and socio-economic conditions are discussed. | |
