Crops are grown in the national conditions. The environment factors such as temperature, humidity and light irradiance have its regular pattern. If crops were cultured at fixed environmental conditions, the growth characteristics may be differed with that cultured in natural conditions. Because of the limited function of experimental apparatuses, many experiments were performed by growth chambers and the fixed environmental conditions were used to replace the natural condition. In this study, the novel growth chamber that could simulate and control the aerial environmental pattern was applied. The Brassica rapa chinensis were cultured in three different environments: variation temperature, constant temperature and net house. The light intensity was set at 80 μmolm^(-2)sec^(-1). The cultured period was 30-45 days. The investigation characteristics of growth conditions were fresh weight, leaf area and chlorophyll content. The experimental results indicated that the significant difference of growth characteristics was found among these treatments. The cultured results at variation temperature were better than that at the fixed environment. For the biological and agricultural experiments, to use the variation temperature setting of growth chamber is more reasonable to simulate natural environment. A growth chamber with the ability to provide the variation temperature environment is worth recommending for studying of the effect of the environment factors on the plant growth characteristics.
