A, when E < B, the photosynthetic rate increases with the increase of light intensity, and the conditions such as temperature, moisture and inorganic salts are suitable, not to mention the CO2 concentration, so the CO2 concentration will also increase the photosynthetic rate at this time, so A is correct;

B, when B < E < C, the light intensity is increasing, but the photosynthetic rate of plants is no longer increasing, so the main factor limiting crop yield at this time is CO2 concentration, so B is correct;

C. When E > C, the photosynthetic rate of plants decreases, which may be due to the closure of stomata due to too much light. At this time, shading measures can be taken to ensure the maximum photosynthetic rate of crops, so C is correct;

D. In case of cloudy days, the greenhouse needs supplementary light, and red light or blue-violet light is the most effective, because the pigment mainly absorbs red light or blue-violet light, so D is wrong.

So choose D.
